| Abstract: | This paper introduces the meanings of harshness and the NVH phenomena in vehicle, and summarizes the means of CAE simulation and evaluation, used to study the vehicle NVH performance.The application of the NVH performance study in the course of vehicle design is introduced emphatically, which includes FSI analysis and the building of combination model of rigid body and flexible body. With an example of the high speed shimmy in a car, the application of the NVH performance study to the improvement of vehicle comfort is discussed.Finally,the significance of vehicle NVH performance study and the important role plays in vehicle design is summarized and the prospect is forecasted. |
