Abstract
Introduce a new type of non-adhesion braking mode - aerodynamic braking; Meanwhile we analyze the structure of the wind resistance brake mechanism. Based on commercial software Fluent, numeric simulation are applied to the flow field of high speed train with wind resistance brake mechanism in order to work out the pressure distribution law of wing plate and high speed train as well as wind resistance. Based on finite element theory, finite element model of wind resistance brake mechanism is built by ANSYS. Then we make static load analysis and modal analysis to the wind resistance brake mechanism. From the computation and analysis above we get some good conclusions.
