Restricting Motion in Mechanica 2001

[sunilkoshy]

Hi


How can I restrict the motion of a part when it comes in contact with another part.


I tried Contact Region, but I'm getting the error showing that "there is an edge contact, which is not supported by Mechanica"


May be I went wrong in some definition.

Can anyone help me in this matter.

Regards


Sunil

Sunil,


Mechanica Motion uses Hertzian contact while calculation impact analysis. That means that the two surfaces in contact must be round. That said at leas one of the surfaces must be round and the other one a plane or both must be round. What you can do if this is not the case in your model is to create a dummy round surface in one of the parts and then apply the contact region to that surface instead of the regular surfaces you were using. I hope this info helps you to resolve the problem.

Hi Luis


Thankyou. I tried creating both the condition mentioned by you, i.e 1 flat & 1 round, 2 rounds. In both the cases I'm getting the message that there is an edge contact...

Sunil,


Could you supply a picture of the two parts you are trying to use for the motion contact analysis? Or May be you can post the model.
