Development of Electric Plug Door and Test Results

초록

The noise coming from outer side of EMU has been an important issue for the passenger comfort because high speed operation has been required. The main cause of increased noise is the imperfect air tightness of passenger doors. The plug-in door system has advantages for the noise reduction in the high speed area. Recently, many types of plug-in door along to driving type are introduced to reduce noise and enhance reliability. Electric plug-in door has been developed to correspond to performance in actual operation circumstances. In this paper, I will deal with the role of several units of plug-in door, development process and the test results.
