Hi all, I have a problem doing structural analysis, in the picture below you can see that I am applying two forces to the nut which should clamp the nut itself, when the nut clamps, The nut and the inner ring should gradually separate to reduce the stress on the inner ring, but the analysis result shows that the stress on the inner ring continues to increase. Does anyone know the reason?

Hi @luffy35737117,

Contacts can be the issue. Have you checked the contacts of inner ring with other parts? All the contacts of inner ring with other parts should be frictional or frictionless. Also, please share some more details like deformation and stress plot just to get idea of how the inner ring is getting deformed.

 

Thanks,

Akshay

Hello@Akshay Maniyar,  my inner ring For the spindle is set frictionless contact and the nut is set with a friction coefficient of 0.064.

This is the overall stress profile

This is the stress change at the interface between the inner ring and the nut

This is the overall deformation

This is how the inner ring looks deformed

This is the contact setting of the inner ring and the spindle
