摘　　要：动车组开关门的稳定可靠性是保障动车组安全运行的重要指标,文章通过对CRH2A动车组车门动作原理进行分析,总结得出动车组总风压低、调整螺钉过紧以及驱动机构的抗磨卡滞是导致车门关闭故障的主要原因,并针对上述故障原因提出了针对性防控措施,进一步降低了车门故障率。同时通过试验和数据分析发现车门关闭时间、关门图标以及车门关闭的信号采集不合理,存在一定的安全隐患,对此提出了逻辑优化方案,进一步保障了动车组的安全运行。The stability and reliability of car door opening and closing is an important index of the safe operation of the EMU.This article analyzes the action principle of the car doors of CRH2A EMU,summarizes the main causes of car door closing fault including the low total air pressure,the excessive tightness of the adjusting screw and the stuck anti-wear element of the driving mechanism and proposes targeted preventive and control measures according to the above-mentioned causes of fault to reduce the fault rate of car doors.In addition,it turns out from the test and the data analysis that the signal acquisition related to closing time,closing icon and closed status of car door is not reasonable and hides some safety hazards,therefore the article proposes a logic optimization solution to further guarantee the safe operation of the EMU.
