基于设计CAE和DFSS的悬架控制臂开裂问题解决

Solution of Cracking Problem of Suspension Control Arm based on Design CAE and DFSS

应用CAE方法找到了某车型后悬架下控制臂弹簧盘定位孔在道路试验中开裂的原因,提出了通过结构优化来解决该问题的几个途径。采用DFSS方法进行正交试验设计并结合设计CAE技术进行了多方案的对比,找到了最优解决方案并通过了路试验证。

In view of the cracking problem of positioning hole on rear suspension lower control arm during vehicle road test, CAE method is used to find the cause of the problem, and several ways of structure optimization are put forward to solve the problem. Then multi schemes with orthogonal design in DFSS and design CAE technology are compared, and the best solution is found and pass the road test.
