摘　　要：针对基于磁流变阻尼器的高速机车横向半主动悬挂系统,在分析修正的Bouc-Wen力学模型的基础上,提出了基于一般模糊控制的量化因子、比例因子的参数自适应模糊控制策略,并在SIMULINK环境中进行仿真分析,结果表明:与被动控制、一般模糊控制相比,参数自适应模糊控制能明显减小机车横向振动加速度,从而提高机车运行稳定性和乘客舒适性。For the lateral semi-active suspension system of high-speed locomotive installed with magnetorheological damper,parameter adaptive fuzzy control strategy was brought forward based on the analysis of modified Bouc-Wen mechanical model.In the strategy,some factors,such as quantification factor commonly used in general fuzzy control were still utilised.Then the suspension system was established and analyzed in the environment of SIMULINK.The results show that comparing with the strategies of passive control and general fuzzy control,parameter adaptive fuzzy control strategy can reduce the lateral vibration more obviously and make better the vehicle stability and passengers comfort.
