Dynamic Simulation

[Konstruktor]

Hello!

I have a crane model here. I want to use FEA to calculate stresses and safety factors for the upper beams and do it through a dynamic simulation. The problem is that it seems that I can use in simulation only components that belong to the main assembly but not to some of subassemblys!? Is that true? Always when I try to pick one of them IV tells me that: "The part is in a subassembly"... or similar. How to overcome this? See my simple model:

You might try promoting all the individual components of the assemblies to the top level. In the assembly, expand the assembly in the tree. Right-click on a component of the assembly, highlight 'Component' and select 'Promote'. You'll lose all of your constraints, that's the bad part.

I don't think adaptivity and flexibility have anything to do with it, but I stand to be corrected.

The FEA solver "bundled" in Inventor Pro only analyzes parts, not assemblies.

If your assembly has no gaps between parts, you could make a derived component, which saves as an ipt, then perform your FEA on that.

The analysis will be assuming fully bonded parts at the interfaces.

Inventor Pro does not provide surface to surface contact modeling.

Hope this helps.

Yes, flexible assembly allows later to pick parts for converting to FEA. (But unfortunately there is really no way for part analyze - like btrueblood mentioned :-( ) But you can this capability buy from ANSYS at any time
