Bearing Connection Error on Static Structural

bangkither

Hi Everyone,

I'm currently working my tilt tables project on ansys static structural.

Previously, i using Fixed Support on bearing joint. Although, the the von-Mises stress (175 Mpa) is below yield point (245 Mpa) but i think its too big for the load given.

Sometime later, i found on youtube that ansys has bearing connection feature for bearing representation instead of fixed support. After that, i tried to delete the fixed support and change that with bearing connection and remote displacement at both ends. The remote displacement does lock the uz and rz DOF. But, after solving the solution i found this error on messages.

Does anyone know what happen?

Thank you

Hi @bangkither ,

The error message indicates that there is a rigid body motion. Can you please check if the model is properly constrained in X, Y and Z direction?
