rigid body mechanism

Hi,

Is it possible to simulate a rigid body mechanism similar to rigid MBD? Bodies and joints have to be perfectly rigid to avoid jamming/binding closed kinematic chain mechanisms. Attached is the sample containing RBODY elements connected through revolute Kjoint2, which is defined with stiffness so there is some unwanted compliance. Any ideas or workarounds to carry out kinematic studies in Radioss?

Hi,

For simulating kinematic linkage type simulations it is better to use MBD.

But this simulation looks good. Can you try with a lower stiffness value?

Hi George,

thanks for the tip. I will try to simulate with flexible body in Motionsolve.
