研究了航空发动机套齿联轴器的连接刚度，推导了套齿动态啮合力计算模型，分析了随扭矩、套齿不对中和动态相对位移变化的套齿啮合力和啮合刚度。依据航空发动机套齿连接结构，建立了含套齿联轴器的三支点转子动力学模型，分析了套齿连接刚度对系统频率响应特性的影响，在考虑转轴间角度不对中的情况下，分析了套齿连接刚度对系统不对中响应的影响规律。结果发现，动态啮合力模型能够更加真实地模拟套齿连接刚度的变化，但是，当其径向啮合刚度变化不大时，其计算结果与等效刚度模型的计算结果相同，套齿角向刚度对系统动力性能影响很大，在套齿设计、装配和使用中需要重视。

The aero-engine gear coupling stiffness was studied herein ,and the coupling dynamic gearing forces were deduced ,the relationship among the gear coupling gearing forces and the torque , misalignment ,and the dynamic relative displacements was analyzed .According to aero-engine gearing structure characteristics ,a rotor dynamic model including gear coupling and the three supports was es-tablished ,and the effects of gear coupling stiffness on the system frequency response function were an-alyzed;under the conditions of considering the angle misalignment between two rotors ,the effects of gear stiffness on the misalignment responses were studied .The results show that the dynamic gearing stiffness model can simulate the gear coupling dynamic stiffness very correctly ,but the dynamic change range of the stiffness is not enough to change obviously the system dynamic characteristics , however ,the effects of the angle stiffness of gear coupling on the system vibration characteristics are very great .
