Researches on Vibration and Noise Reduction of CRTS-III Slab Track Arranged on Box Bridge

摘要

The CRTS-III slab track is an independent-developed track system by China. In this paper, the CRTS-III slab track-elevated box bridge coupled finite element model and boundary element model of the box bridge are firstly developed, and then the finite element/boundary element method is used to study the vibration and noise reduction of the CRT-SIII slab tracks. The research results show that the CRTS-III slab track is of well vibration and noise reduction in low frequency range.
