摘　　要：应用桥梁动力学、车辆动力学和电磁相互作用原理建立了高速常导磁浮交通车-梁-墩体系动力分析模型,利用数值积分求解了大规模非线性耦合动力方程。在此基础上结合具体线路条件进行了车线耦合动力学检算,得到了曲线地段车辆及梁墩体系动力响应基本规律。该部分的研究为制订合理的高速磁浮线路设计标准提供了理论依据。A vehicle-guideway-pier dynamic model of high-speed maglev system was established based on bridge dynamics, car dynamics and electromagnetic interaction between vehicle and guideway girder. The large nonlinear coupling dynamic equations were solved by numerical integration. Vehicle-guideway dynamic checking computations under concrete line conditions were done and some basic laws of dynamic response of vehicle-guideway-pier system moving on curves were gained. The study lays down a theoretical foundation for line design criterions in high-speed maglev system.
