摘　　要：从车辆构造特点出发,建立电磁悬浮(EMS)型高速磁浮车辆悬浮架、悬浮电磁铁链式结构动力学模型,并引入基于状态观测器的悬浮控制算法。结合反映道岔结构特征及动力特性的有限元模型,建立车-岔系统动力响应分析模型。仿真结果表明,所提出精细化模型的数值模拟结果与实测数据较为接近。在此基础上,开展了单节和多节编组列车在静悬以及低速和高速通过道岔等多种工况下的仿真试验,分析了不同影响因素下高速磁浮车-岔系统振动特征。仿真和实测结果表明,明确车-岔-悬浮控制之间的参数匹配关系是揭示车-岔相互作用机理的前提和关键。Based on the structural characteristics of vehicles, a dynamical model of suspension frame and suspension magnet chain structure of electromagnetic suspension(EMS) high-speed maglev vehicle was established, and the suspension control algorithm based on state observer was introduced to simulate the active suspension control. Combining with the finite element model reflecting the unique structural and dynamical characteristics of maglev turnout, a numerical analysis model of maglev vehicle-turnout system was established. It is shown that simulation results are close to the in-situ measurements. On this basis, the dynamic response analysis of vehicle-turnout in single-and multi-car formation at low, medium and highspeed running through the turnout was carried out. Both numerical and experimental results show that defining the parameter matching relation of the vehicle-turnoutsuspension control system is the premise and key to reveal the interaction mechanism between the maglev vehicle and turnout.
