Research on project and dynamic characteristics of a gauge-changeable bogie

Solving the question that rolling stock run directly through the interplot between different gauges is always a problem that is urgently being solved in international traffic. In this paper, after the application and development of the gauge changeable bogie in the world are briefly introduced, the kernel of gauge changeable technology is analyzed in detail. And a new designing project about a gauge changeable bogie whose dynamic characteristics are researched by numerical simulation is put forward.
