abaqus自冲铆接仿真步骤

yeah！ 嗯嗯嗯。

四川某街工艺。

我们要来练习这个啊，金属版的冲压，你经常分析啊，那这个练习呢，我们茁壮于 静态哦，什么意思呢？那我们目前呢都是用这个显示求解器在做求解，那从前面的单元有提到显示求解器呢，他非常适合拿来解啊， 这种高度不连续非线性的问题啊。但是呢显示修改器呢，也可以拿来解静态问题，那我们透过一些模拟的手法哦，那你可以想象其实我们在这个经历学上面提到的这个静态了，他不是完全跟时间不相关啊，我们是已经默认我 我们的力量加载是非常长的时间，所以他接近于一个静态的反应，所以你静态就是用这种概念啊，我这个用一个手法让这个加载时间呢，好像很长 哦，接近于一个静态，那最后呢，我们都要评估这个动能跟未能的比呢，小于一个比例，我们就可以说这是一个这个拟静态的问题。 好，那这个练习党的呢，放在这个 worcr 第三个哦， dbody 啊，这个资料夹里面，那 里面呢？总共有这个。呃，两个资料，一个是这个图档啊，模型图档再来呢，是这个塑性资料都帮大家准备好了，所以呢我们就把这个档案呢复制到公众目录底下，那我个人习惯是放在西朝天蓬底下开一个资料，这样好，现在呢我们把软体打开啊， 我习惯呢透过这个卡面，好透过这个命令提示资源打开，然后呢直接输入 iphonex c a， 好透过这个方式开启呢，他可以直接把我们的工作目录呢 指到我刚刚开启的那个路径，所以呢我们从 fel 里面的这个工作目录我们可以确认在这个正确位置就可以开始。好，那因为这个题目呢，答案都已经帮大家画好了，所以其实大家不需要自己在啊， 透过帕尔姆组来会，我们只要透过英破尔会入帕尔，会入零件。啊，那这边呢，第一个就是 s t， s a t 啊，这是我们的会入格式， s a t 会进来之后呢？

啊，大家好，接下来给大家演示一下啊，我们的自出卯接啊，这是不需要打孔的啊，首先我们装配我们的卯接头，根据不同的使用的功能啊，我们选用不不同的，这个卯接头 好，装配铆钉好，接下来啊，我们在这里进行一个铆钉啊，我们现在是不用打孔的啊， 好，到达压力以后自动泄压了啊，不需要我们怎么去复位，这是某接完的一个，这是正面啊，这是没有压痕的，这是背面。

分享一种自称是卯接结构。自称是卯接结构是一种机械连接方式，实现相似或组合材料类似的牢固机械连接。即使是两层以上的材料组合，也可以实现卯接 中空铆钉穿透材料上层，并在底膜的影响下延展。因为为穿透底层，连接外范围小，并且不透气不透水。你学会了吗？

了解干货黑科技，就听一号天团说，大家好，我是路虎一号专家天团的李露露，今天我来给大家科普一下什么叫航空级的自从保健技术。 这种保健技术是一种冷链接的技术，他不同于以往传统的焊接技术，他可以为车身提供更好的强度，更高的流转钢组以及更优秀的耐腐蚀性能。 自动保洁技术，他是通过液压缸或者四伏电机所提供的动力，将铆钉直接压入带保洁板材， 在保洁板材在保定压力的作用下，从保定发生塑形变形，成型以后通灵于保膜之中，形成一种稳定连接的全新的铝材连接方式。自从保洁工艺所采用的压力高达六十到八十，线流相当于一头陈年非洲象的胜利，他的疲劳强度相当于 传统的焊接要高百分之三十。采用自动保洁技术的车身连接处不会产生热变形，没有焊接飞溅，整个保洁过程仅需要提供加热空气和线的这种非常智能环保的连接方式，比传统的焊接车间要节能百分之七十。

