铁道车辆开始采用自动车门是为了减少车站和列车工作人员的人数。今天,除了这一优点之外,把旅客的安全、舒适和方便也作为风动门的设计目标,即通过取消杆件和罩之间的空隙提高安全性,通过减少噪音和气流改善舒适性,以及加大门孔宽度使旅客上下车更加方便。 Rail cars began to use automatic doors to reduce the number of station and train workers. Today, in addition to this advantage, the safety, comfort and convenience of travelers are also designed as the goal of a moving door to improve safety by eliminating the clearance between the lever and the cover, improving comfort by reducing noise and airflow, As well as increasing the width of the door so that passengers get on and off more convenient.
