Bearing model for vibration analysis

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.

I need the bearing model please!

Answer 1

[Steve Miller]

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)

I have download this model, but how can I set stiffness and damping for the bearing and get the the vibration of the bearing?

I have download this model but is there any way to aply fault for beating?

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