Abstract

A cutting head is an attachment on the front of an excavator that cuts or grinds rocks. Cutting tools, called pick cutters, are arranged on the surface of the cutting head. The exact arrangement and configuration of pick cutters is one of the most important factors in determining grinding efficiency. This study focuses on the problem of automation for pick arrangement design, in order to make the design process more efficient and convenient. Design automation was carried out using RecurDyn/ProcessNet, and it was composed of three parts: 'Drum set', 'Pick load', and 'Pick arrangement' sections. The presented method helps to decrease costs attributed to designing cutting heads and can be used to generate a wide range of attachment mechanisms.

커팅헤드 어태치먼트는 굴삭기에 부착되어 사용되며 절삭 도구인 픽커터가 커팅헤드에 배열되어 암석이나 낙후된 건물을 파쇄 또는 절삭하는 작업에 사용된다. 암석을 절삭할 때 픽 커터의 배열은 절삭 성능과 연관성이 있는 요소이다. 본 연구는 픽 배열 설계 자동화를 수행하여 설계 소요 시간 및 검증 시간을 단축시켰으며, 배열에 따른 시스템의 거동을 예측하는데 활용하였다. 픽 배열 설계 자동화 방법은 RecurDyn/ProcessNet을 통해 수행하였으며, 설계 자동화 프로그램은 Drum set, Pick load 그리고 Pick arrangement의 세 부분으로 나누어 진행하였다. 이를 통해 커팅헤드 어태치먼트의 설계 비용 절감과 다양한 메커니즘 별 전용 어태치먼트의 설계에 활용할 수 있다.
