摘　　要：对自主开发的SUV(多功能运动车)样车和参考样车的振动、噪声进行了测试和对比分析,研究了噪声源定位和各主要噪声源对整车噪声的影响。根据研究结果提出了减振降噪措施,并在SUV样车上实施,使其车内噪声降低了2dB。Testing and comparative analysis of vehicle vibration and noise between the independently developed SUV and the reference vehicle are carried out.and noise source locating and influences of the main noise sources on vehicle noise are researched.Based on the research results.measures to reduce vibration and noise are put forward.and when they are applied to the developed SUV.the inner noise is reduced by 2 dB.
