摘　　要：黏着制动是目前轨道交通车辆最主要的制动方式,其制动力的大小取决于轮轨间的切线力,因而在制动过程中不可避免地伴有滑行的风险。随着车辆速度的提高,轮轨间的黏着系数降低,车轮滑行几率增大,文中通过对极端天气情况下高速动车组防滑失效问题的分析,研究了低黏着状态下防滑系统中防滑阀排风时间、电制动与空气制动防滑的协同作用方式、滑行判据及防滑策略的弊端,提出了在极端天气条件低黏着状态下避免防滑失效的应用措施。At present,high-speed EMU still use adhesive braking as the main braking method.Inevitably,there is a risk of sliding during the braking process.As the EMU speed increases,the adhesion coefficient between wheel sets and rails decreases,and the probability of wheel slide increases.Based on the analysis of slide incident of high-speed EMU under extreme weather conditions.This paper studies the cooperation mechanism of the WSP between the electro-dynamic(ED)brake and the electro-pneumatic(EP)brake under the low-adhesion condition.The judgments of slide and the WSP logic proposes solution to avoid slide incidence under low adhesion in extreme weather conditions.
