ABSTRACT
Based on the LIM(Linear Induction Motor) track traffic system of Guangzhou, vertical dynamic coupling model of LIM vehicle-concrete slab track and their dynamic differential equations are set up, including the model of vehicle, the model of vehicle-track interaction, the model of the rail and the concrete slab track. The control technology of gap between LIM and reaction-plate and the vibration characteristics of the concrete slab track are analyzed by the dynamics simulation testing. Reasonable suggestions are put forward for the design, construction and maintenance of the slab track and the track traffic system of LIM.
