摘要：
A translation-rotation coupled nonlinear vibration differential equation for planetary gear sets was built based on the gear system dynamics. The natural frequencies and vibration shapes of the system were calculated and the distribution of natural frequencies and the characteristics of vibration shapes were presented. Taking into account the direct proportional relationship between the internal meshing excitation and rotating speed of the system, the sweep sine excitation was made in use to simulate the internal meshing, excitation and the corresponding vibration response was obtained by solving the dynamic differential equation. It is found there is a specific mapping relation between the excitation and response. It is also found that the internal meshing excitation has a smaller influence on the low(1~5)and high(16~18)natural frequencies, but the influence of external meshing increases along with the increase of the order of natural frequency and there is a larger influence on the sun gear rotational modes of high natural frequencies. Both the internal and external meshings have significant influence on the planetary gear rotational modes of intermediate natural frequencies(6~15). The study gives a foundation for the vibration reduction in the design of planetary gears sets. © 2017, Editorial Office of Journal of Vibration and Shock. All right reserved.
