특별세션 : 진동이론(3) ; 성덕재왕신종의 등가 종과 맥놀이 주기 조절

This study proposes an equivalent bell model for the Sacred Bell of the Great King Seongdeok. An equivalent bell model has the modal property of the real bell and it consists of an axi-symmetric bell body and a point mass. The bell model is constructed by the finite element analysis based upon the theory of a revolutionary shell. Using the equivalent bell model, the beat period can be controlled by decreasing the thickness of local area. This study aims at showing a beat period control method for a large bell baving the similar size to the Sacred Bell of the Great King Seongdeok.
