摘　　要：建立了缓冲环支撑下的电磁轴承转子系统的非线性动力学模型,通过对系统稳态响应下的双参数平面图、分岔图、Poincaré映射图等图形的深入剖析,研究此类系统刚度系数变化时的非线性特性,研究结果表明:随着刚度系数的增加,系统响应由1倍周期运动逐渐向多周期及混沌运动演化,同时在混沌运动中嵌套有周期性运动窗口,当转子系统穿越临界转速区间后以逆倍化分岔的形式进入稳定的周期1运动。The nonlinear dynamic model of the magnetic levitation rotor system supported by the buffer ring is established,through the in-depth analysis of the two parameter plane diagram,bifurcation diagram,Poincarémap,the nonlinear characteristics of this kind of system when the stiffness coefficient changes are studied,the results show that with the increase of stiffness coefficient,the response of the system evolves from one time periodic motion to multi periodic and chaotic motion and the periodic motion window is nested in the chaotic motion.when the rotor system crosses the critical speed range,it enters the stable periodic 1 motion in the form of inverse doubling bifurcation.
