摘要：
As the main development direction of future transmission forms, the electro-mechanical transmission system has the characteristics of large transmission power and high operating speed. During operation, the vibration of the rotor caused by its high speed interact with the vibration generated by planetary gear meshing, thus forming the coupling vibration process of the rotor-planetary gear system. A coupling vibration dynamic model of rotor-planetary gear electro-mechanical transmission system is established, the vibration characteristics of the system at different speeds are analyzed, the modal analysis of the system is performed, and the results of the modal analysis are compared with the vibration characteristics. By studying the vibration characteristics of the rotor-planetary gear system, it is revealed that system vibration increases with the speed. When passing a certain speed range, the vibration remains at a certain level. As the speed continues to rise, system vibration gradually increases. The vibration characteristics under the coupling effect of the gear system and the drive motor rotor are obtained, which provides a theoretical basis for the high-speed design of the electro-mechanical transmission system. © 2023 China Ordnance Society.
