Dynamic Mechanism Bearing Loads

Hi folks,

I am trying to work out how to get bearing reaction forces within a rotating assembly.

Picture a simple shaft, with an eccentric mass towards one end (kinda 'L' shaped), then support it in 2 bearings at each end and rotate it.

The eccentric mass is closer to one bearing than the other, so I would expect the bearings to see different loads.

How do I determine these loads in Pro/Engineer?

I can set up a mechanism to rotate the assembly, but I am not sure how to constrain the shaft in 2 different places, i.e. at each end in seperate bearings, so that I can measure reactions in each bearing.

Any help much appreciated.

Thanks in advance.

Regards,

Jon Reynolds
