Abstract

In this study, a test system which can test performance of curling pad was developed to support Korea curling team. The developed system consists of a water tank, a mechanical pad driving system that can perform sweeping movement using a curling pad on surface of ice made by the water tank, and temperature sensors monitoring ice and air temperatures. To control the temperature of ice and humidity/temperature of air around the ice, all system are installed in a chamber that can isolate the developed system from external environment. Eight kinds of curling pads were tested using the developed system. Test result showed that each curling pad revealed different rate of ice temperature increasing. The pad with the highest rate of ice temperature rising was found to be the same as the most preferred pad by the athletes. Therefore, it was confirmed that the method of measuring change of ice temperature by the sweeping performed in this study is an effective method to test the performance of the pad.

본 연구에서는 국가대표 컬링(curling) 선수들이 사용하는 컬링 패드(pad)의 성능을 평가 할 수 있는 시험 장비를 개발 하였다. 개발된 장비는 얼음을 생성 할 수 있는 수조, 수조에서 생성된 얼음 표면에 패드를 밀착시켜 스위핑(sweeping, 패드 왕복 운동)을 수행 할 수 있는 패드 구동 장치 및 얼음 속 온도를 측정 할 수 있는 측정 장치로 구성되었다. 수조와 구동 장치는 챔버(chamber) 형태의 구조물 내부에 설치하여, 챔버 내부 공기의 온도와 습도 조절이 가능하도록 제작 하였다. 개발된 시스템을 이용하여 8종의 컬링 패드에 대하여 스위핑 수행 시 얼음 속 온도 변화를 관찰한 결과, 컬링 패드에 따라 서로 다른 온도 변화가 관찰되었다. 실험을 통하여 관찰된 얼음 온도 상승이 빠른 패드와 선수들이 선호하는 패드가 일치하여, 연구에서 수행한 컬링 패드 스위핑에 의한 얼음 온도 변화를 측정하는 시험방법이 패드의 성능을 가늠하는 유효한 방법임을 확인 할 수 있었다.
