传统ABS液压系统工作时存在明显的振动与噪声，研究分析了ABS液压系统振动机制，提出用伺服阀代替普通换向阀，利用MATLAB／Simulink建立基于压力反馈的PID控制结合门限值控制的ABS控制器，实现了ABS液压系统流量的连续调节与控制。建立了ABS系统AMESim模型，通过数据接口嵌入ABS控制器，实现联合仿真。分析了原ABS系统与改进后的ABS系统的压力冲击、活塞位移、速度、加速度等曲线特征，并进行了对比。试验结果表明：改进后的ABS液压系统对压力波动的抑制很好，抗冲击性能明显提高。

There are obvious vibration and noise when the conventional ABS hydraulic system is working. The vibration mecha-nism of ABS hydraulic system was analyzed and studied. It was proposed using the servo valve instead of ordinary reversing valve,and the ABS controller based on pressure feedback of PID combined with threshold was established by MATLAB/Simulink,so the continu-ously adjusted and controlled flow of ABS hydraulic system were implemented. AMESim model of the ABS system was established to achieve co-simulation by the data interface embedded in the ABS controller. The pressure shocks,piston displacement,velocity and acceleration curves of characteristics of the conventional with improved ABS systems were analyzed in comparison. The experiment shows that the pressure fluctuation is inhibited effectively in the improved ABS hydraulic system,and the impulse-resistant performance is increased obviously.
