Shaft and key analysis

Hello,

 

I am trying to verify the strength of a shaft and key with an applied torque of 1200Nm.

 

 

I had originally managed to get the simulation to run but the stresses predicted in the key, cross hole and radii at shaft shoulders are far FAR greater than those I have obtained using stress concentration graphs. 

 

But unfortunately now I have done something (not sure exactly what it was) that is preventing the study from running, I am getting the "large displacement" error message below. I would really appreciate it if anybody could review the fixtures/loads/mesh and give me any pointers as to mistakes I may have made.

 

 

regards,
