Abstract

Abstract: In response to the unusually obvious booming problems of the rear-wheel drive vehicles during operation, the booming tests were conducted on the entire vehicle to confirm the booming states. At the same time, the bench sweep frequency tests were performed on the transmission systems of the rear-drive vehicles to study the influences of the transmission system resonance mode on the booming vibrations. Building the multi-body dynamics model of the vehicles with the help of ADAMS software, using the model after the benchmarking to perform modal analysis calculations to study the mechanism of booming vibrations, and then a plan was formulated to improve the booming vibrations, and to verify the booming vibrations on the actual vehicles. The results show that the improvement plan for the clutch stiffness and the vibrations of the drive shafts may effectively solve the booming problems of the rear-drive vehicles.

Key words: , booming, modal analysis, booming mechanism, clutch optimization, vibration absorber

摘要： 针对某款后驱车辆在运行过程中异常明显的车内轰鸣问题，对整车进行轰鸣试验，确认轰鸣振动的状态。同时，对该后驱车辆的传动系统进行台架扫频试验，以研究传动系统共振模态对轰鸣振动的影响。借助ADAMS软件搭建整车多体动力学模型，利用对标后的模型进行模态解析计算，对轰鸣振动的发生机理进行研究，进而制定改善轰鸣振动的方案，同时在实车上进行验证。结果表明：针对离合器刚度及传动轴振动的改善方案能够有效地解决后驱车辆的轰鸣问题。
