采用LS-DYNA数值模拟计算的方法，对高铁某站台列车进站时造成的空气扰动对雨棚的受力进行分析。主要分别模拟了两列车同时同向进站，两列车不同方向进站，单独一辆车进站4种不同情况下造成的空气扰动对雨棚的影响，给出其在不同时刻的等效应力云图，同时给出其不同情况下的最大应力值。

By adopting LS-DYNA numerical simulation calculation, this study analyzes the stress on canopy when the trains run into the station. Simulations are carried out in four situations, including the single train into the sta?tion, two trains into the station in the same direction and two trains into the station in different directions. It dis?cusses the equivalent stress contours at different time and also gives the maximum value of stress under different conditions.
