Abstract

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
