Hi,

I model a compound cylinder which is rotor sheets and a shaft. They are connected with each other using shrink fit. The inner cylinder (shaft) has initial values, outer radius,(rs+delta), where delta is the interface displacement due to shrink fit. The outer cylinder has inner radius rc and outer radius, ro.

I try to simulate this process to get the stress distribution, but I don't know how to set the boundary conditions. A geometry Assembly is already done to keep the two cylinders separate.

Could you please give me some help? Or could you give me some material about the simulation of the shrink fit? I have attached my model. Any suggestion is greatly appreciated.

Best regards
Tao Liu
