Vehicle drive axle end automotive driveline transmission of power, and withstand a certain load one of the main components. In engineering the car, drive axle bear more complex role in variable conditions. Therefore, the design of the drive axle, the designer only to reasonable allocation of drive axle transmission ratio, but also considering the transmission performance of the axle, so that the design of the drive axle with the best transmission performance, because the system so as to avoid driving axle the lateral vibration resonance components, torsional vibration and acceleration noise intensified drive performance problems caused by noise and vibration drive axle parts damaged or intense, ultimately drive axle early retirement, resulting in product failure. In this paper, a design and production company HR601 drive axle as the research object, the application of virtual prototyping technology, finite element method and experimental modal analysis method of drive axle existing range of issues in depth research to identify the drive axle problems The key, combined with the actual processing technology gives parts revisions. First, the application · UG three-dimensional mapping software to build the model and drive axle assembly is completed by UG and ADAMS technology to convert data between the drive axle assembly model into ADAMS, the drive axle and the ADAMS model various parameter settings. Parameter settings must be considered reflect the authenticity of the simulation, and the material parameters of the same material as the actual application. By ADAMS software to do virtual prototype simulation, to drive axle lateral vibration, acceleration noise research purposes; followed in the virtual prototype simulation based on the finite element modal theory, the drive axle parts for free modal study to find possible resonant frequency resonance phenomenon, combined with the virtual prototype simulation results, the problems of drive axle to propose amendments for the pilot study and validation provide a theoretical basis; Finally, there is the theoretical study based on a simple experimental research, through the experimental study, not only in practice, demonstration simulation technology in the drive axle design, feasibility analysis, and can serve as a driving axle production test basis, and on an experimental basis in the further improvement of test apparatus. This article focuses on the application of computer simulation and virtual prototyping Finite Element Modal theory to achieve the right drive axle transmission performance evaluation of the pros and cons, and thus make a trial study, the computer simulation and experiment together. The results show that, CAE analysis techniques can be used as the model for the design and analysis of drive axle basis, and thus extended to other types of drive axle transmission performance analysis. Application of CAE analysis technology can significantly improve the drive axle design, analysis level, shorten product design cycles, greatly reducing product development costs, and improve product competitiveness.
