基于复杂非线性数学模型的汽车减振器参数设计

Parametric design of automobile shock absorbers based on complex nonlinear mathematical models

以夏利汽车减振器为研究对象，应用减振器专用仿真软件ＳＰＳＡ－１确定了主要结构参数变化对最大、最小阻尼力及速度特性曲线形状的影响，基于ＳＰＳＡ－１软件提出了减振器的三阶段参数设计方法。

Taking the shock absorber of Xiali car as the object of study and using the special purposed emulation software SPSA-1 of shock absorber, this paper determined the influence of parametric variation of main structures upon the maximum and minimum damping forces and the shape of curves of velocity charcateristics. A method of three staged parametric design for shock absorbers is advanced based on the software SPSA-1.
