Surface Contacts

[Anonymous]

Здравствуйте, подскажите какой нужно установить контакт между shells для того, чтобы не было взаимного проникновения поверхностей? Поверхности не сварены!

Hello @Anonymous,

with shell contacts there are few things you need to take into account.

1) Shell normal, at least one of the shell surface will need the shell normal pointed so that it faces the other shell surface(s)

2) You have a gap which is caused by the thickness of the parts. To take this into account, you need to use "penetration surface offset" in the contact definition.

3) There are a few contact definitions you can use such as separation, sliding/no separation,  separation/no sliding.

4) If the contact state is changing i.e. sliding, then I suggest using nonlinear static analysis. 

John H. comments in the forum thread may also be of help.

For use by everyone, I have attached  a model with a similar setup as an example. The file was made using Inventor 2019.
