Hi,

I have once sent my problem to this forum, however it has not been solved. This is an update to this post:

https://studentcommunity.ansys.com/thread/problem-for-modeling-the-contacts-between-the-teeth-of-two-helical-gears/

 

At first, I'd like to thank you for your useful comments. Unfortunately, my problem still persists even after doing what you suggested. I have cleared the mesh to reduce the size of the workbench file and then I have uploaded it in Google Drive. I would appreciate if you check the file to find out where I have made a mistake. Based on the rotational velocity of the small gear (6000 rpm), I have evaluated the rotation angles and the time steps. To apply the boundary condition due to the journal and thrust bearings I have used displacement and cylindrical support. A moment has also been applied to the large gear. What I am going to find is the contact pressure during one complete rotation of the small gear, however, here I have only considered 10 degrees rotation of the small gear to check if the simulation is OK, and unfortunately, I have failed.  

 

Thanks for your time and help
