Abstract

This paper describes the evaluation of structural integrity and dynamic characteristic of inertial load test equipments for performance test of railway vehicle propulsion control system. The propulsion control system of railway vehicle has to be confirmed of safety and reliability prior to its application. Therefore, inertial load test equipments were designed through theoretical equation for performance test of propulsion control system. The structural analysis of inertial load test equipments was conducted using Ansys v11.0 and the dynamic characteristic was evaluated using Adams. The results showed that the structural integrity of inertial load test equipment was satisfied with a safety factor of 10.2 on the bearing part under combined load. Also, the structural stability of flywheel according to dynamic simulation was secured by the maximum oscillation displacement within 0.83mm.

본 논문은 철도차량용 추진제어장치의 성능평가를 위한 관성부하 시험설비의 구조안전성 및 동특성 평가를 연구하였다. 추진제어장치는 철도차량의 핵심 부품으로서 차량에 적용하기 전에 안정성 및 신뢰성 검증이 충분히 이루어 져야 한다. 따라서 추진제어장치의 성능시험을 위한 관성부하 시험설비를 이론식을 바탕으로 하여 설계하였다. 설계된 관성부하 시험설비에 대해 Ansys v11.0을 이용하여 구조해석을 수행하였으며, ADAMS를 통해 동특성을 평가하였다. 관성부하 시험설비의 구조안전성은 조합하중하의 베어링에서 안전계수가 10.2로 만족하였다. 또한, 동적 시뮬레이션에 따른 플라이휠은 0.83mm이내의 최대진폭변위로 구조적 안정성이 확보되었다.
