With the construction of high-speed railway worldwide, research on train-track-bridge dynamic analysis is becoming a focus of increasing interest. In this paper, the rolling stock were regarded as the multiple rigid system, and all kinds of movements of the car body, bogies and wheel-set and several of non-linear factors in vehicle suspension system were fully considered. A detailed ballast track model and dynamic equations were established. The motion equation of a bridge was established by the finite element method. The equations of the system were solved with the help of numerical method. A simply supported beam with a span of 24 m on the line of Qinhuangdao-Shenyang Special Passenger Railway was evaluated with the help of the programs we have complied. The theoretical results highly conform to the measured values. From this, we concluded that the theory of train-track-bridge coupling system is right and the programs are feasible.
