Research progress in railway safety under strong wind condition in China

The ongoing research work and the further research plan on railway safety under strong wind condition in China were both described.The main contents are as follows: research method of railway safety under strong wind condition,including numerical calculation,wind tunnel test,online real vehicle experiments,theoretical analysis,etc;research on aerodynamic laws of trains under strong wind condition,such as aerodynamic drags of trains,air lift characteristics of trains,air lateral characteristics of trains,crossing pressure waves of trains,aerodynamic characteristics of trains under wind-vehicle-railway-local area coupled condition;research on critical running speeds of trains under strong wind condition,such as wind characteristics,wind aerodynamics,safe running speeds of trains under special conditions caused by mechanical power;research on measures of railway safety under strong wind condition,including making the plan of running speed limitations and stops of trains under the different combinations of wind speed-railway condition-train shape-train load condition,designing the optimizing shapes of trains,setting the break wall,and establishing the strong wind monitoring and warning system,etc.
