Abstract
The light rail vehicle with linear Induction Motor (LIM) bogie, which is a new type of urban rail traffic tool, has the advantages of low costs, wide applicability, low noise, simple maintenance and better behavior on climbing and curving. This vehicle is not driven by the adhesion force between the wheel and rail, and is driven by the electromagnetic force between LIM and reaction plate, while supported and guided by wheel and rail. In this paper, three different types of suspension and their characteristic are discussed with considering the interactions both between wheel and rail and between LIM and reaction plate. A nonlinear mathematical model of the vehicle with LIM bogie is set up by using the software SIMPACK, and the mechanical electric model is also set up on Simulink roof. Then the running behavior of the LIM vehicle is simulated, and the influence of suspension on the vehicle dynamic performance is investigated.
