충격하중의 측정의 단점은 무엇인가? | , force sensor, strain gauge)이 존재한다. 충격하중의 측정은 측정 장비의 동적 특성이 고려되어야하기 때문에 정하중 측정법에 비해 센서 설치 및 데이터 획득이 어렵다(Sundin and Jonsson, 1985). 충격하중이 발생되는 구조물에 대해 로드셀 및 스트레인 게이지를 이용한 다양한 연구가 보고된 바 있다(Baker and Dove, 1962, Suzuki, 1971, Zhang et al. | |
암반 천공 기계장치는 무엇인가? | g., hydraulic breaker, crusher, top-hammer, TBM)는 타격력을 전달받아 암석과 암반을 파쇄하거나 천공하는 건설기계이다. 이 장비들은 암반 시공, 터널굴착, 자원 및 골재 생산, 건축물 해체 등 다양한 건설 산업분야에 활용되고 있다. | |
진동기반 하중추정 기법은 어떻게 구분되는가? | 진동기반 하중추정 기법은 가진원으로 부터 발생하는 소음 및 진동 에너지의 흐름으로 주요전달경로를 파악과 하중추정에 유용 하며 기계시스템을 구성하는 각 부품의 민감도 파악이 가능한 방법이다(Kim and Lee, 2008). 이 기법은 구조기인(structure borne noise)과 공기기인(air borne noise)으로 구분된다(SIMENS, 2014b). 구조기인 소음은 발생되는 진동이 구조물을 통해 전달되며, 공기기인 소음은 공기를 매개로 전달된다. |
