With running speed increases, the dynamics characteristic of railway vehicle system behaves intensively, such as, snaking motion, bifurcation problem, even digression accident. These questions effect ride comfort and run stationary. The magneto-rheological (MR) damper can continually change its state in a few milliseconds and has low energy requirement and insensitivity to the temperature and circumstance. MR dampers have turned out to be a promising device in vibration control. According to the nonlinear of MR damper and the vibration characteristic of semi-active suspension of high-speed vehicle, a seventeen-degree-of-freedom lateral semi-control model of high-speed whole vehicle with MR dampers is established. Taking into account of the vibrations of vehicle and electromagnetic interference, a novel adaptive fuzzy control strategy is put forward. The simulation results show that adaptive fuzzy control method can improve the ride comfort and restrain electromagnetic interference. The electromagnetic interference noise problems in high-speed railway vehicle system with MRD are analyzed and discussed according to EN 55022 for the first time.

带磁流变阻尼器的高速铁路车辆系统的振动控制和电磁干扰分析

随着行驶速度的提高,铁路车辆系统的动力学特性表现出强烈的行为,例如,蛇行运动,分叉问题,甚至离题事故。这些问题会影响乘坐舒适性并保持平稳运行。磁流变(MR)阻尼器可以在几毫秒内连续改变其状态,并且对能量的需求低,并且对温度和环境不敏感。事实证明,MR阻尼器在振动控制中是很有前途的设备。根据MR阻尼器的非线性和高速车辆半主动悬架的振动特性,建立了带有MR阻尼器的高速整车的十七自由度横向半控制模型。考虑到车辆的振动和电磁干扰,提出了一种新颖的自适应模糊控制策略。仿真结果表明,自适应模糊控制方法可以提高乘坐舒适性,抑制电磁干扰。首次根据EN 55022对具有MRD的高速铁路车辆系统中的电磁干扰噪声问题进行了分析和讨论。
