Hello, everyone!<\/p>\n

I searched through references and this forum regarding fatigue analysis in shafts subjected to torques caused by gears, but I could only find analyses on torsion or bending of shafts.<\/p>\n

Due to my lack of experience with Ansys in simulations involving shafts, I also had doubts about the “Remote Displacement” that defines the boundary conditions of the problem. I found a very good explanation at this link (\/forum\/forums\/topic\/how-can-i-simulate-this-shaft-from-shigleys-book\/)  for the same problem, but I still can’t fully grasp it.<\/p>\n

What I need is to define the Von-Mises stress and safety factor of this shaft with fatigue life.<\/p>\n

In summary, I have two main questions:<\/p>\n

1 – Can I replace the application of these forces with a torque?<\/p>\n

2 – How does the application of “remote displacement” work in detail for this project?<\/p>\n

This is the result of my simulation so far:<\/strong><\/p>\n
