In order to explore the potential advantages of HTS maglev vehicles, the dynamic response of HTS maglev vehicle-bridge coupling system model under different speeds and track beam spans is calculated by using Universal Mechanism (UM) software, which is further compared with two existing high-speed train systems, the high-speed EMS vehicle and wheel-rail vehicle. Before establishing the dynamic model, first a simplified mathematical model of levitation force of HTS maglev is extracted based on the experimental results of three YBCO bulks on a Halbach permanent magnet guideway (PMG). The results of simulation show that the HTS maglev vehicle can fully meet the requirements of current high-speed railway operation index on the acceleration of car body and its influence on track beam. The comparisons show that HTS maglev vehicle has some advantages over high-speed EMS vehicle and wheel-rail high-speed vehicle, especially in the acceleration of the car body and the impact on the track beam under high-speed operation. This makes a better understanding of the dynamic performance of HTS maglev vehicle, and provides an effective reference for the selection of high-speed railway system types and related indicators in the future.

为挖掘HTS磁浮车辆的潜在优势，利用Universal Mechanism（UM）软件计算了HTS磁浮车桥耦合系统模型在不同速度和轨道梁跨度下的动力响应，并与现有的两种高-高速列车系统、高速EMS车辆和轮轨车辆。在建立动力学模型之前，首先基于三个 YBCO 块体在 Halbach 永磁导轨 (PMG) 上的实验结果，提取了 HTS 磁悬浮悬浮力的简化数学模型。仿真结果表明，HTS磁悬浮车辆完全满足当前高速铁路运行指标对车体加速度及其对轨道梁影响的要求。对比表明，HTS磁悬浮车辆相对于高速EMS车辆和轮轨高速车辆具有一定的优势，尤其是在高速运行下的车身加速度和对轨道梁的冲击方面。这样可以更好地了解HTS磁浮车辆的动态性能，为今后高速铁路系统类型及相关指标的选择提供有效参考。
