Bearing load giving asymmetric results?

Hi there,

I'm applying a bearing load to a part and seeing odd (or at least not what I expect) results.

 

I've not posted the actual file as it is a lot larger, but I've attached a simplified version of it. Essentially it's a clevis that would have a pin through it, and is fixed at the other end.

 

When I apply the bearing load (to replicate the pin) and run the simulation, it solves OK, but the result is lop-sided. I would expect to see the same (or within a small percentage) deflection and stresses on both sides of the clevis but in this case I don't.

 

The model is perfectly symmettical, and the loading is too. Please note, there are no dimensions on the model as I just made a quick file to show the issue.

 

Is this level of variation to be expected? I've tried the same in Inventor Simulation and it gives a more symmetrical result, as does Ansys Workbench.

 

File attached shows the problem. Run the solution (should take no more than 20 to 30 seconds) and then view the model from the Front. The deflection on the right side is considerably higher than the left.

 

I just want to check if I'm missing something as to how SW may differ from other systems I've used. Thanks for any feedback.

 

Regards

 

Rory
