Stability of a Turbocharger Under the Influence of Cross-coupled Bearing Forces

Application ID: 55931


Cross-coupled forces present in a hydrodynamic bearing often act as a negative damping in a rotor. Near the critical speed, this may lead to uncontrolled vibration of the turbocharger causing a risk of bearing failure. In this example, the influence of the cross-coupling forces on the dynamics of the rotor is analyzed. How to reduce this vibration is also studied.

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