I use SolidEdge but it costs. The package has a great 3D modeler which you can stress test. You then bring the first part into Assembly and you can make associated components off the initial part. You can also get it to operate on screen (even define gravity and spring tensions and loads. Unfortunately it's not by any means free. I use it extensively as I have 2 maintained seats.
Look at the SolidEdge banner on this link it is my design. And this image in the Siemens calender.
Quickly modeled suspension arm which took me no more than 10 minutes to model.
