Easiest way to connect volumes
Easiest way to connect volumes
(OP)
Hi,
by importing an assembly CAD file, Ansys recognizes the different volumes. I need to connect these volumes to perform a modal analysis on it. By doing this, I want to take into account the physical properties of the connection (bolt, guideway,...). Can anybody tell me what's the easiest way to do this. The Ansys help file mentions contactpair wizard, contact elements, use of combination elements (spring damper),...
I'm a bit lost in the number of the possibilities and don't really get what's the best way to have a realistic model.
Thanks in advance,
Jeroen

RE: Easiest way to connect volumes
I would use the combin elements, but this depends on the problem you want to solve...

RE: Easiest way to connect volumes
thanks for the reaction Alex. My problem consists of the dynamic verification of a milling machine.
Can you give me some more specific information about how to use these combin elements?
thanks in advance,