带吸力， 原厂的工艺，原厂的效果。

大家好，今天一起来做个铝合金板冲压成型的小案例。主要技术点为，定义材料的损伤失效接触设置钢铁约束。案例，采用外部模型导入检查起和和确定单位置， 确定单位至为米。创建两种材料，铝合金和结构钢。集中铝合金的相关参数如下，紧切破坏参数如下， 子选项，损伤演化采用位移形式，失效位移零点零零一， 密度为二七零零，弹磨为七十普松比零点三，塑性定义如下，点击确定创建机构钢。 定义密度以及弹性，点击确定分别创建两种洁面壳， 选择厚度为零点零零五、选择材料为铝合金。 创建骚类的选择结构 钢，分别赋予部件磨具为 solid， 铝合金板为 share 压床位 solid， 鸭头为 solid。 进入 max 模块， 为了后续的动画效果，将铝合金板网格全局尺寸指定为零点零零二 进行划分， 随后其余部件均采用自由划分，并均指定尺寸为零点零四、进行划分， 看所有网格划分后进行装配。 求解设置选择显示动力学 设置求解时间为零点零零一、默认为自动增亮部，点击 ok。 长输出设置， 选择默认再相互作用模块。创建钢体约束，分别选择冲压部件设置为钢体约束。 完成设置后，创建接触属性包括七项行为，法项行为，七项行为采用罚函数定义摩擦系数为零点零五， 法向默认接触指派为通用接触， 选择接触属性，点击 ok。 边界条件的设定， 固定住冲压部件， 并对冲头约束掉除 z 方向外所有自由度 在预定一场里面，指定鸭头初始速度 为 z 方向上负八百，点击 ok， 最后提交作业进行求解，查看 求解结果。 通过后处理我们可看到铝合金板材的冲压成型及冲击下板上的硬力波效果。

