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.
