摘　　要：无论是直通式还是间接式,世界各国高速列车制动系统多采用电空制动来实现。在分析研究国内外高速列车减速度设计的基础上,结合我国高速列车运营模式及电空复合的实际情况,以充分利用黏着、尽量减少制动距离为目标,设计了CRH380B高速列车制动系统紧急制动减速度曲线。根据该曲线,通过系统仿真的方法,确定了制动缸压力。Electro-pneumatic （EP） brake system is applied in almost all the high speed trains in the world, including direct and indirect EP brake system. This paper describes the design method of deceleration of high speed train based on analysis of main high speed trains in the world according to the principle that the adhesion is utilized as much as possible and brake distance as less as possible. And then, deceleration curve of CRH380 is defined. Brake cylinder pressure is calculated accordingly.