greetings to all and welcome to the channel sometimes 05， so this is the second， we do tutorial of abacas interactions the first video tutorial， i explain contacts or intexts in abacus， briefly and what type of surfaces are required for those intexts so here you can see we have a number of component and assembly like this is the beam component column component in between we have one plate component and we have four bolts also two bolts are in this side and two bolts are in the side okay， so first assemblies it is very very important to define the interxence or context properly the rice resort will be misleaders apart from in this video tutorial， we will also see how to apply the pretension look for the board component， so you can see here up to the 10th increment here we are getting only the pretenser load and it just is our due to the pretension load and after the tent increment only the applied force is in the subject you can see okay， so let me play the simulation let's go home play so up to that we have pretension load then the incremental load or applied load is a start and after the tenthing humid whatever statisticide generator due to that lower will be computed in the shape second， so let me continue the process just go for here visualitis and instead of visualitis and part modeling so these components are already created and if you want to create those component very easily you can go for creating by part modeling itself in abacus or you can import those model from the cat softels so i'm not wasting time in the modeling after the modeling， we have to go for define the property in property we need to create the material we need to create the saxon and we need toss and the saxon so just go for create the material by name of steel to 35 define the properties like general property density so on it 20 era studio power minus 12 okay this material is considered in mm 10 and second unit that's why the density will be look like that before mechanical plastic property just go for elastic yanks modulus 210 e restrict bubble 3 and the poison cell 0.3 and the plastic property， plastic and plastic property the illustrates for the steel 2 35 we have 2 35 actually and plastic stain values zero okay this material is for the plate and column component we are going to create another property sorry another material for the bold so define the name material name is bold to go for define general property density seven eight to zero erastic pound managed 12 then i can go for defined the last again plastic property so after defining the materials we need to create sections we are going to create two sections one is for still two 35 type of materials type of components okay， so name also i'm giving is 2 to 35 same material and another for bold component okay， so just bold solid homogeneous and select here and material let's board go for create now we need to assign the property or we need to we say we need to assign the sections okay， so just go for create it is asking for components select this part i'm don't going to create any set so if you want to create set just check on and define them otherwise go for and check before done okay， so steel property i'm assigning here and similarly for the board yeah for board we have different property just select the part and let's go for a board okay， similarly assigned the property for two other parts so once properties assigned you need to go for assembly actually， we need to assemble those all components， but i don't want to invest time and assembly actually as well as i spritted my geometry because i want to define all element as instructs art mess if we are not going to split softer reasonable to define the structured mess see here we are not looking the assembly command in briefly and spreading command in brief， we are looking for the intexts and contexts so the main focus is intext and so just go for here stape okay at the start of video i already mentioned we need to create to a stape one is for pretend some condition， but pretense and load if my name is pretends on static general continue increment go for some small initial increment that conversance will locker and maximum increment we need as point one for six side， i'm taking here a thousand increments just go for okay again， go for creating the second step that as loading step go for continue and same parameter increment parameter we have to define so you can see feel the question and history question is automatically assigned if you want to make something this you can go for it so after step you need to define here in trixon， that is very very important， but before defining in trixon， i would like to define some loading conditions those are nothing but over pretends and loading conditions so just go for a load and go for click on load manager go for create say both load first bl1， i'm just going to copy this for further use in the mechanical， you have to go for here both load click on continue well， i'm sorry we need to go for choose the first step just go for this mistake， so this pretense in this tape click on the board load， click on the continuum and now it is asking for interior surface or board sank surface so everyone know the board sank and we need to select the board sank surface but the problem is that if i go for selecting directly we are unable to select okay， so what i have to do i have to go for here display group options just click on that and go for your part or instance i want to see only on the balls and this this back component that is column actually， so i'm going to hide my beam and play just go for select those by pressing ctrl click on remove now go for this mess very easily you are able to select now the sanc surface or those cylindical surfaces okay one more thing here we have four boards， so we have to create the load four time okay， so board sanc surface and select the surface any of them sank surface you can select this surface and it is asking for cut position okay the cut position is nothing but like if this one is our slandiggle surface at what distance or at what passengers value you want to create a cut section their software will create automatically the pretense and loot so at the exact limit i want to apply so just go for your 50 percent and click on done they find the magnitude value for potential load we have value as 90430 and tip on ok this one is of a pretense and load and those arrows are representing the pretension vondrigan decent similarly， you have to define the pretense and load for all words so let me do this okay， so all board load is defined i also want to apply the point load， so just go for and hide your assembly just click on that icon that is replace all all you can go for here again the display group and select those all components and click on add okay， otherwise you can directly use this options and hide the all components okay， so to define the point load again we have to go for create okay， the point load， i want to create on the loading strip not on the pretension is to define the name like point load and go for here concentrate load point load keep on continue select this point i made one sprit here that i can easily select this point define the value that is in the negative wire directions， so i'm defining negative and well just skip on okay， so make sure you are creating the point load in the loading stick not in the pretension stip okay， one more thing whatever， the pretension load you are created that will be propagate for the second step so we can say whatever the pretension result we have that will be carry on for the next step i'm also going to create some constraints so just go for here constraint but when you can decent manager click and create define any name i want to fix this this column top and bottom so just go for here at the symmetric or end caster just go for select this face as the first face okay， when i selecting