Inventor 2014 Thin Bodies

Inventor 2014 Stress analysis

 

I have a 30' long weldment that consists of (2) MC12 x 45 and plates to make a beam and  Inventor is looking at the channel as a thin body. The channel has 3/8" plate welded down both sides to add more support. When I run it thru the simulation the channels are showing deflection but not the welded plate down the sides. The only thing I am looking for is a deflection but not sure if I am getting a true reading since the plate and the channel are not deflecting as one

 

Any ideas would be a major help

If the length to thickness ratio exceeds a certain point it will want to treat it as a Thin Body. If the welded plates have a gap for weld and fit it may exceed the boundary gap setting and not get "attached" to the rest of the body. You may need to increase this Boundary Gap setting to get it to include the plates.

Do you see bonded contacts (or connectors) that reference geometry on both the plate and channel listed in the Contacts node in the browser?

 

 

Thanks,

No I do not see a contact with the plate and the channel but all the other welds are there. What did I do wrong?

In my previous reply I said I did not have them but  I do have the bonded connections with the plate and the channel.

You may need to do increase the Tolerance in Contacts area of the Simulation Properties (Right click on Simulation in the Browser > Edit Simulation Properties). It is hard to know without looking at the model. The bonded contact should help the two components deflect together. Can you e-mail the file (nathan.chandler@autodesk.com) or share a screenshot?

 

Thanks,

I changed the Tolerance from 0.004 to 0.025 and it made no change also I email you the file.

 

Thanks
