强风环境下列车运行安全保障体系的初步研究

STUDY ON THE SYSTEM TO ENSURE TRAIN OPERATION SAFETY UNDER STRONG WIND

  • 摘要: 我国地域广阔,风环境复杂,在这种自然条件下,既有线的列车提速和高速客运专线的建设发展,将使得列车在强风环境下的运行安全问题变得突出和严峻,建立强风环境下列车运行安全保障体系势在必行。该文从软件措施和硬件措施两方面入手,指出了安全保障体系的内容,在软件措施即运行管制方面,分析了获得管制风速的方法和铁路沿线风速的测试和预测流程,指出了必要的风洞试验和现场测试研究内容;在硬件方面,指出了防风栅的试验和设置流程以及车体外形优化、选线优化等方法。最终以框图形式指出了整个体系建立的流程和需要进行的分析和试验研究工作。

     

    Abstract: Our country has a vast territory, and wind circumstance is very complicated. With the development of High Speed Passenger Lines and speed up of trains, the security of train operation in strong wind is becoming serious and remarkable, and it is very important and necessary to establish an effective system to prevent wind induced accidents and ensure safety of train operation under strong winds. In this paper, it is indicate that the system consists of software measures and hardware measures. For software measures (operation regulation), the methods to get a regulation wind velocity were analyzed, the measurement and forecast procedures of the wind velocity along railway were indicated, the necessary wind tunnel experiments and field observation were analyzed. For hardware measures, experiments and setting procedures of a wind barrier were indicated; the optimum design procedure of a train aerodynamic shape and route selection of railway were pointed out. At last, the whole procedure to establish the system and necessary experiment work were shown by a flowchart.
