摘要: 依据非线性转子动力学理论,建立了更接近实际情况的双跨滑动轴承-转子系统非线性油膜力和碰摩耦合故障的动力学模型,利用数值模拟分析了油膜力和碰摩力对转子系统耦合故障响应的影响,研究了在耦合故障的情况下,该系统的分叉与混沌运动,得到了非线性响应的Poincaré映射图、分叉图、相轨线图、轴心轨迹图和幅值谱图,发现具有非线性碰摩力及油膜力的耦合作用下转子系统的各种多周期运动和混沌运动及其演变过程。

Abstract: Based on nonlinear dynamic properties, the dynamic model of two-span sliding bear-rotor with coupling nonlinear oil and rubbing force were studied by means of numerical stimulation. The effect of oil and rubbing force on bifurcation and chaos behaviors is analyzed. Abundant dynamic behaviors of rotor were revealed by the diagrams displaying bifurcation and chaos behaviors, such as Poincaré mapping, bifurcation diagram, phase plane plots, locus trajectory, as well as amplitude spectrum. The results show that the system of bearing-rotor with nonlinear impact/rub and oil film force has abundant nolinear dynamic behaviors.
