为了明确铁路轨道沿线横风所造成的危险,就必须探讨基础设施对列车气动载荷的影响。本文介绍了在标准的TSI基础设施(有碴轨道和无碴轨道以及6m高路堤)和标准的意大利高架桥路面上,通过风洞试验所测试的ETR 500列车的气动力系数。每一种基础设施的特性都分为有列车和无列车2种状况进行研究。通过对比不同情况下的试验结果,指出了基础设施对气动载荷的影响。
In order to clarify the danger caused by the crosswind along the railway track, it is necessary to explore the impact of infrastructure on the aerodynamic load of the train. This article presents the aerodynamic coefficients of an ETR 500 train tested by a wind tunnel test on a standard TSI infrastructure (ballasted track and ballastless track, 6m high embankment) and a standard Italian viaduct. The characteristics of each of these infrastructures are divided into a train and a train-free condition. By comparing the test results under different conditions, the impact of infrastructure on aerodynamic loads is pointed out.
