Abstract

The wearing slider of the rail motor car's pantograph is considerable changed by the type and the material properties. Especially, precipitation and arc influences are main factors decided to life time of wearing slider and contact wire. This study is wearing phenomenon analysis of Cu-type wearing slider with high electric conductivity and resistance arc through experiment by running train. Author observed that wearing phenomenon of Cu-type wearing slider with normal and abnormal wearing characteristics and comparatively analysis precipitation, mileage and weight influences of exchanged Cutype and Fe-type wearing sliders. In this paper result showed that necessity for the application which is the Fe-type of wearing slider had superior wear resisting capacity etc., through tribology approach.

전동차의 집전장치용 주습판은 형태와 재질에 따라 마모현상에 상당한 차이가 있으며 특히, 강수량에 따른 이상마모, 아크에의한 급격한 이상마모는 전차선과 주습판의 수명을 결정하는 주요인자로 작용한다. 본 연구는 현차 실험을 통하여 우수한 전기전도도 및 내아크성을 가진 동계주습판의 마모현상을 정상마모 특성이 관찰된 동계주습판과 우천 시 국부적으로 이상마모 특성이 관찰된 동계주습판에 대하여 강수량, 주행거리 및 주습판의 교환 후 중량을 상호 비교하여 분석하였다. 트라이볼로지적 접근을 통하여 내마모성 등이 우수한 철계습판체의 적용 필요성을 본 실험적 연구를 통하여 제안하였다.
