Rigid Body Simulation Softaware

[StressFreak]

Hi,

Does anyone know of any software for simulating rigid body movement?? I'm looking for a software to model rigid bodies as bars with specified inertia properties and relative constraints. I wouldn't like to draw the assembly like for example when using SolidWorks.

I used Matlab SimMechanics for modelling a double A-arm suspension; but I wasn´t too convinced with some results compared with what I obtained with MSC Adams.

thanks,
Diego.

see faq404-804

also MADYMO (maybe), MotionView (good luck), and that open source one from Germany (sorry, brain fade)

that open source one from Germany

are you referring to Calculix? Pre-processor is difficult, but might be usable for something as simple as a mechanism. There are other pre-processors available at a price.

If you upgrade to SW Premium you get Cosmos motion, Cosmosworks, and Routing.

Gbor - No, it's a simulation language, not FE.

Mech151,
Cosmos is a good option for simulating the final design so as to check for part's interference; but I'm looking for a more mathematical way of building a mechanism without having to draw it.

I don't know if MotionView will let me do that.

Thanks,
Diego.

Yes it will. They are pushing it as an alternative to ADAMS for mechanism simulation, since a GOLDEN marketing opportunity has opened up with the introduction of XML databases instead of text files for ADAMS.
