摘要
以汽车车身垂直加速度作为评价汽车减振性能的指标,同时考察影响汽车操纵稳定性的指标。针对普通乘用车的乘坐舒适性和操纵稳定性,对汽车减振系统动态特性进行研究。基于乘用车车身加速度、减振系统动挠度、车轮与路面间动载的幅频特性,对乘用车减振性能进行对比分析,指出研究动态性能可变的减振系统是乘用车振动性能改进的重要措施。
Vertical vibration acceleration of sedan＇s body is taken as the evaluation index of the damping performance,and the indexes for vehicle handling and stability are studied too.The dynamic performance of the damping system of the sedan is studied for improving its riding comfort and handling stability.Based on the amplitude-frequency characteristics of the body acceleration of the sedan,the dynamic deflection of damping system,and the dynamic load between the wheel and road,the damping performance of the sedan is analyzed.It is indicated that the study on variable damping system is an important measure for improving the vibration performance of sedans.
