摘　　要：研究目的为在我国开展直线电机轨道交通的研究,因为直线电机轨道交通可改善曲线通过性能和环保状况、提高稳定性,降低土建工程造价,非常适合大中城市中等运量交通发展的需要。研究方法结合直线电机轨道交通的车辆、转向架等结构特色,建立车线耦合动力学模型,并进行大量关于线路设计参数的仿真计算。通过与软件ADAMS/Rail的计算结果进行比较,验证了模型的正确性。此外,通过传统的质点方法和行驶动力学,以缓和曲线长度为例对线路设计参数进行了计算。研究结果通过对广州市轨道交通四号线工程线路设计参数进行的仿真计算,得出了相应的线路设计参数建议值。研究结论采用新型的直线电机轨道交通方式,在一定的运行速度范围内,可以更好地通过小曲线半径和较大坡度的线路,从而降低土地拆迁及工程量,进而降低地铁造价。Research purposes：LIM track transportation lowers the civil engineering building price as well as improves curve passing function ＆ environmental protection conditions and increases stability. So it is greatly demanded for carrying medium capacity in cities. Research methods：The paper setups coupled dynamic model between vehicle and track combining the structure special features of vehicle and bogie for LIM track transportation. A large amount of simulation calculations about the line design parameters are done. The model＇s accuracy is verified by comparing the results with ADAMS/Rail. In addition, calculations through traditional method such as particle means and driving dynamics for line design parameters are also done. Transition curve＇s calculation is presented as an example in the paper. Research results：The paper presents the recommendation values of line design parameters for Guangzhou track transportation No. 4 project by the corresponding simulation calculation. Research conclusions：Within the range of certain running speed, adopting new - style LIM track transportation can reduce the amount of land pulling down and engineering to reduce the cost of subway.
