Characteristics of Track Irregularity Measuring System of HSR-350x

초록

HSR-350x which was developed by R&D project for Korean Hi-Speed Railway of Ministry of Construction & Transportation, is trial running on Kyung-bu high-speed line, and achieved 350km/h on increasing speed test in 2004, the forth attainment in the world. HSR-350x has over 400 sensing channels and it has monitored and saved the data during the test run. The authors suggest the installation of the high speed track irregularity measurement system to HSR350x and combination the measurement system. The track irregularity measurement system has 0.25m sampling distance and can work at 350km/h theoretically. HSR-350x was constructed in 2002 at the maximum speed of 350km/h. And it is composed of 7cars
