Dynamic analysis of rotor-cylindrical bearing system with different oil film force models

Zhaobo Chen

Abstract

To provide efficient oil film models for nonlinear dynamic analysis and design of rotor-cylindrical bearing system,the calculation precision and speed of different nonlinear oil film models are analysed.The relative error,calculation speed and nonlinear dynamic performance of practical rotor-elliptic bearing system are analyzed and compared in cases of different cylindrical bearing oil film force models.Some valuable conclusions are obtained.This supply the helpful theoretical tools for nonlinear dynamic analysis and design of rotor-elliptic bearing systems in rotating machines.
