空气动力制动制动风翼纵向位置制动力规律
Rule of Aerodynamics Braking Force in Longitudinal Different Position of High-speed Train
摘要
Abstract
Characteristics of the flow field around the brake panels are analyzed when all carriages of the train are equipped with aerodynamic brake.The kinetic rule is acquired that the first windward brake panel produces the largest drag, and the drag is reduced step by step in the windward.Then, principle of the braking force is also studied by taking a high-speed train model as an example, when the vehicles with the pantographs are not equipped with brake panels in order to reduce the impact of brake panels on the pantograph.This principle of braking force is compared with the rule of braking force when all carriages are equipped with brake panels.Finally, an analysis is made of the braking force effect generated by aerodynamic brake.关键词
