电制动与空气摩擦制动防滑控制协同作用策略研究

Research on The Cooperative Control Strategy of The WSP between The ED Braking and The EP Braking

目前高速动车组及城际动车组在常用制动和紧急制动时多采用电制动与空气摩擦制动的复合制动形式,从动车组实际运用过程中擦轮事故入手,通过数据分析,研究和总结在线路低黏着条件下电制动防滑与空气制动防滑协同作用的机理,并建议和优化了电制动与摩擦空气制动防滑协同控制的策略。

At present,high-speed EMUs and intercity EMUs often use the combined braking mode of ED brake and EP brake in the case of service brake and emergency brake.This article starts with the rubbing wheel accidents during the actual operation of the EMU,and through data analysis,studies and summarizes the synergistic action mechanism of the WSP between the ED braking and the EP braking under the conditions of low adhesion,then proposes and optimizes the Cooperative Control Strategy of the WSP between the ED braking and EP braking.
