wb模块的区别问题

wb12中有transient structural（ANSYS)和transient structural（MBD)，这两个模块的区别在哪里？要进行刚柔耦合动力学分析应该用哪个模块啊？

transient structural (ANSYS)is that specifically uses the ANSYS Mechanical solver. This type of analysis is used to determine the dynamic response of a structure under the action of any general time-dependent loads. You can use it to determine the time-varying displacements, strains, stresses, and forces in a structure as it responds to any transient loads. The time scale of the loading is such that the inertia or damping effects are considered to be important. If the inertia and damping effects are not important, you might be able to use a static analysis instead.

Transient Structural (MBD) Analysis using the ANSYS Rigid Dynamics solver.This type of analysis is used to determine the dynamic response of an assembly of rigid bodies linked by joints and springs. You can use this type of analysis to study the kinematics of a robot arm or a crankshaft system for example.

说到底，就是分析柔性体和刚体的区别，但是刚柔耦合动力学分析改用哪个模块呢？

没做过，但是感觉上用ansys要好些，不过这也和你想得到什么结果有关。
MBD

• All parts are rigid such that there are no stresses and strain results produced, only forces, moments, displacements, velocities and accelerations.
