궤간가변화차 차륜의 마모도 해석

초록

Gauge-changeable trains can be used to operate on the railways with different rail-gauges. The wheel-flange wear due to contacts of a wheel and different rails can affect the dynamical behaviour of vehicle, the maintenance period of wheels and the track structural damage. In this paper, the wear of wheels for a gauge-changeable freight wagon was analyzed numerically using ADAMS/Rail. The wear indices were calculated for a given wheel profile varying the rail condition, which showed that KNR wheel-profile is a little more preferable to Russian wheel-profile for reducing the wear of the wheels.
