Axisymmetric modelisation of shearpin
Axisymmetric modelisation of shearpin
(OP)
Hi,
I'm working with Patran 2004 and I'm tring to modelise an interference fit with a shearpin (simple full cylinder), a bushing and another part(the shear pin has different interference fit at the same time with both parts. I calculated the equivalent pressure on the shear pin made by the bushing, but I have a hard time to modelise the shear pin with Patran. How do you think I should do this. I was looking to make a 2D half model with symmetric boundary conditions. But I just don't know which kind of element to use.
Any help would be great!
Thanks!

btw, whilst your problem maybe be axi-symmetric, i think you're making your life difficult modelling the pin this way, but then maybe your just trying out these features in PATRAN.
this sounds like a most unusual geometry. you're joining two members with a single pin joint (which i'd usually expect to articulate somewhat) with an interference pin (that'll fight this articulation). I'd suggest that if the joint is supposed to articulate, loose the interference; or if it isn't add another fastener to prevent any movement between the members.
