As the research object to a new type of the minibus drive axle NVH performance, vehicle noise and vibration testing to measure the noise level of the drive axle and modal finite element analysis using ABAQUS software. Corresponding improvement measures for the natural frequency of the pinion gear noise and drive axle, and experimental verification in the vehicle. The test results show that the theoretical analysis calculations and effective improvement measures, providing a reference for late drive axle design and improvement.
