Abstract

Drifter is equipment which is hard to localize. Performance of prototype hasn't performed well compared to product of leading companies even though advanced foreign firm's product were dead copied. This study shows cases of approaching the factor which produces performance gap through drifter hydraulic analysis model which is core component of rock drill. Progression of procedure is following. 1) Securing reliability of the analysis model by comparing impact test result with analysis result. 2) Drawing a graph which indicates performance gap between prototype and drifter of advanced foreign firm by using analysis model. 3) Approaching the factor which produces performance gap with analysing variable of the analysis model. Software used for this analysis is SimulationX.

드리프터는 국산화개발에 어려움을 겪고 있는 장비이며, 외국선진사의 제품을 데드카피 하여도 시제품의 성능이 뒤떨어지는 현상이 발생하여 왔다. 본 논문은 천공기의 핵심부품인 드리프터의 해석모델을 활용하여 성능격차를 유발하는 요소를 분석하는 사례를 보여준다. 진행절차는 다음과 같다. 우선, 타격시험을 수행하여 해석모델의 신뢰성을 확보한다. 그리고 해석모델을 활용하여 외국선진사 제품과 시제품의 성능비교그래프를 도출한다. 마지막으로 해석모델의 변수를 분석하여 성능격차를 유발하는 인자에 접근한다. 사용된 소프트웨어는 독일 ITI사에서 개발된 SimulationX이다.
