How to limit the min and max length of Cylindrical joint block?(sms​cape->mult​ibody->cyl​indrical joint)

I want to limit the distance of two body which are connected by cylindrical joint.Because I need the strike force of two body,but they are through each other and cannot contact with each other in simulink simulation.So I need a way to limit the max and min distance of two body.

I recommend you look at the Simscape Multibody Multiphysics Library. It shows how to solve this exact problem on a Prismatic Joint. For a Cylindrical Joint, you need to make sure you enable the connection using the Pz degree of freedom.

Thank you,Miller. I had run the multibody demo "sm_ssci_hydraulic_lift_trsn",It's hard to understand.

This is a min state.

This is a max state.

rod1_RIGID is body1,and shell1_RIGID is body2.I need face1 and face2 strike,and get the strike force.
