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

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.
