摘要/Abstract

摘要： 为揭示行星变速机构内部激励与振动特性的映射关系，通过设计行星变速机构振动测试方案，建立了行星变速机构振动加速度测试系统，并进行了典型挡位2 500 r/min行星变速机构振动特性的测试与分析。结果表明：行星变速机构振动的均方根（RMS）值与测点的位置相关联，测点位置在行星齿轮啮合位置，其振动幅值较大；随着转矩增大，其振动RMS值也增大。行星变速机构的频谱分析结果表明，其振动能量主要集中于行星齿轮啮合的啮合频率及倍频，且轴向的频谱和径向上的频谱比较相似。通过行星变速机构振动RMS的测定和频谱值的分析，得到了各位置啮合振动的最大幅值。本研究对行星变速机构的优化设计具有一定的参考价值。

Abstract: In order to reveal the mapping relationship between internal excitation and vibration characteristics of planetary transmission mechanism, a vibration acceleration measurement system of planetary transmission mechanism was established by designing a vibration test scheme, and the vibration characteristics of typical gearshift 2 500 r/min planetary transmission mechanism were measured and analyzed. The results show that the vibration root mean square (RMS) value of planetary transmission mechanism is correlated with the position of measuring point. The measuring point is in the meshing position of planetary gear, and its vibration amplitude is larger. The vibration RMS value increases with the increase in the torque. The frequency spectrum analysis results show that the vibration energy mainly concentrates on the meshing frequency and multiple frequencies of planetary gears, and the axial frequency spectrum is similar to the radial frequency spectrum. The maximum amplitude of meshing vibration is obtained by measuring the vibration of planetary transmission mechanism and analyzing its frequency spectrum. Key
