摘要

考虑齿侧间隙、传动误差和时变啮合刚度等非线性因素，并同时考虑滑动轴承非线性油膜力和齿轮啮合力的耦合影响，建立了汇流传动齿轮-转子-轴承系统的动力学模型。从转速方面出发，研究了齿轮系统的非线性动态响应，分析了齿轮啮合力和非线性油膜力之间的耦合作用，判断了转速变化下的油膜稳定性。结果表明：随着转速变化，系统表现出周期一运动、周期二运动、拟周期运动，混沌等丰富的动力学特性，并发现了拟周期分岔通向混沌的道路；随着转速升高，非线性啮合力和非线性油膜力先后对系统振动起到主要作用；油膜振动通过半频涡动失去了稳定性。

Abstract

With the consideration of backlash, transmission error, time-varying mesh stiffness nonlinear factors in gear system, nonlinear gear mesh force and nonlinear oil film force of journal bearing were considered synchronously, the dynamic model of confluence transmission geared rotor bearing system was proposed. From rotating speed, nonlinear dynamic response of gear system was researched, coupling between nonlinear gear mesh force and nonlinear oil film force was discussed,oil film’s stability with the change of rotating speed was judged.The result indicated that with the change of rotating speed the system showed periodic one motion, periodic two motion,quasi- periodic motion and chaos motion ,the road from quasi- periodic bifurcation to chaos was founded; with the increase of rotating speed, nonlinear gear mesh force and nonlinear oil film force played a leading role in the system vibration successively;oil film vibration lost stability through half frequency whirling motion.
