| 摘 要： | 分析了空气弹簧的非线性刚度特性，建立了1／4车辆非线性模型。依据设定的弹簧目标刚度，制定了以50km／h和70km／h为阈值的控制策略。通过在不同车速和路面条件下仿真，验证了调节空气悬架的刚度和阻尼可以起到降低车身加速度的均方根值等效果，使车辆平顺性得到较好的控制。

| Abstract: | The nonlinear stiffness characteristics of air spring were analyzed, and a quarter vehicle nonlinear model was established. The control strategy was established that the velocity threshold was 50 and 70 km/h on the basis of the spring stiffness. It was verified that the root mean square of bodywork acceleration etc. can be reduced via adjusting the stiffness and damping of air suspension at different speeds and road conditions. It can obtain better vehicle ride comfort. |
