摘要

借助流体动力学分析软件Star-CD，利用动网格技术，建立了不同车速下钝形和流线型列车通过隧道时的二维模型。分析了活塞风特性及其对接触网系统中接触线气动性能的影响情况。研究表明：在6 m高的接触线处，钝形列车形成的活塞风vy 的最大值约为流线型的2 倍，接触线受到向上的最大抬升力约为流线型的4 倍；在其他条件相同时，列车速度每增加10 m/s，接触线受到向上的最大抬升力增加约1 倍。

Abstract

By using software Star-CD and dynamic meshing technique, the two-dimensional models of blunt-shaped and streamlineshaped train passing through tunnel with different speed were built. The piston wind property and the influence of the piston wind on catenaries contact wires aerodynamic performance were analyzed. When the height of contact wires was 6 meter, the maximum value of the piston wind vertical components and the lift forces on contact wires formed by the blunt train were twice and quadruple of that formed by the streamline train. When the speed of train increased ten meters per second, the maximum lift force on contact wires would double.
