Development for pneumatic plug door system

공기식 플러그도어 시스템 개발

There are many EMU lines in korea. But only one type has been applied to passenger side door. This type is so called "Pocket sliding type". This type has some week points. To begin with, it is not good for decreasing the noisy form the outside of carbody. And the second time, if some obstacles are put between sliding door, only driver can operate re-open door switch manually ill driver's cab. This type is so dangerous for passengers. So many people want to the new door type that have no defect. KRRI joined forces with ANT corporation for pneumatic plug door system. This type will be good for decreasing the noisy, passenger′s safe. The project was started at the last year on November and will be finished on June, this year In this paper, we will deal with the role of cylinder, planetary gear, door control unit, dynamic mechanism, and the report of FEM, type test. This paper will contribute to tile electric motor control plug door system.
