workbench怎么给物体施加刚性约束

[1617836513]

我在做一个螺钉的扭转性能测试，我想限制住传动体的变形，并且在它的外侧施加远程位移，最后利用远程位移这个边界条件来输出反力矩。直接把传动体设置为刚体会和远程位移这个边界条件发生冲突，我应该怎么设置才能实现图二中橙色部分的“using plane elements to define the rigid surface of the screwdriver”

Hi Shiyu,

螺栓连接的性能评估，官网上有一些教程，您参考一下：

On top of that, when setting the drive component as a rigid body, it still has such a large deformation, why is that?

您是说变形量过大吗？预期的变形是多少？方便的话具体介绍下您模型的设置。
