Abstract

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.
