Claims (3)
- 축부재의 진동 감쇠장치로서, 상기 축부재의 중앙부를 외감하고 외측부에 압전센서가 고정된 형상기억 스프링과, 상기 형상기억 스프링에 의해 외감된 축부재의 진동량에 따라 상기 압전센서의 전기적 신호를 입력하여 상기 진동량을 측정하는 진동량 측정부와, 상기 진동량 측정부의 출력에 따라 상기 형상기억 스프링의 양 단부에 통전되는 전압을 조절하는 전압제어부를 포함하며,상기 형상기억 스프링은, 공진 시 축부재의 변형이 큰 중앙부에 선형이나 스트립형 코일형태로 권취되고,상기 전압제어는 형상기억 스프링의 온도가 변화되어 일반적인 주파수(비 공진주파수)의 진동이 원통형 중공축에 가해질 경우 형상기억 스프링의 부착에 의한 강성 증가로 진동을 감쇠하고 특정주파수(공진주파수)가 원통형 중공축에 가해질 경우 부착된 형상기억 스프링에 전압을 가하여 생기는 저항열을 이용하는 형상기억효과에 따른 복원력을 이용하여 진동을 감쇠시키도록, 상기 축부재의 외주부에 가해지는 조임력을 비례적으로 조절되는 것을 특징으로 하는 진동 감쇠장치.
