ANALYSIS OF RESPONSE OF ELASTIC ROTOR EXPERIMENTAL TABLE
弹性转子实验台的响应分析

Considering the elasticity of bearing and vibration isolating pad, this paper sets up a nonlinear rubbing model for asymmetric support rotor experimental table systems. Based on speed parameters for the bifurcation, by using the numerical integration method, the system response is obtained, and the effects of the vibration isolating pad stiffness on the system bifurcation and chaos are analyzed, through Poincar\'{e} map and auto-correlation function method. The results of system responses show that the effects are significant and the routes to chaos are mainly intermittence chaos and period doubling bifurcation. The simulation results agree well with the experimental results.
