摘 要：在分析磁流变阻尼器Bouc_Wen立方修正模型及高速机车振动特点基础上，提出应用磁流变阻尼器进行机车振动控制，建立了基于磁流变阻尼器的17自由度高速机车横向半主动模型。针对模型的非线性特征，在简单模糊控制规则基础上，提出根据控制效果实时修正磁流变阻尼器输入参数的自适应模糊控制策略。在MatLab环境中进行仿真，结果表明：与被动控制、简单模糊控制相比，自适应模糊控制能有效衰减机车横向振动；在低频阶段，尤其是对乘坐舒适度影响大的5~8HZ范围内能显著提高高速机车的平稳性和乘坐舒适性。

Abstract：According to analyzing the vibration characteristic of high-speed locomotive and the Bouc-Wen model of magnetorheological damper, a vibration control method based on magnetorheological damper was put forward, and a seventeen-degree-of-freedom lateral semi-active control model of high-speed locomotive with magnetorheological damper was established. Taking into account of the nonlinear of model, a fuzzy control rule and a self-adapt control strategy to modify the input parameter of magnetorheological damper in time according to control effect was put forward. The simulation of model was studied by using MatLab. The simulation results showed that compared with the passive control and simply fuzzy control, the self-adapt fuzzy semi-active control strategy with magnetorheological damper could attenuate the vibration of the locomotive effectively and improve the ride comfort and stationarity obviously, especially in the domain of 5~8HZ which are sensitive to the human body.
