【Abstract】 With the development of Chinese railways, it is important to study the dynamics of locomotives and rolling stocks during the process of their development and design. The simulation system of vehicle-track coupling dynamics and engineering applications in the modem design of new locomotives in Chinese railway are introduced in this paper. Firstly, the paper describes basic theory and structure of the simulation system, the key technical and the method how to be applied in engineering, technology of three dimensions and visualization and a visualization platform established on self-adaptive to the varying model parameters in the system, strong value in engineering application of this simulation system. Secondly, validation of calculation results is displayed briefly on the basis of recent experiments in China, and the comparison results show that it is good correlation between simulation and experiment. Thirdly, effect of parameters of railway structure on dynamics performance of locomotives and rolling stocks and comparison on the calculation results between coupling theory and traditional theory are discussed, the results show that it is necessary to carry on the research of coupling dynamics. At last, applications in the design of new locomotives are presented, including the 200 km/h electric locomotive "Tiansuo", the speed-raised locomotive SS_7E for passenger transport, and the speed-raised locomotive for freight transport. Results show very good prospect of applications of the simulation system in modern railway vehicle design domain.更多还原
