摘要
分析了一个由油膜轴承支承的转子系统在发生动静件碰摩时的振动特性。转子转速与不平衡量被用来作为控制参数以研究进入和离开混沌区域的各种路径以及系统的各种形式的周期、拟周期与混沌运动。结果证明碰摩转子系统在进入和离开混沌区域时可经由倍周期分岔、阵发性和拟周期路径,以及一种由周期运动直接到混沌状态的突发路径。
he vibration characteristics of a rotor system supported on oil film bearings, when rotortostator rub occurs, is analyzed. Rotating speed and unbalance are used as control parameters to investigate routes to and out of chaos, and various forms of periodic, quasiperiodic and chaotic vibrations of the system. Numerical results show that routes to and out of chaos are through perioddoubling bifurcation, intermittence, quasiperiodic route, and a kind of sudden transition route between periodic and chaotic vibrations.
