Bolt Connector in Thermal Study

Question asked by Peter Biggert on Mar 27, 2009

I bolt two parts together using bolt connectors. If I do a thermal study the forces in the bolts go through the roof. Apparantly, because they are still at the stress free temperature while everything else has expanded with temperature. In real life the bolts would heat up too.

Fine, I could model the bolts. But the old method to preload them was to specify a temperature difference between the bolts and the part. In a thermal study, I am not sure how to get the initial preload and still have the bolts reach a steady state temperature with their surroundings.

Does anyone have suggestions on how I can perfom a static thermal study on parts bolted together?
