关 键 词：High-speed train suspension system lateral vibration second-order sliding mode
摘 要：As the speed of train increases, the lateral vibration of high-speed trains becomes more and more intensive. For the lateral semi-active suspension system based on magnetorheological damper, this paper proposes a control method using a second-order sliding mode to suppress the lateral vibration of high-speed trains. First, the new model of magnetorheological damper integrated high-speed train was introduced. Next, a second-order sliding mode controller is designed based on the 3-degree-of-freedom simulation model to suppress the lateral vibration of the vehicle body. Finally, the input of periodic track irregularities is analyzed. Compared with the passive system, this control strategy can improve the lateral ride comfortableness of the vehicle.
