Railway Vehicle Derailment Simulation for Derailment Detection System in Early Signs

摘要

This paper proposes a derailment detection system in early signs of a railway vehicle. The proposed system detects abnormal vehicle signs before derailment using micro-electromechanical system acceleration sensors for automobiles. The new derailment detection algorithm was proposed in the former report. In this paper, a real-scale vehicle simulation is performed to apply the new derailment detection algorithm to an actual vehicle. At first, 1/10-scale vehicle simulation results are verified by using experimental results to indicate a reliability of the real-scale vehicle simulation. Finally, the real-scale vehicle results are performed in some derailment conditions.
