摘　　要：针对车辆噪声振动舒适性的问题,基于某后驱电动车型噪声振动舒适性性能研究,经试验确认后排轰鸣声由于传动系统产生弯曲模态引起。通过在后桥鼻锥位置增加动力吸振器,能有效降低共振处的幅值,进而改善车内后排轰鸣声。Aiming at the problem of vehicle noise,vibration and harshness,based on the study of the noise,vibration and harshness performance of a rear-drive electric vehicle,the test confirmed that the rear booming noise is caused by the transmission system bending resonance.Increasing the mass damper in the position of the rear axle can effectively reduce the amplitude of the vibration,improving rear booming noise in the vehicle.

关 键 词：传动系统 轰鸣声 动力吸振器
