Abstract

In order to verify the performance of high-speed train and core equipments such as current collection system, sophisticated tests and evaluating procedures must be considered. In case of force sensor to test contact force of pantograph, it should customize the test instruments according to characteristics of pantograph. In this paper, the force sensor with a built-in strain-gauge which developed to improve measuring performance of contact force between the pantograph and catenary system is introduced. The test and evaluation results of force sensor's static and dynamic calibration with pantograph shows that its design is very suitable and applicable for on-line test. Henceforth, the force sensor will be applied to test interaction characteristics between the pantograph and catenary system on the high-speed line and expected by a part of measuring system for evaluating current collecting characteristics more reliably.

과거부터 고속전철 및 집전시스템과 같은 핵심 주요 시스템에 대한 성능을 검증하기 위한 정교한 시험방법과 평가절차는 국내외의 전문가들을 통해 연구되어져 왔다. 판토그라프의 접촉력 측정 하중센서는 판토그라프의 특성에 따라 특수제작이 필요하다. 본 논문에서는 판토그라프와 가선시스템 간의 상호작용 특성을 평가하기 위한 항목인 접촉력을 측정하는 방법을 개선하기 위하여 개발된 스트레인 게이지 내장형 하중센서를 소개하고자 한다. 판토그라프에 직접 설치하여 수행한 정적 및 동적 검증의 결과는 매우 신뢰성을 가지고 있어 향후 고속전철용 판토그라프의 보다 효율적인 집전특성을 평가하기 위한 측정시스템의 일부로 활용될 수 있을 것이다.
