摘要
针对南京地铁1号线既有车辆在例行检修中发现紧急制动距离存在超标现象,提出在增购车辆项目中引入清洁制动概念,即在高速时施加纯空气制动,达到清洁摩擦副效果,以保证列车紧急制动距离达标。介绍了清洁制动的基本控制逻辑,阐述清洁制动的开始、过程控制、结束等阶段的具体实施方案,经过1年多的应用表明紧急制动距离超标这一现象得到有效抑制。
Aim at the problem of vehicle emergency brake distance out of limits in the regular maintenance of Nanjing metro line 1 vehicles, a conditioning brake concept of applying just air brake to clean the brake shoes on the train with high speed was introduced in the added vehicle buying project, which ensured the emergency brake distance in the limits. The basic logic and realization of conditioning brake starting, continuing and ending was expounded. The application for over one year validated the proposed scheme.
