Bench simulation

Hello everyone,

I would like to ask for your help regarding a problem that I encounter when using the "behavior modeling" tool.

My goal is to simulate the suspension of the vehicle, so I added in the "multibody" a spring-damper on the link which carries the shock absorber, but when I simulate, the effect of the suspension does not appear at all and it's as if the connection is blocked.

Has anyone encountered this type of problem before or has a solution or suggestion for me?

Thanks for your help
