提出了考虑平移-旋转耦合振动的14自由度集总参数动力学模型，研究了面齿轮转子系统的耦合多体动力学。应用齿面方程、面齿轮啮合理论和面齿轮副的齿面接触分析，分析了面齿轮副的啮合特性。基于运动方程，采用Runge - Kutta数值方法研究了系统的耦合多体动力响应，探讨了平均载荷和间隙对系统动力响应的影响。观察到系统的跳跃现象、周期窗口、倍周期分岔和混沌行为，并观察到通过倍周期分岔运动达到混沌运动的路径。(C) 2015 Elsevier Ltd.版权所有。
A fourteen degree-of-freedom (DOE) lumped parameter dynamic model considering the coupled translation-rotation vibration is proposed and the coupled multi-body dynamics of the face geared rotor system are studied. The meshing characteristic of the face gear pair is analyzed by applying the tooth surface equation, the mesh theory of face gear and the tooth contact analysis of the face gear pair. Based on the equations of motion, the coupled multi body dynamic response of the system is investigated using the Runge - Kutta numerical method and the effects of mean load and backlash on the dynamic responses are explored. The jump phenomenon, periodic window, doubling periodic bifurcation and chaotic behavior of the system are observed and a path to chaotic motion through doubling period bifurcation motion is also observed.
