Paper Title:
Application of FEM Analysis to Fault Diagnosis of Cracked Rotor
  Abstract

Based on the simple crack model and the finite element method (FEM) theorem, the corresponding dynamic equation of the cracked rotor based on FEM analysis is modeled and the numerical simulation solutions are obtained. By analyzing the dynamic characteristics of cracked rotor in diverse conditions, the properties of the un-cracked rotor and cracked rotor are discussed. A valid fault diagnosis method of cracked rotor is purposed. The method demonstrates that the cracked rotor can be identified by estimating if the swing of disk center obviously accretion and appear wave crest when rotate speed is a half critical speed of rotor shaft system.
