摘　　要：地铁列车制动系统是列车重要用风单元。过去多采用模拟式制动系统,利用中继阀控制制动缸的压力。随着数字式高速开关阀的控制技术的运用,地铁列车制动系统目前普遍使用了数字式制动系统取代模拟式制动系统,利用EP阀控制制动缸压力。此种对压力的控制方法与模拟式制动系统不同。传统的制动系统用风量计算方法仅考虑制动缸和管路耗气,本文提出一种新的用风量计算方法,通过搭建地铁列车制动系统AMESim模型对地铁列车制动系统各用风元件进行用风量计算,可获得制动系统工作中所有元件的总用风量。The braking system of the metro train is an important air unit.In the past,analogue braking systems were widely used,in which the pressure of the braking cylinder was controlled by using relay valves.Nowadays the digital braking system is widely used to replace the analogue braking system,and EP valves are used to control the pressure of the braking cylinder.This pressure control method is different from that of the analogue braking system,and the traditional air consumption calculation method for the braking system is no longer applicable.This paper proposes a new air consumption calculation method.By building an AMESim model of the metro train braking system,the air consumption of each air element is calculated,and the total air consumption of the braking system is obtained.
