Study on Multi-Body Dynamics Simulation of the Driving Shafts and Driving Axle Systesm of the Minibus Based on ADAMS


Firstly, the model of the leaf spring, which supports the rear driving axle of minibus, was established by using three-link leaf spring model method. In multi-body dynamic simulation software ADAMS, this spring model was employed to calculate its stiffness and guiding characteristics. Then the software, SOLIDWORKS, was integrated to establish the model, including the combined stiff and flexible parts from the gearbox output shaft to the half axle of the driving axle and the rear suspension. With this model, Kinematics and dynamics analysis were performed. The effects of equivalent shaft angle on the vibration characteristics of various important components of the system were also investigated. The results show that when the angles between cross axes in the two universal joints are not equal it causes severe vibration in the important components among the driving shaft-driving axle system. The simulation with high reliability provides a dynamic ride vehicle model for follow-up study.
