摘　　要：针对行星齿轮箱振动响应,建立考虑齿圈螺栓约束的行星齿轮箱振动信号模型。基于集总参数模型,求解各部件的振动位移,计算内齿轮副的啮合力;将带螺栓约束的齿圈简化为欧拉-伯努利梁,通过求解梁的振动建立齿圈上任意点的振动信号。基于所建立的信号模型,分析振动信号的传输机制、振幅调制和重叠现象,以及螺栓约束对齿轮箱振动的影响,最后通过实验验证了新方法的合理性。该新模型不需要考虑所选振动部件的窗函数和权值,可以有效避免人为干扰,具有较强的通用性和适用性。Aiming at the vibration response of planetary gearbox,the vibration signal model of planetary gearbox considering the constraint of ring gear bolt was established.Based on the lumped parameter model,the vibration displacement of each component was solved,and the meshing force of the internal gear pair was calculated.Then the ring gear with bolt constraint was simplified to Euler-Bernoulli beam,and the vibration signal of any point on the ring gear was established by solving the vibration of the beam.Based on the established signal model,the transmission mechanism of vibration signal,amplitude modulation and overlap phenomenon,and the influence of bolt constraint on gearbox vibration were analyzed.Finally,the rationality of the new method was verified by experiments.The new model does not need to consider the window function and weight of the selected vibration components,which can effectively avoid human interference,and has strong universality and applicability.
