摘要
减振器与整车的匹配一直是汽车设计的难点,也是某微型客车厂的技术难题。以该厂的某微型车为研究对象,综合计算仿真与经验设计的优势,对该车的减振器外特性进行了优化设计。采用基于试验设计的响应面法求出减振器的最佳线性阻尼系数,然后结合国内计算反求的经验,对求得的线性阻尼系数进行分段设计,提出了新的减振器的外特性曲线方案。优化后,汽车前轴和后轴处垂直方向加速度均方根值分别降低了18.43%和10.01%,平顺性和安全性都得到了提高,说明此方法是快速可行的。
The matching of damper with full vehicle is always a hard task for vehicle design. The outer characteristics optimization of a mini-van damper is presented based on simulation and design experience. The best linear damping coefficient can be optimized by response surface method of DOE, and the final unlinear damping coefficient of the damper can be acquired based on the linear damping coefficient by separated subsection design utilizing domestic reverse design experience. After the optimization, the vertical RMS acceleration of vehicle front axle has been reduced 18.43% ,and the vertical RMS acceleration of rear axle has been reduced 10. 01%. Both the vehicle ride and safety performances have been improved ,all these show that the presented optimization method is feasible.
