摘要

摘要: 基于三维定常N-S方程和k-ε双方程湍流模型, 采用有限体积法模拟了高速铁路桥梁上透风式挡风墙高度对列车气动性能的影响, 分析了挡风墙后列车倾覆力矩、接触网处风速与挡风墙高度之间的关系, 结合风洞试验验证了数值方法的正确性。分析结果表明: 安装挡风墙后, 随着挡风墙高度的增加, 当量横向力系数、倾覆力矩系数绝对值迅速减小; 在相同挡风墙高度下, 背风线列车当量升力系数约为迎风线列车的1/2;无挡风墙、无列车通过桥梁时, 两线路接触网处横向风速基本相同, 而当列车通过桥梁迎风线和背风线时, 其接触网处横向风速急剧升高, 分别增加约28.9%和27.2%;安装一定高度挡风墙后, 随挡风墙高度的增加, 接触网处横向风速整体呈现减小趋势, 背风线风速减小较快; 无论单侧还是双侧挡风墙, 桥梁挡风墙合理高度均为2.8m。

Abstract: Based on 3D steady N-S equation and k-ε double-equation turbulent model, the influence of height of windbreak wall with holes on high-speed railway bridge on train aerodynamic performance was simulated by using finite volume method. The relationships among train overturning moment, wind speed at catenary position and the height were analyzed, and the accuracy of present numerical method was validated combining with wind tunnel test. Analysis result shows that after the installment of windbreak wall, the equivalent coefficient absolute values of lateral force and overturning moment decrease speedily with the increase of the height. At the same height, the equivalent coefficient of lift force of train located at leeward line is as half as that at windward line. As there are no windbreak wall or train on bridge, the lateral wind speeds at two lines'catenary position are almost equal, the speeds rise sharply by 28.9% and 27.2%respectively when the train passes windward line and leeward line. After the installment of windbreak wall, the lateral wind speed at catenary position tends to decline with the increase of the height, and the leeward line wind speed reduces rapidly. Whether it is single-side or doubleside windbreak wall, the reasonable height of windbreak wall with holes on high-speed railway bridge is 2.8m.
