汽车B柱Rollforming成型的有限元仿真

在汽车车体构件制造中的辊弯成型工艺应用项目研究中,利用大型非线性有限元分析软件MSC.Marc研究了汽车B柱变截面辊弯成型仿真的有限元建模方法,主要包括板料模型和成型辊模型的建立、单元选择、边界条件、各种参数的设置及成型辊的速度加载等内容,然后采用刚性轧辊沿板料长度方向平动的方式对板料成型过程进行仿真模拟,分析了板料在...

Finite element simulation on automobile B-pillar rollforming

In the item of the car units manufacture by roll forming,the finite element model construction method on the automobile B-pillar flexible roll forming simulation was studied via the large non-linear Marc software,including mainly strip model,roller model,element choosing,boundary building,the setting of model parameters,the velocity loading of rollers and so on,then simulate the strip roll forming process by the rigid rollers moving along the strip,the deformation,stresses and strains in the primary,middle,...
