Abstract高速铁路挡风风障在减小列车在大风环境中运行的气动荷载的同时,自身具备良好的抗风能力和结构稳定性亦十分重要。为此,提出和设计出一种新型的由双层带孔薄板构成的透风式腔室耗能型挡风风障,并采用数值模拟方法对无挡风风障单层结构和腔室结构挡风风障的挡风作用及自身抗风性能进行计算和分析。结果表明,单层、腔室型挡风风障均可明显减少横风作用于列车的气动荷载,但它们的流场结构存在较明显的差异,且腔室结构风障所受的气动力较小;与单层风障相比,腔室型风障对列车气动荷载具有更好的减载效果以及更强的自身抗风能力和结构稳定性。通过改变腔室结构的两层薄板上透风孔的孔径比,可调节两层薄板的受力分配。腔室耗能型挡风风障的提出,为挡风风障的研究提供新的思路和方法,也可为高速列车的防风设计提供参考与依据。
