摘要
机电复合传动系统作为未来传动形式的主要发展方向,有着传递功率大,运转速度高等特点。在运行过程中转子自身由于高转速所带来的振动会与行星齿轮啮合时产生的振动相互影响,从而形成转子-行星齿轮系统耦合振动过程。建立了机电复合传动转子-行星齿轮系统耦合振动动力学模型,分析了不同转速下转子-行星齿轮系统振动特性,开展了转子-行星齿轮系统模态分析并将模态分析结果与振动特性进行了对比,通过研究转子-行星齿轮系统的振动特性,揭示了系统振动随转速升高而增大,在经过一定转速区间时振动会维持在一定水平内,随着转速继续升高,系统振动又将逐渐增大。通过研究得到了齿轮系统与驱动电机转子耦合作用下的振动特性,为机电复合传动系统高速化设计提供了理论依据。
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.
