Components for Bearing Connection

[coolsheng1977]

I have come up with this problem for long time. My two parts are connected by "Bearing" connection and I ran the model in Pro Mechanism successfully. I can track the RADIAL FORCE and AXIAL FORCE at the joint, however, my intention is to exactly find the X- and Y- component of the RADIAL FORCE (assume AXICAL FORCE is in Z- direction). I have to input the X- and Y- force into another tool to do further analysis, but now I just have the magnitude of the RADIAL FORCE. Actually I can run the animation and see the direction of the force instantaneously so that I am sure X- and Y- component force is there, but just I cannot find them.


Does anyone happen to have this problem fixed or have any solution to my problem. I really really appreciate your help~~~~

A "bearing" joint will not provide reaction forces resolved into cartesian components. Ball joints work the same way. You will need to substitute a 6DOF joint for your current ball joint if you need to obtain reaction forces resolved into the X-Y directions. Because it is a 6DOF, you will of course need to constrain the appropriate DOF along the directions required to arrive with a bearing joint. Once this is done, the joint will act like a bearing joint but will resolve reactions in the constrained directions.
