Latest Trend and Safety and Reliability Technology of Rolling Stock Doors

摘要

Fuji Electric has developed and commercialized a door operating equipment (linear motor system and FCPM system) with a simplified mechanism by applying the motion direction of a motor to the linear motion of the side sliding door. The door operating equipment for the side sliding door of rolling stock is an important component that ensures the safety of passengers when they are boarding, alighting and traveling, and it may affect trains' punctuality. Consequently, the system is required to be safe, reliable, high functional, and maintenance saving. These characteristics have been achieved in a safety evaluation that was conducted at the design stage and that included failure mode effect analysis and hazard analysis, and they have also been ensured with control technologies such as triple feedback, external force suppression and push-back control.
