The embodiment of the invention relates to a hydraulic suspension transverse vibration reduction system for a maglev vehicle and a control method thereof, the hydraulic suspension transverse vibration reduction system for the maglev vehicle comprises a plurality of hydraulic cylinders, each hydraulic cylinder corresponds to a suspension frame of the maglev vehicle, the upper ends of the hydraulic cylinders are connected with a vehicle body, and the lower ends of the hydraulic cylinders are connected with the suspension frames; each hydraulic cylinder is divided into an upper liquid chamber and a lower liquid chamber by a piston in the hydraulic cylinder; the upper liquid chambers are sequentially communicated in parallel to form a first hydraulic branch, and the lower liquid chambers are sequentially communicated in parallel to form a second hydraulic branch. The energy accumulators are arranged on the first hydraulic branch and the second hydraulic branch correspondingly and provide rigidity for transverse movement of the vehicle body. The electromagnetic valve is arranged on a communicating branch of the first hydraulic branch and the second hydraulic branch; when the maglev vehicle is in a straight line, the electromagnetic valve is closed, and the system provides rigidity and damping for transverse movement of the vehicle body; when the maglev vehicle is in a curve line, the electromagnetic valve is opened, the communication branch is communicated, the rigidity of transverse movement of the vehicle body is zero, and the system provides damping.
本发明实施例涉及一种磁悬浮车用液压悬挂横向减振系统及其控制方法,磁悬浮车用液压悬挂横向减振系统包括:多个液压缸,每个液压缸对应磁悬浮车的一个悬浮架,其中,液压缸的上端连接车体,下端连接悬浮架;每个液压缸被液压缸中的活塞分隔为上液室和下液室;多个上液室依次平行连通形成第一液压支路,多个下液室依次平行连通形成第二液压支路;蓄能器分别设置在第一液压支路和第二液压支路上,提供车体横向运动的刚度;电磁阀设置在第一液压支路和第二液压支路的连通支路上;磁悬浮车处于直线线路时电磁阀关闭,本系统提供车体横向运动的刚度和阻尼;磁悬浮车处于曲线线路时电磁阀打开,连通支路连通,车体横向运动的刚度为零,本系统提供阻尼。
