A hybrid method combining finite element method (FEM) and statistical energy analysis (SEA) was recently presented for predicting the steady-state response of vibro-acoustic systems. Based on the structural characteristics of vehicle-CRTS II ballastless track-bridge system, the hybrid method of vehicle-track-bridge elements was presented. Using finite element method and Hamilton Theory, the coupled equation of vehicle-track-bridge can be established. Computational software is coded with Matlab. As an application, the vibration characteristics of the track-bridge system vertical profile assumed as random irregularity were calculated and the effect of random irregularity wavelength was analyzed. The computational results show that (1) The changes of the rail random irregularity wavelength have little influences on vertical displacement of track structure. (2) While it has very significant influences on vertical wheel/rail contact forces, and vertical acceleration amplitude of rail and slab, and the influenc...
