slippage/tolerance between threaded hole and a hole on simulation

Hi Shaun,

Are you doing a thermal simulation, or are you applying a temperature load in a structural analysis? Do both materials have the same coefficient of thermal expansion?

Static simulation with thermal loads

The holes can be adjusted for a 2 1/2 thousandths of an inch which will cover a lot of stress generated. My problem is that I do not know if solidworks can account for this?

I would like solidworks simulation take into account the tolerance I have added to my axle to reduce stress concentrations. I ran 2 simulations one with both parts having the same diameter and the second one with one parte being -.022" smaller. I get the same results, same stress concentrations.

When I fix both holes (concentric) I see stresses much higher than the materials resistance which I think is because the materials do not have any tolerance to move and starts generating stresses right away.

In the study I have set global bounded to global contact bonded and contact set as no penetration between the outer and inner faces of my model. I believe that these set up bonds both parts together and denies all slippage. What connection should I use if I want slippage?

Thank you for your time

Hi Jared,

The goal of my analysis is to determine the fit needed between and axle and a bearing. they both have different temperatures and if I set them with the same opening/diameter they generate very high stresses. I would like to add a tolerance to the axle h6 -.022" smaller than the bearing diameter to reduce the stresses. I have already done this but stresses do not change, they remain exactly the same. Is there a way to reduce stresses in my analysis be doing something like this or should I take a different approach?
