Could I use GAP elements for modeling bush between two cylinders. How do I have to set proper patameters for gep mesh if i want it works as a cotact. Bush is puted on inner cylinder without gap and has gap with outer cylinder 5 mm. thickness of the bush 30mm. Hight of the bush 150 mm.
Is there any exapmle of using gap elements in NX Help? I did not find any one.
Can I ask why you want to use CGAP specifically? CGAP is really a bilinear spring and only really works that way in SOL 106. CGAP is also harder to generate and orient correctly.
For SOL's other than 106, the newer surface-surface contact capability would be the way to go. It's easier to set up and typically produces smoother results.
Thank you for your reply JimB. I'm triing to use gar to simulate contact between plate object. I used 106 sol and it seens good. I tryed surface-surface contactmesh. It seems work good. But there is one point to be crearify - stiffeness of the gap. Siemens recomends 3 * stiffness of connected object. How have i select proper stiffeness to simulate contact?
