Numerical simulation analysis of tri-component force coefficient of continuous beam bridge on high-speed railway
摘要
Abstract
Continuous beam bridge is a typical bridge form on high-speed railway.A CFD software was used to simulate and calculate tri-component force coefficient of continuous beam bridge on high-speed railway under different operating conditions.The effect of average wind speed attack angle,aspect ratio and the distribution of train on tri-component force coefficient of bridge section was investigated respectively.The results indicate that both wind speed and attack angle have an obvious influence on bridge' s aerostatic performance,and the increase of beam height leads to the corresponding increase of wind load,and bridge's aerostatic performance under the presence of train is less stable than that without train varies with the situation of train on bridge.关键词
