Contact pairs or simply boolean union??

Please login with a confirmed email address before reporting spam

Hello,

My model involves vibrating a component via a clamp that it is attached to. My question is, do I need to define contact pairs for the surfaces of the clamp and component that are touching? All I want is to know that the component is rigidly bonded or attached to the clamp. How can I verify this rigid attachment?

Your suggestions will be very much appreciated.

Thanks

Contact pairs are used to ensure that two surfaces that come into contact do not penetrate each other. So my answer would be yes...

This is done by definitions>contact pair....the source boundaries are the rigid parts of clamp, destination boundaries the component.Then you have to add contact pairs in the physics part.

having said that I had to deal with contact pairs a while ago and found them diificult to implement correctly. Could you get back to me if you manage to do this?

Hope this helps,

Chris
