Vibration Analysis for Ballastless Track Bridge Based on a Hybrid Method

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 systems, 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. As an application, the vibration characteristics of the track-bridge system vertical profile assumed as random irregular were calculated and the effect of random irregularity wavelengths were analyzed.
