Hi,

Any directions on how to model a shrink-fit contact model between a 3D flexible bushing and a 3D rigid shaft?

Simply changing the bushing dimension to have a different classification fit does not simulate a shrink-fit contact model.

Do you have an FE representation of your bushing or do you use the Adams bushing element?

The Adams bushing element is a force element and what you see is only a graphical representation, an icon. That has nothing to do with the forces. For the bushing, you have to work with the preloads Force and Torque as well as the stiffness values. But I don't think it is possible to properly model a shrink-fit using an Adams bushing element.

And what is the purpose? If the shaft is rigid, the crimp force doesn't do anything as it is only the resultant force that is applied to one point on the shaft.
