Zusammenfassung: | The invention relates to the field of high-speed train aerodynamics and train wind resistance braking, in particular to a wind resistance braking effect evaluation method for a high-speed train with a wind resistance braking device. The method comprises the following steps: assembling different numbers of alternative wind resistance braking device prototypes by taking the streamline shape of a train body of a Chinese standard motor train unit and the configuration of a basic braking system as reference, establishing a Reynolds time-average train aerodynamic turbulence calculation model, and simulating and calculating the aerodynamic characteristics of a high-speed train assembled with the wind resistance braking device under different working conditions; on the basis of a train braking operation equation, a direct integral method resolving method suitable for the wind resistance braking problem is provided, a train is braked and stopped purely depending on a wind resistance braking device under a certain init |
