摘　　要：分析了直线电机轮轨交通系统车辆与轨道结构的特点,针对广州地铁4号线车轨系统的特征,建立了其动态曲线通过模型。通过仿真计算得到了曲线半径、超高以及行车速度对车辆曲线通过时动力特性的影响规律。通过此项研究,为进一步探讨直线电机车辆曲线通过动力特性、优化线路设计参数以及轨道的养护维修工作打下了良好的基础。The characteristics of the vehicle and track structure of linear metro system were discussed. Then, based on the vehicle and track structure applied in Guangzhou metro line 4, a dynamic curve negotiation model was developed, and the influences of the curve radius, curve elevation and operating speed on the dynamic characteristics were obtained by computer simulation. The present work has laid the foundation for further study of the dynamic characteristics of curve negotiation, the optimization of alignment parameters and the maintenance of trackwork.
