Based on ADAMS of the analysis of vibration and noise testing of micro-vehicle rear axle

The 3D entity modeling of hypoid gears are established by using UG. In this paper, the center distance of driving gear is assembled according to the normal, left and right, the dynamic model of hypoid gear is established by ADAMS, then adding constraints and increase the driving force on it, using the way of virtual prototyping technology combined with the actual vibration testing method to study its effect to micro-vehicle rear axle vibration. Finally, through analysis of the results of dynamic simulation and comparative analysis between actual test results and the results of the dynamic simulation analysis shows that the assembly errors affect the vibration of micro-vehicle main reducer and a theoretical basis is provided.
