360497 STUDY ON DETECTION OF SIGNS OF WHEELCLIMB DERAILMENT FOR RAILWAY VEHICLES(Safety,Technical Session)

Abstract

This paper presents study on the detection of signs of wheel climb derailment. The sensing method and detecting algorithm were examined. A 1/10-scale model of railway vehicle including one car body and two trucks as well as a special device that can simulate various climb-up derailments only for the chosen wheel are designed and made. Based on experimental derailment tests, sensing method and algorithm for detecting signs of derailment beforehand were proposed. It was found that the peak threshold of pitch angular rate and the integral threshold of roll angular rate of truck flame can be possible to detect of signs derailment.
