Research on Vehicle Road Noise Simulation Based on Virtual Proving Ground Technique

Using the virtual proving ground technique, CAE work can be put in front. Major performance problems of vehicles will be found and handled in advance to improve the research and development efficiency and reduce costs for automotive manufactures. However, this technique is relatively difficult to be implemented in NVH due to the complexity of tire modeling and other problems. Therefore, to deal with these issues, a complete simulation procedure for vehicle road noise was studied in this paper, in which PSD information of test road and CDTire model were integrated as the input of the whole vehicle simulation model successfully. The types of roads and tires, and tire mechanical parameters were compared investigated to provide useful suggestion to automotive manufacturers for NVH design.
