The physical dynamics features in SW are cool, but can only take you so far. If you want to model actual response torque based on an input motion profile (position, speed, or acceleration) and visa versa, then you need CosmosMotion that is embedded in SW. We have been using CosmosMotion for several years at FANUC and we used it in 2005 and this year to determine what actual spring balancer we wanted to use for the arm.

I highly recommend the CosmosMotion add on for anyone designing mechanisms. It saves a bundle on prototyping and mock-ups.