any face this is not going to highlight because i uncheck this options if you want to see the surface before selects and just check on this and now you are able to see the surface before the selection okay， select this surface and now click on then define encoster options so this component is fix from these to end and one one mistake with it by far it's we created in the loading step so just go for a move left and move left left i want to clear this boundary condition in any solid step okay， now just go for dismiss now the important task to creating the inter accents okay， so there are two way to generate or create intractions one is like manual way， one is auto detects and options next we do tutorial we will see the auto detects and options and what are the limited sense of that auto detects and options but now we are using the manual contact assignment in my previous video i mentioned that we need to define the contact surfaces for the contact or interact cents and those contact surfaces may be the note basis maybe the element basis if you define the element based surface you can select those surfaces for master as well as slave， but the note based surface can be select only for the slave i briefly explain those type of surfaces in my previous video highly recommend to go with this video and then only you have to follow the other intexence video so now let me have it overview where we want to define the contacts or connections okay， see it is very clear one contact is between column and plate one contact is between plate and that beam component okay， then we have intractions or contacts between that plate top face and this bold interface interface means i will show you my interface similarly we have here contact the interface of the world and this face okay， so these contact are how to create and this would be tight connects in between this plate and this beam component okay i'm assuming that that those two components are rigidly fixed with each other so now creating surfaces very very important i'm not going to create the interacts and directly because it is a little bit landy here so first we are going to create number of surfaces and we realize those surfaces to define the interacts and definition okay so let me create the surfaces not part busy surfaces just go for hide those parts and go for here in the assembly and surfaces okay see here we have existing surfaces like both surface， one， two three four why because we define the pretension load and softer will automatically decided or define those surfaces so now let me create the another surfaces just go for the first surface as this beam internal surface that going to be connected plate so i'm defining as beam click on continue then you want to select that internal surface of the beam， but that is problematic you are unable to select that internal surface directly so what do you have to do you have to go for again those tools display to the click on that display options and i want to see only on this beam component so just click on beam and click on intersect so all other components will be hide so just go for rotate little with this component i'm changing the rotation center and now go for rotate and go for here dismiss and now you are able to select the surface very easily okay select the surface and click on done so see here you how the beam surface now again go for sew all the components according to the requirement we will sew and hide those components now another surface we have to create this display top surface so i'm defining name is play it and tp this is the top surface you can continue selecting the surface okay now again we are getting some problems problem look， if i go for selecting the surface individually it is too much problematic for me so instead of indisal method i go for here by angle options define some angle and select the surface so whatever surface having the angle less than the 20 will select the automatically so just go for done see the top plate face is selected so i just go for rename this not tb that is tf played top face okay similarly plate bottom face so to selecting the bottom face i need to hide this column component， so just go for here remove remove water， remove this column or or you can go for this test tool， this spiritude and remove the column component just go for here dismiss again double click on the face say plate bottom face so bottom face click on continue and want to select those faces make sure you are in the angle option select one surface and soft automatically detect the all faces just click on them at the same time i want to create the sang surfaces also for the bolt， so just double click on that and say bolt sang surface ss just go for create define bianggle select the one surface auto automatically detector all other surfaces okay， similarly these surfaces and these surfaces now go for them i also want to select the bolt top and bottom inward physics so for this i have to go for hiding this split component also just go for a game the display manager and go for here the hard say click on the plate component and click on the remo icon okay， so just again double click on that i'm selecting the bold top surfaces or top faces the skip on continue again select this first second turn and pull this displaces and keep on done similarly， i want to select this bottom faces also the work click define the name bold bottom face a bottom surface just click on continue select these surfaces besidely select first second turn and foot surfaces okay， go for the spring manager check on the column component， i want to create the surfaces for the column top and column bottom also， so just go for define the name by the click on the surface column top face or top surface click on continue make sure you are using this options now if you want to deselect those surfaces just again go for here indisial method and by pressing control button deselect this and deselect this now click on done and similarly column bottom surface or bottom face you can continue select by angle options select this surface and in this surface now again go folder by indison options and i want to deselect those okay as well as i want to deselect those see those only surface are selected now you can done last we need to select the surfaces that's going to be contact with the respect to the bold sank okay， so for that what i'm going to do i'm going to hide the all of the parts i'm just going to keep the plate component and the column component okay， very component and now click on column and add so these surfaces are going to be connect with old sank， so i'm just going to define the name and double click on that and defining name is whole sank you can continue okay again by angle options select this subface and this subface by suppressing sub button similarly here similarly here also and here also okay do surface selected click on done so now we are done with generating the contact surfaces and go for here so all the component and now we are looking for the contact definition so before defining the contact we need to create the property contact property just go for create okay intacts and property one or we can say any other name so say frictional contact， frictional contact and just go for contact create mechanical behavior tangential behavior is penalty based fiction and i'm defining fixing cooks and s.3 and normal behavior is the hard contact just before okay， i will explain those hard contact and penalty based method we will talk on those in separately next video tutorial just go for dismiss go for definition click and create so intacts and one or we can say the sank versus whole contact okay make sure you are in the initial escape because i want to define the contact in initial escape itself surface to surface contact for abacus standard just click on continue so i not need to select the surfaces now i just go for here