摘要:

针对某车辆行星传动系统,以发动机动态转矩为激励,采用集中参数法建立纯扭转强迫振动模型,利用拉格朗日方程建立系统微分方程并进行求解。分析了各部件在同一档位的振幅特性,得出不同部件的振动特点。研究了不同档位下行星排的振动,得出行星排在空载与受载时扭振的差异。最后对行星排啮合力波动量和动载荷系数进行计算,为行星传动系统设计和动态分析提供了依据。

Abstract:

A model was built for the forced torsional vibration excited by the dynamic torque of the engine in the vehicle multistage planetary transmission using the lumped parameter method, and the differential equations were derived by the Lagrangian equation and solved. The amplitude characteristics of the different parts in the same gear shift were analyzed, and their vibration behaviors were revealed. The vibrations of the planetary gear under different gear shifts were investigated, and the difference between the torsional vibrations of the planetary gear under load state and no-load state were obtained. The fluctuation of the meshing force of the planetary gear and the dynamic load coefficient were calculated, providing a basis for the design and the dynamic analysis of the multistage planetary transmission.

Key words: vehicle engineering, multistage planetary transmission, forced torsional vibration, dynamic response, meshing force, dynamic load coefficient
