초록

탄성회전축을 위한 실제적이고 효과적인 댐퍼를 개발하기 위하여 4개의 새로운 스퀴즈 필름 댐퍼들이 실험적으로 연구되었다. 이들 중에서 원통형 부쉬 댐퍼가 가장 효과적인 것으로 선택되었고 볼베어링으로 지지된 실험 회전축에 적용되었다. 이러한 회전축은 위험속도를 지나서 안정된 운전이 관찰되었다.

Four new types of squeeze film dampers have been experimentally investigated to develop a practical and effective damper for flexible rotors. The cylindrical bush damper was selected as the best one among them and applied in a test rotor supported on ball bearings. A stable running of the rotor exceeding the critical speed was observed.
