摘　　要：针对某前置后驱车辆存在的轰鸣振动以及换挡冲击问题,进行整车试验分析,发现在发动机转速为1 600r/min、2 700 r/min时的轰鸣振动较为明显,换挡冲击的振动频率在10 Hz之内。借助ADAMS软件搭建整车虚拟样机模型,利用ADAMS/Vibration模块进行模态解析计算,结果表明:转速为1 600 r/min时的轰鸣振动的影响因素为离合器回转刚度,换挡冲击的影响因素为飞轮惯性质量。因此对实车的双质量飞轮惯性质量以及刚度进行优化,同时在实车上进行验证,结果显示该改进方案能够同时解决轰鸣振动以及换挡冲击问题。The booming vibration and shift shock problems of the front-set rear-drive vehicles are studied. The vehicle test analysis shows that the booming vibration is more obvious when the engine speed is at 1 600 r/min or 2 700 r/min, and the vibration frequency of shift shock is below 10 Hz. With the aid of ADAMS software, a virtual prototype model of the vehicle is built and the modals of the model are calculated using ADAMS/Vibration module. The results show that at the speed of 1 600 r/min the influencing factor of the booming vibration is the rotation stiffness of the clutch and the influencing factor of the shift shock is the inertial mass of the flywheel. Therefore, the inertial mass and stiffness of the dual-mass flywheel of the real vehicle are optimized and verified on the real vehicle. The results show that the improved solution scheme can simultaneously solve the problems of booming vibration and shift shock.
