TURNOUT SYSTEM VIBRATION SIMULATION DURING TILTING TRAIN IN OPERATION

초록

Turnout is the device that functions to switch the train to other rail or cross with other trackbed and considerable portion of railroad accidents occurred is closely connected with the turnout, Thus the railroad authorities in many countries have concentrated their efforts on maintaining the turnouts safe, categorizing them into the vulnerable parts among the railroad facilities, and in an effort to reduce the accident, our railroad regulations also requires limiting the maximum speed at the turnout section. The turnout comprises the point, lead and crossing part. The turnout however is the only movable section among the peripheral device of the rail, which has a complicated structure and as rapid movement between the wheel and rail during operation is inevitable, the safety is always the major concern. This study thus was intended to measure, compare and evaluate the intensity of the vibration occurred at the crossing part when tilting train passes the turnout section and carry out the simulation to predict the intensity of impact vibration when tilting train accelerates.