the surfaces options and those all surfaces those i created are available for me i need to select for the master surface， so the master surface will be the always larger surface if you have a reserved component then we need to select the reserved as a monster all all those things i explain in my previous video i suggest to go with that so this is the for hole sank this surface for the holes sank contact just click on continue now it is asking for the slave in the slave also i'm going to select the surfaces and those bold sang surfaces are my slave surfaces click on continue define the property this fixing property are already created and now click on okay， so in this way， we have to create the different different contact it is also possible to define different different properties for indisal contact okay but right now i'm just going to create only one property that i already created and i'm using that property folder all component okay， so just go for again create the another property this is between the beam component and plate component so the find name is beam plate okay surface to surface again continue select the master surface master will be our plate top this one is the plate top surface and slave surface will be our beam surface this this beam surface just keep on continue define the property if you have multiple property you can define and just take one okay similarly， i need to define the interacts and bit win plate top and this bold inner surface okay， so say plate what says plate top？ what says board inner top okay， so i'm defining name as board it select the plate of face click on continue surface and then go for both of face these these surfaces must be selected click on continue again define the definition and okay now again go for creating new property plate to column just click on create 8 bottom click on continue and again surface and column bottom face also the column top face now we can continue see now we have to defend the contact between these two faces like you can create column in both take on continue so this one is the bold bottom actually and column column bottom column bottom so here you have column bottom face surfaces and these are the bold bottom inner so bold button faces c now click on continue and click on okay， so all contexts are defined， but but we made one mistake see if we house has been and that connected to the plate with the fix and cofficient opponent that you would directly fall down okay， so what i all there told you we have to define a visit component a connection between the plate component and beam component so the beam plate components would not be connection actually here just go for delete remain all is okay so i want to define it by connection between the these two components just go for test mess and click on connector options here and click on those constraint manager click on create constraint type tye and click on continue it is asking for master surface just go for defender surface， master vanister please plate top surface so here the plate top surface， plate top click on continue again the slave surface and for the slave also i need to decide one surface that is the beams surface click on beam surface and click on continue so again it is asking for some definitions like discritizing method and those all i will explain those also in my feature videos make sure you are untagging this options add just slip surface initial position if you don't want to allow any adjustment into node and protestantial freedom also， i want to constraints to check on this options， but here i'm allowing the initial displacement or initial adjustment keep this options as it is and go for okay so now all intact sense and constraints are defined as well we define the load and bounce conditions also so now just go for a mess so as i told you by me nopesome is splitting we are unable to define the structured mess for the component promoting by default my global seating will be creative only when i limit through the technique so that's what i did i go for the local seating and selecting this edge and selecting this edge not by angle in this one and define some number of element like four element along that i want okay similarly for this case also here here also， i want the four element okay along the dub so i decided now just go for real mass options click on the mass select the all part， which you want to mass click on then in future i will create a separate video for the massing and folder splitting and abacus abacus massing algorithm for the 3d components are very very excellent so i will separately talk on that so just before here the job options make sure you save the file make sure you save you define the work directory just go for a year save file set work directory okay i'm using some work directory this one is my work directory okay， clip on okay， just go for here job manager create job one paralyzis and i want to use multiple code how i'm allowing 16 code memory see sometime if you have less memory in your system the solver， so some error like memories out of system memory， so you have to untake this options in case memory location， brush down and license estimates and okay we are we are just going to fix the ram or memory up to 90 percent of the available memory okay， we are not allowed to increase that just go for okay now click on data check or submit i'm going to submit directly click on monitor okay， so start writing the increment files or dv files so after few increments unless this is completed so let me open the result just go for dismiss and take on the result go for some standard view click on contour options and this is the final displacement so that it one masses distresses you want to change the distresses to displacement just click on here so this will be the displacement okay， so displacement desert is not that much important here because you already know the maximum displacement will be back here okay， so again go for the stresses and one my sister stresses so let me verify the pretension results in the first strip， so are two tenth or 11 implements see a two tanting human we have here pretension load and this is the effect of the pretension load on the column see by default the color button is a little bit different just go for here contour options and by default it is actually the rainbow options and now pick on applet， so this blue color is represented for the zero stresses it is a little bit disturbing to see the blue color everywhere， so so what you have to do？ you have to click on that color icon？ you have to select you have to define the name of the spectrum new spectrum you are going to create okay spectrum 2 and click on that blue icon and again， go ahead and go ahead and choose a default whiteest type of color okay， click on ok then ok and again see it still behind the envelope since okay just go for here the inspector to click on apply so now the lower result will be look like in the regular and click on apply okay， okay so these are some visualization options actually just let me play pretension then whatever the load we applied accordingly the stresses will be generated okay， okay， so i hope lots of things you learn here and especially how to define the interacts and contact surfaces and how to define the contact like how to hide the surfaces， so the surfaces and those those are all different things okay this is the softest click actually， nothing tortically or conceptually the conceptual thing i explained my previous video and in next video i also talk a little bit conceptually about the intractions properties okay that video will be very important， so being touched with my channel if you have any query or question， you can put that question in comment section or you can message me on wars up you can call me or you can mail me also my details are available in the description so that's all for this video thank you。
