Simple analysis on Inventor 2008

Simple analysis on Inventor 2008

Simple analysis on Inventor 2008

(OP)
Hi,
I'm trying to analyze the attached part in AutoDesk Inventor (2008) and cant decide upon the best way to constrain it. It's a clamp that gets screwed to a surface and then applies a force towards that surface via a screw.

I'm applying a force to the red surface in the pic, but how to simulate the mounting screw in the counter-bore, holding the clamp to the surface? It seems I should use the annular c'bore surface but I'd also need a constraint on the mounting surface? I don;t really want to simulate 'gluing' the part to the surface..

FYI, Inventor 2008 'incorporates FEA technology from Ansys for part level stress analysis'.

I can give more details on the constraint/load types available if needed.
 

RE: Simple analysis on Inventor 2008

there's going to be a bolt down the hole, compressing the bottom face, yes?

i'd support the bottom surface, certainly out-of-plane, but i think Inventor will only allow you to fully contrain each node on the bottom has (rather than just the out-of-plane direction.

and i'd apply a force on the bottom face of the counter-bore, representing the load from the bolt.  so there should be a bunch of compression in the fitting before you apply the load, F.
