Aerodynamic Brake Study of Reducing Braking Distance and Decreasing Using The Energy of Braking of High-Speed Trains

With the rapid development of high-speed railway in China, the aerodynamic brake is very likely to be an important emergency braking mode of high-speed train in the future. This paper takes aerodynamic braking wing as the object, and uses the finite element software to divide the meshes, then analyses the model influenced by static stress. After simulating the vibratory frequency response of the model in the flow field, it finds that the largest deformation happens in the middle of the upper edge of the wind wing, when the wind speed gets to 500km/h and the load frequency to 4Hz. Some conclusions of this thesis can provide reference for researching the applying the aerodynamic brake in the high-speed trains and laying the foundation for solving the riding and braking safety problems.

Aerodynamic Brake

To solve the braking problems caused by train speed-raising, shorten braking distance and avoid probable wheel sliding arising therefrom, we launch a research into Aerodynamic Brake and design an aerodynamic brake mechanism, the wing plate of which can open and close bilaterally against the wind with opening angle controllable. Kinematic analysis and optimization design by using ADAMS are done in order to reduce the driving force and obtain more reasonable structural parameters. Research in this mechanism may provide important referential value for high-speed train braking technology.
