摘要:

提出一种基于能量指标的常导高速磁浮系统平稳性评估方法。通过建立磁浮车?轨耦合动力学模型并开展多工况仿真，系统揭示轨道不平顺与系统能量传递累积特征的映射规律。最后，结合上海高速磁浮示范线轨道线形维护中的实测不平顺数据，验证了该方法的有效性。

Abstract:

In this paper， an evaluation stability assessment method based on energy indicators for high-speed maglev vehicle-track systems is proposed. By the establishment of a maglev vehicle-track coupled dynamic model and extensive multi-condition simulations， the systematic mapping between track irregularities and the system’s energy transfer accumulation characteristics is elucidated. And the method’s effectiveness is further validated using measured track irregularity data from the track geometry maintenance of the Shanghai High-speed Maglev Demonstration Line.
