Abstract: In order to realize the analysis and optimization of NVH performance of automobile drive axle, the process and method of NVH performance analysis and optimization of drive axle are established. The methods of finite element, vibration response, acoustic simulation and topology optimization analysis used in the analysis process are comprehensively studied. Appropriate analysis methods, calculation methods and analysis software are selected. The noise problem of a bus in 60~65 km/h acceleration driving condition is analyzed and optimized as an example. Finally, the NVH test of the optimized driving axle is carried out to verify the validity of the established analysis process and method
