당목을 이용한 종 구조의 모드 쌍 추출법

다국어 초록 (Multilingual Abstract)

Beating sound of an oriental bell means the periodic repetition of the strong and weak sound. Beat with a proper period makes the people feel as if the bell were alive and breathing. To control the beat characteristics, mode pair data of the bell structure are necessarily required. However, a huge oriental bell is usually struck by a swing of a heavy wooden hammer and therefore, only response signal such as acceleration or sound pressure can be measured. This study proposes a experimental method to extract the mode pair data from the power spectrum of the vibration response under the striking by a wooden hammer. Validity of the method is verified on a huge oriental bell.
