The dynamic model of Jeffcott rotor system with rubbing fault based on two rigidity supports was built.Both thought of shooting method and Runge-Kutta method were combined,and nonlinear dynamic behaviors of rotor system caused by rubbing fault were studied.Some typical rotor shaft locus,time history,amplitude spectra,and Poincaré mapping section of rotor system response and so on were obtained from numerical simulation,the effects of rotor system parameters,such as frequency ratio and eccentricity mass,on rotor system behaviors was analyzed,from which,the complicated dynamic behaviors of periods,quasi-periods and chaos in this nonlinear vibration system were investigated.The conclusions have some significance to identify and diagnose the rubbing fault.
