I build a 3D model with SolidWorks and want to do the Motion Analysis on it.

The model looks like in the follow picture.

When doing the simulation, both of the two arms will be lifted up which are connected by the chain and gear. I applied the rack and pinion mate on them.

The chain is built by the chain component pattern function. The chain goes along a path which moves with the lower arm to driven the upper arm rise.

When I put the model into the Motion Analysis,  the chain won't go with the path. Therefore, the model will be really odd.

The path moves with model, but the chain still leave there.

Can anyone help?

Thank you very much.
