Abstract

A model of monolithic roadbed track system was established based on the finite element method (FEM). Modal and harmonic response analysis are carried out. Vibration features and dynamic response of the system are analyzed. The effect of different parameters, including rail fastenings, sleepers and elastic pads, on the riding comfort and the transmission rate of the track system is calculated. The results are presented and analyzed with the riding comfort and the transmission rate as the reference standards.
