摘　　要：新车具有良好的NVH性能,但随着行驶里程的增加,往往出现不可逆的NVH性能衰减现象。基于高里程汽车试验,文章提出了基于“级数”增加量和能量增加率的衰减客观评价方法,识别出高里程汽车NVH性能衰减较快的指标,结合现有数据库制定了高里程汽车相关性能指标衰减的客观及主观目标值,通过样车数据分析验证了所提方法的有效性。A new vehicle has good NVH performance,but with the increase of mileage,NVH performance often declines seriously.According to analysis of high mileage vehicle test,a NVH performance of high mileage degradation evaluation method based on"series"progressive quantity and energy increase rate is presented.Combine existing databases,objective and subjective degradation goals of NVH performance degradation are obtained.Data analysis of the sample vehicle verifies the validity of the proposed method.
