基于正交试验的油气悬挂设计参数研究

Research on Design Parameters of Hydro Pneumatic Suspension by Orthogonal Test Method

为研究油气悬挂各个参数对其输出力的影响,引入直径比系数,推导出悬挂输出力数学模型,分析得出分别影响悬挂输出力弹性力和阻尼力的设计参数。通过仿真软件对设计变量进行正交试验,以车辆平顺性和操控安全性为目标函数,研究设计参数对悬挂的影响,确立各个参数对悬挂特性影响的大小。

Diameter ratio was introduced to transform output force expression suspension, and then parameters which were affecting Elasti can be concluded from it. A simulation based on orthogonal c force and damping test was carried out parameters which affect performance of suspension in suspension design. of hydro-pneumatic force of suspension to establish grade of
