Coupled Vibration Analysis of Vehicle-Bridge System for Jinsha River Bridge
Numerical simulation model to analyze the coupling vibration between vehicle and bridge established in this paper, upon the engineering background of Jinsha River Bridge. The finite element commercial software, ANSYS, is employed to set up the dynamic analysis model and to compute its natural vibration characteristics. Then CRH3 special refined model is built with SIMPACK, a multi-body dynamics commercial software. Considering the factors like track-rail irregularity, the dynamic performance of bridge and driving comfort level are obtained. The analysis results of coupled vibration demonstrate that bridge bears sufficient stiffness due to its satisfying vibration performance; the safety in operation of vehicle meets the requirement with the comfort index of "good". All the results not only provide reference for design, but also work as the theoretical basis for future design of similar bridges. The paper is deemed a s evidence of the priority of bridge-vehicle model by finite element method and multi-body dynamics method. The process of modeling turns to be stylized, which avoids the unnecessary programming for individual project.
