Description
Claims (1)
- 질량체, 스프링 및 댐퍼를 이용한 대형 구조물 동특성 시험용 가진기에 있어서, 불평형 가진모터에서 발생되는 가진력을 가진대상 구조물에 직접 작용시킬 때의 문제점을 극복하기 위하여, 스프링과 댐퍼로 이루어진 서스펜션과 질량체간의 고유진동수에 의한 공진현상(Resonance)을 이용하여, 불평형 모터에서 발생되는 구조물 가진력을 저주파수에서는 충분한 크고, 고주파수에서는 구조물의 파손 등의 안전성에 영향을 주지 않도록 안정된 가진력을 갖도록 불평형질량이 장착되고 서로 반대방향으로 회전하는 불평형모터와,상기 불평형모터에 의해 발생되는 가진력을 시험대상 대형구조물에 전달하는 매개체인 베이스 플레이트와,상기 가진기의 출력을 직접 측정하고 넓은 주파수대에 걸쳐 가진력을 쉽게 조절하도록 상기 베이스 플레이트에 장착된 힘 센서를 추가로 포함하는 것을 특징으로 하는 공진과 댐퍼를 이용한 대형구조물 동특성 시험용 가진기.
