I have a mechanism that I need to analyse including the frictional torque at the various articulation points, but cannot find a simple way to do this. It must be a very common requirement.
I have a mechanism that I need to analyse including the frictional torque at the various articulation points, but cannot find a simple way to do this. It must be a very common requirement.
When I was analysing mechanisms I employed Mates to connect the links, and Mates, being virtualisations, have no friction.
To calculate friction I would have had to model real world bearings and employ 3D Contact and make assumptions about lubrication.
Given the limitations of 3D Contact (it is an approximation and cannot accurately represent contact area), I think you would be wasting your time.
FEA might do a better job of contact area but I don't see how you could run dynamic FEA whilst analysing motion.
You could request that SW be compiled for a quantum computer.
You can just add a friction coefficient to the mate definition. Its under the analysis tab in the mate definition.
I think you are telling Richard how to specify the friction to SW, whereas my reading is that he wants SW to tell him
not just the coefficient but the resistance to angular motion.
Thanks Bill
I originally searched HELP for ages with no luck.
