东莞地铁2号线列车车门自动防夹故障分析及改进

Analysis and Measures on Anti-pinching Fault for Dongguan Rail Transit Line 2

东莞地铁2号线开通初期,列车客室车门频繁出现无障碍物情况下的自动防夹故障,严重影响了乘客服务质量。通过对门驱结构对比调查,分析了自动防夹故障原因,并从客室车门环境风压、结构设计及车门软件参数出发,针对性地提出了客室风压优化、机械尺寸调整、软件参数优化等改进策略。经实践验证,采取的措施合理有效,基本解决了自动防夹故障。

Anti-pinching fault with no obstacles occurred frequently to the door when Dongguan rail transit line 2 initially opened,which had a bad influence on the service quality of passengers.By comparing and investigating the structure of door drive,the causes of automatic anti-clamping fault were analyzed.Based on the environmental air pressure,structural design and software parameters of door,some improvement strategies were put forward,such as optimization of air pressure,adjustment of mechanical dimensions and configuration of software parameters.Practice proved that the measures adopted were reasonable and effective,and the anti-pinching fault was basically solved.
