In this paper, a space model for analyzing track structure is established by means of finite element method, in which rails, ties, rail clips and pads, ballast and roadbed are considered as a whole system. The action of locomotive and rolling stocks on track can be obtained from wheel set model. In the wheel set model, only sprung mass are concerned and the masses of locomotive or rolling stocks are uniformly distributed to each wheel set. The track structure is treated as a double elastic beam. In the process of performing space analysis of track structure of high speed railway, firstly the load spectrum changing with the time and acting on the ties are derived by using the wheel set model. Then the load spectrum is entered to the model of space analysis of track structure as input data. Finally analyses of dynamic response of track structure for TGV at different speeds are performed.
