Paper Title:
Dynamics of Multi-Disk Rotor System with Rub-Impact Fault
  Abstract

In this paper, a multi-disk rotor system is studied. The rotor system is properly simplified and the finite element model is established. Assuming that contact region is an arc when the practical rotor-stator rub-impact fault occurs. Contact analysis and nonlinear finite element method are adopted to carry out numerical simulation of rub-impact. The results show that 1/2 fractional frequency components appear in slight rub-impact stage; 1/3 fractional frequency components appear in moderate rub-impact stage and 1/4 fractional frequency components appear in serious rub-impact stage. The research results will provide theoretical support for fault diagnosis of rub-impact.
