| 摘 要： | 在考虑齿轮时变啮合刚度的情况下，建立了齿轮耦合的转子－轴承系统的非线性动力学模型，用数值仿真法研究系统的稳态不平衡响应时发现，由于齿轮时变啮合刚度的影响。在系统响应中，不但会出现对应于啮合频率的响应分量，而且在某种条件下，该分量甚至超过基频分量；一个转子上的不平衡质量不仅会对本身产生激励，而且也会对其它转子产生激励。

| Abstract: | Considering the time varying meshing stiffness of gear pair, the nonlinear dynamic model of a geared rotor bearing system is established. By employing numeric simulation, the stable response of the system to mass unbalance is obtained. Because of the time varying meshing stiffness, in the response of the system, there exists the component corresponding to meshing frequency, which is more than that corresponding to fundamental frequency in some condition. The larger dynamic loads and separation phenomenon are also caused by it. The mass unbalance on one rotor not only makes itself, but other rotor to vibrate. |
