in this paper, a numerical computation of pressure on overline bridge surface by a high- speed train head is carried out with 3d panel method.
采用三维不可压缩势流模型和面元法,对高速列车通过时作用在跨线天桥表面上的气动压力进行了数值计算。
results of the computations show that on overline bridge a pressure pulse occurs while a train passes. the coefficients of the pressure pulse range from-0.135 to 0.095.
