摘　　要：列车制动装置能实现列车的减速运行或停止,从而保证行车的安全。在任何情况下(包括在故障条件下)、在一定的距离内,列车绝对安全地停下来,这称之为安全制动。空气成为列车制动介质可以追溯到百年以前。空气制动从利用列车制动管传递制动指令,发展到在动车组上用微机控制实现阶段制动、阶段缓解,使空气制动的调速精度越来越高,防滑行、状态诊断等智能化的程度也越来越高。长期以来,空气制动已成为列车安全制动的代名词。Train braking devices can enable train deceleration and stopping operations,thus ensuring operational safety.That a train shall come to a complete and safe stop within specified distance under any conditions(including faults),is termed as safe braking.Using air as train braking medium dates back over a century.Air braking has evolved from using train brake pipes for braking commands transmission to using microcomputers in EMU(electric multiple units)for phased braking and phased release,which gradually increases the precision of air braking speed regulation and the intelligentization level of aspects such as anti-skid and status diagnosis.Over the long term,air braking has become synonymous with train safe braking.
