Influence of Bearing Defects on Dynamical Behavior of An Elastic Shaft

Influence of Bearing Defects on Dynamical Behavior of An Elastic Shaft

A study of an elastic rotor supported by two defect bearings is presented. The bearing behavior must be considered non-linear because of the defect effects. The rotor is modelled by typical beam finite element including effects such as gyroscopic effect. The dynamic behavior is analysed using an uns...
