The levitation bogie of the TR-series maglev vehicle is redesigned by adding an intermediate buffer layer between the levitationbogie and the levitation module to improve the curve negotiation capacity of the high-speed maglev vehicle and reduce the vertical coupleddynamic effect of the vehicle and the track beam. As the existing TR08 maglev vehicle dynamic model has been verified by experiments, anew type of dynamic model of maglev vehicle is constructed by transplanting the functional module of TR08 model. The vehicle-elastic trackbeam coupled dynamic model and the vehicle-curved track dynamic model are established. Simulation analyses of the dynamic response ofvehicles and track beams show that: the curve negotiation capacity of the new-type maglev vehicle is better than that of TR08 type maglevvehicle; the resonance effect does not occur between the vehicle and the track beam; the vertical dynamic displacement of the track beammid-span decreases by 23% compared with the TR08 type; the redesigned levitation bogie structure and the track beam have less dynamicinteraction, indicating that the working environment of the electromagnet in the new maglev vehicle has been improved, which can effectivelyreduce the burden of electrical decoupling of the control system.

对TR系列磁浮车辆的悬浮转向架进行了重新设计，在悬浮转向架与悬浮模块之间增加了中间缓冲层，以提高高速磁浮车辆的弯道通过能力，降低车辆与轨道的垂直耦合动力效应光束。在现有TR08磁浮车辆动力学模型经过实验验证的基础上，通过移植TR08模型的功能模块，构建了一种新型的磁浮车辆动力学模型。建立了车辆-弹性轨道梁耦合动力学模型和车辆-曲线轨道动力学模型。车辆和轨道梁的动态响应仿真分析表明：新型磁浮车辆的弯道通过能力优于TR08型磁浮车辆；车辆与轨道梁之间不发生共振效应；与TR08型相比，轨道梁跨中垂向动态位移降低23%；重新设计的悬浮转向架结构与轨道梁的动态相互作用较小，表明新型磁浮车辆中电磁铁的工作环境得到了改善，可有效减轻控制系统电气解耦的负担。
