高速铁路曲线外轨超高智能调节

Smart Conditioning in Superelevation of Outer Rail on Curve

当列车高速通过曲线时,由于离心力和向心力的作用,当列车通过曲线时,固定的外轨超高不仅对列车运行速度有很大的限制,也增加了轮轨磨损,威胁到行车安全。对列车通过曲线时车体受力进行了分析,结合铁路运输设备的特点,提出了铁路曲线外轨超高智能调节方法。

When the train speeds through the curve, due to centrifugal and centripetal forces, train wheelrail wear and tear of line outside is very serious. Fixed superelevations of outer rail not only have strict restrictions on train speed, but also increase wheel-rail wear and tear, and even cause threat to train safety. This paper makes an analysis of the forces on the train running through railway curve, and put forward a smart-conditioning method of outer rail superelevation on curve combining the characteristics of rail transportation equipment.
