Vehicle chassis usually adopts variable speed axial transmission system composed of universal joint transmission shaft and gear pair. The vibration, impact and energy loss are related to the efficiency of power transmission and the safety performance of equipment. Since variable shaft transmission system is the key component of vehicle chassis, vibration and noise reduction is the inevitable way to improve vehicle quality, energy conservation and environmental protection. However, researchers have done a lot of work on the dynamic characteristics of gears, rarely considering the influence of cardan shaft on the modal characteristics of gear pair system. Taking the rear wheel drive system of a vehicle chassis as the research object, the virtual prototype simulation model of the transmission shaft main reducer assembly is established by using the dynamics software ADAMS, and the influence of the stiffness of the shaft and the intermediate support on the noise and vibration characteristics of the rear axle main reducer is analyzed. At the same time, the accuracy of the simulation results is verified by experiments, which provides a reference for the parameter design of the drive shaft and the rear axle final drive.
