Review of Wheel and Lateral Force at Rail for Train running performance

열차 주행평가를 위한 윤중, 횡압 측정 방법의 검토

It is of utmost important that track loads at rail induced by running train was usually obtained for track performance evaluation. A reaction force of track was measured wheel loads and lateral force by strain gauges on the rail, and then it was obtained to derailment coefficient and variational ratio of wheel load from its relationship. In this study, a existing monitoring system methods with many manpower working were reviewed about measurements, process of testing, and how to obtain accurately measured data.
