摘　　要：建立电子控制可调阻尼空气悬架客车非线性刚度和非线性阻尼半车模型,通过模型仿真,在不同的道路等级、车辆载荷和行驶速度下,对悬架减振器的非线性阻尼进行优化。与典型工况时的车辆平顺性试验结果相对比,采用优化阻尼值后,客车行驶平顺性指标得到了明显改善。研究对高档客车用可调阻尼减振器的参数设计,以及电控空气悬架的控制策略确定具有重要意义。This paper establishes a 4D model of electronically-controlled damping-adjustable air suspension bus in which the non-linear damping and non-linear stiffness are taken into account. Multilevel optimization for air suspension non- linear damping of vehicle under different roads, vehicle loads and travel speeds is developed. The ride comfort is improved obviously after the optimization. This study has great significance in parameters design of damping-adjustable shock absorber on high class bus and control strategy determination of electronically-controlled air suspension.
