Effects of the transmission shaft on the main reducer vibration based on ADAMS and experimental demonstration

AbstractA variable axial transmission system which is composed of universal joint transmission shafts and a gear pair plays an important role in many engineering fields. However, researchers have done a lot of work in the area of gear dynamic characteristics, seldom considering the effects of universal joint shafts on the modal characteristics of gear pair system. This project takes a rear-wheel drive transmission system as a research subject. A transmission shaft-main reducer assembly virtual prototype simulation model is established by the dynamics software ADAMS; and the effects of the angle between shafts and the intermediate support stiffness on the noise and vibration characteristics of a main reducer in a rear axle are analysed. At the same time, an experiment is conducted to demonstrate the authenticity of the simulation. The result provides reference for parameters design of a drive shaft and a main reducer in a rear axle.
