A Study for the Screen Door Motor System Driving Stiffness of Dynamic Load Condition

The initial urban railway was only required to perform its role as means of transportation. As the timeof staying in an underground platform was extended, it has been faced with the issues of environmental improvementas a living space. Therefore, the sliding automatic door, which is the basis of the screen door, is used widely forlarge distribution stores, hospitals, restaurants, and public offices for customers' convenience and as a convenient method to control access. Therefore, screen doors are required for the purpose of customers' convenience, securingsafety, establishing pleasant station buildings, and energy savings. It would be also necessary to develop the optimaldesign technology for a screen door system through the design of element parts and to ensure reliability. Therefore, this paper calculated, interpreted, and verified the theoretical weight of the composition parts to verify the design drivehardness of the motor for screen doors necessary for the safety of subways.
