Analysis on causes of Faults in damaged Bell Crank of High Speed Line Turont

We carried out a vibration test to analyze causes of the damage in the plate of Bell Crank of the high speed Line turnout, at the section where the plate of high speed railway turnout get damaged from May 8th to 9th in 2006. In addition, through a test of the material quality, we performed an analysis of the qualities (of the components) composing the plate. The result indicates that the main cause of faults of the high speed line turnout, which is installed in the section of Chil-gok IEC, is the vibration. In this paper, effects on track-side equipments from vibration, and measurements to protect them from it are mainly analyzed and checked.
