摘　　要：针对广州地铁4号线直线电机车辆出现轮轨粘着系数降低时紧急制动距离延长问题,提出了对既有运营车辆增加撒砂装置和紧急制动优先使用电制动的改造方案,详细介绍了2种方案在既有运营车辆上实施改造的基本原理和特点。According to the question of wheel-rail adhesion coefficient reducing the extension of the emergency braking distance of the vehicle of Guangzhou metro line 4 with linear motor, this paper proposed modified schemes by sanding operations and emergency braking device priority to use electrical braking. The basic principles and characteristics of two schemes were introduced in detail.
