横风对高速列车逆向过岔安全性的研究
Research on the Safety of Crosswind on the Reverse Crossing of High-Speed Train
摘要
Abstract
In order to obtain the safety performance index that is most suitable for the performance evaluation of high-speed trains passing through turnouts under crosswind,the operation safety domains of high-speed trains passing through turnouts in straight and side reverse directions under crosswind are proposed.By establishing the aerodynamic model of high-speed trains passing through turnouts and the dynamic model of crosswind-train-turnout coupling multi-body system,the safety of high-speed trains passing through turnouts under crosswind was deeply explored.The results show that under the action of crosswind,the pressure on the windward side in-creases significantly,and the obvious pressure difference is formed on both sides of the head car,which makes the head car more prone to derailment and rollover during operation.When the high-speed train passes through the turnout directly and reversely,when the crosswind wind speed is not more than 15 m/s,the high-speed train can pass through the turnout at a speed of 250 km/h;when the crosswind speed reaches 20 m/s and above,the speed of the high-speed train should be less than 250 km/h.When the crosswind speed is greater than 15 m/s,the speed of the high-speed train side should be less than 80 km/h.Under the action of crosswind,the head car is more prone to derailment and rollover when the high-speed train runs.When the high-speed train passes through the turnout directly and reversely,when the crosswind speed reaches 8 and above,the speed of the train passing through the turnout should be less than 250 km/h.When the side of the high-speed train passes through the turn-out reversely,when the crosswind speed reaches 7 and above,the speed of the train passing through the turnout should be less than 80 km/h.The research results can provide reference for the smoothness and safety of high-speed trains passing through turnouts under different crosswind conditions.关键词
