| 摘 要： | 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6 m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...

| Abstract: | In order to define the risk associated with the cross wind along a railway line,the effect of the infrastructure scenario on the aerodynamic loads acting on a vehicle have to be investigated.In this work,the aerodynamic coefficients of the ETR 500 train,measured through wind tunnel tests,for the standard TSI infrastructure scenarios(flat ground with and without ballast and rail and 6 m-high embankment) and for a typical Italian viaduct are presented.Moreover,each infrastructure is characterized in terms of ... |
