Finite Element Analysis of Wheel-set for Derailment Coefficient Measurement that have Plane Plate Shape

평면 플레이트 형상을 가진 탈선계수 측정용 윤축의 구조해석

Since a derailment of rolling stocks results in huge losses in properties and lives, the measurement of a derailment coefficient is a very important test item to estimate the running safety of rolling stocks. For a measurement of the derailment measurement of forces between the wheel and rail a measuring wheel-set should be made first. The process to make a measuring wheel-set has some stages for correct measurement. They are as follows; a finite element analysis of a wheel to find a position of holes at which vertical force shall be measured, a finite element analysis for the position of strain gauges.
