Effect of Roller Bearing Clearance on Nonsynchronous Vibration of a Rotor

Application ID: 55911

Bearing clearances should be kept minimum to avoid non-synchronous vibration of a rotor. However, a tight clearance reduces the durability of the bearing. This example illustrates modeling of the vibration induced by nonlinear contact for different radial clearances.

It is shown that non-synchronous vibrations start dominating when the bearing clearance is increased.

This model example illustrates applications of this type that would nominally be built using the following products:
