Vibration Analysis for Ballastless Track Bridge Based on a Hybrid Method
Publication: ICTE 2013: Safety, Speediness, Intelligence, Low-Carbon, Innovation
Abstract
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. 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 wavelength were analyzed.
