EVALUATION OF NOISE EMITTED FROM THE CROSSING OF THE IMPROVED TURNOUT SYSTEM

초록

In Korea, it is planned to adopt the high speed tilting train, which operates at the maximum speed of 180 km/h, at conventional lines by the year of 2010. However, for the application of the tilting train to conventional lines, it is prerequisite to establish a stable turnout system allowing the tilting train to pass through it without reducing speed. Therefore, the improved turnout system for the speed-up of conventional lines has been developed and the prototype of the turnout system has been constructed. However, characteristics of vibration and noise caused by trains at the crossing which is most critical part of the turnout system have not been clarified. In this study, evaluation of noise generated by trains at the crossing was performed through the field measurements. Field measurements of noise at that of the conventional and high-speed turnout system were also carried out for comparison.
