HEMU 430X 열차 지상증속 시험시 궤도구조 거동분석

초록

The HEMU-430X (High Speed Electric Multiple Unit, 5M 1T), which project was launched in 2007, was developed by Next Generation High-Speed Rail Development R&D Project. The newlydeveloped prototype was in pilot run on Kyung-Bu 2nd phase High Speed Line and HEMU-430X recorded a speed of 421.4km/h in a test run on March 28th, 2013. For test run on operation line, structural safety was evaluated and field test of railway structure was conducted by “test run manual”. Tests of track structure were carried out from July 2012 to March 2013 according to the speed increase of HEMU. In this paper, the behavior of track is evaluated after test results are analyzed by test item.
