Passenger Door System for Series E235 Train of East Japan Railway Company (Yamanote Line) Designed to Improve Transportation Quality

摘要

Electric door systems for rail cars are motor-powered devices for opening and closing passenger doors in accordance with the door operations of crew members. Fuji Electric has delivered rack-and-pinion type door systems to East Japan Railway Company for the Series E235 train (Yamanote Line), which started operation. The door system uses less permanent magnets than conventional products, thus reducing overall weight by 14%. Furthermore, by reducing the number of parts and adjustment points, the system reduces maintenance costs and failure rates. Moreover, by changing the type of locking device, the system achieves better obstruction pulling and anti-forced opening characteristics. Additionally, by improved control sequencing, the system is increased in sensitivity of obstruction detection and dragging detection.
