基于双滑模面的变轨距列车悬挂系统控制方法
Control method of suspension system of variable⁃gauge train based on double sliding surfaces approach
为了改善高速变轨距列车在不同轨距线路上的运行性能,采用基于双滑模面的滑模半主动控制方法,调节二系悬挂中空气弹簧和磁流变阻尼器的阻尼力。搭建1/4车分数阶天棚阻尼控制的滑模参考模型,设计双滑模面滑模控制器,将半主动控制方法应用于二系空气弹簧和横向磁流变阻尼器;构建变轨距列车悬挂系统半主动控制的整车联合仿真模型,分析1 435 mm/1 520 mm轨距下变轨距车辆对轨道不平顺激励的响应性能,验证整车半主动控制方法的有效性。
To enhance the operational performance of high-speed variable-gauge trains on different gauge lines,a semi-active control method based on double sliding surfaces was used to adjust the damping force of air springs and magnetorheological (MR) dampers in the secondary suspension.Based on double sliding surfaces,a quarter-vehicle fractional-order skyhook damping control reference model was established,and a double sliding surface controller was designed.The semi-active controller was applied to secondary air springs and transverse magnetorheological dampers.Finally,a joint simulation model of the whole vehicle for the variable-gauge train suspension system was constructed.The response performance to track irregularity excitation on 1 435 mm/1 520 mm gauges is analyzed to verify the effectiveness of the semi-active control method on whole vehicle.
