nThe YouTube video shows two things NOT to do when analyzing ball bearings.n#1. The model uses one Revolute Joint to hold all the balls to ground and another Revolute to hold the inner race to ground. That means the balls don't transfer the load between the inner and outer races, nor is there any radial load applied.n#2. Large Deflection was turned off! The results in the video show deformations of 5 m, which is the expected result when large rotations are applied to objects with this setting.nDon't follow that video. If you have a free choice in what to analyze, because it is a school project, or you just want to learn ANSYS, don't choose ball bearing vibrations. That is a very difficult model to build and extract meaningful engineering results.n
