摘要

油气悬架因其变刚度、变阻尼特性在重型车上得到了广泛的应用，但常规的被动式油气悬架不能根据路面条件进行实时调整以满足整车平顺性的要求。本文在常规油气悬架的基础上提出了一种主动控制方法，首先在AMSEim中建立油气弹簧的数学模型，并通过试验验证模型的正确性，然后建立1/4主动油气悬架的动力学方程，采用fuzzy-pid 算法完成对电液伺服阀的控制，从而实现对主动油气悬架输出力的控制。通过AMESim和MATLAB/Simulink联合仿真表明，该主动油气悬架的性能明显得到改善，与被动悬架相比降低了车身加速度，提高了车辆的平顺性。

Abstract

Because of the variable stiffness and damping characteristics of the hydro-pneumatic suspension, it has been widely used in heavy vehicles. But the conventional hydro-pneumatic suspension cannot adjust to fulfill the requirements of vehicle ride comfort based on the road conditions. In this paper, an active control method is proposed based on conventional hydro-pneumatic suspension. After modeling and experimental validation of the hydro-pneumatic spring, a quarter dynamic model of vehicle active hydro-pneumatic suspension is established and then using fuzzy-pid to control the active hydro-pneumatic suspension. It is co-simulated with AMESim and MATLAB. The simulation results show that the vehicle acceleration is reduced obviously and the ride comfort characteristics are improved comparing with passive suspension.
