Hello, I'm developing a project for my master's degree and I'm working with mechanical models for my research and I have a question:
Is there a bearing model whose vibrations can be obtained knowing the speed of the axis that rests on it?
Thanks for all.

You can find a model of a ball bearing in the Simscape Multibody Contact Forces Library.

  1. Download the submission
  2. Run startup_Contact_Forces.m
  3. Navigate to the ball bearing example (see below)

Another approach could be to set bearing stiffness and damping as functions of rotor speed or constants in the Driveline Flexible Shaft block:
