This paper discusses the design and realization of dynamic simulation platform of rolling stock on the basis of SIMPACK soft- ware. An overall architecture is proposed for rolling stock dynamic simulation platform based on the analysis of dynamic simulation characteristics. It focuses on the introduction of implementation methods of 5 modules which belongs to the platform, including vehicle modeling, simulation, post process, confidence analysis and parametric analysis. Finally, the platform is used to carry out dynamic simulation to specific type of rolling stock, and some calculation results are revealed. The platform, which improves efficiency and accu- racy of dynamic simulation, makes the usage of SIMPACK software easier, and provides strong support for research and development of rolling stock products, will have more valuable application.
