Dynamic Characteristic Analysis of a Flexible Rotor System With Fixed-point Rubbing Fault at a Wheel Edge
摘要
Abstract
Taking a single span flexible rotor system with two discs as the research object, the finite element model of the rotorbearing system was established. By simplifying one disc and its corresponding stator as two contact points and establishing pointpoint contact element to simulate rotor-stator rubbing, the rotor and stator model were coupled by contact force. By adopting the augmented Lagrangian method to deal with contact constraint conditions and coulomb friction model to simulate rotor-stator frictional characteristics, the responses of the rotor system with rubbing were analyzed under four typical cases with different rotating speeds. The simulation results were further compared with experiment results. The results show that different rotor motions appears such as period-one motion （P1）, P2, P3 and P4, with the increasing rotating speeds.关键词
