The Characteristic of Radiation Efficiency from Harmonic-excited Cylindrical Radiator
조화 가진에 의한 원통형 음향 방사기의 방사 효율 특성
Abstract
Radiation efficiency of a cylindrical shell whose surface vibrates under harmonic distribution is investigated by theoretical solutions and Boundary Element Method. The vibration modes of a cylindrical shell is determined from experiment and is compared with the result of Finite Element Method. Harmonic vibration response of the cylindrical shell under the point excitation and the radiation phenomena from its response is analyzed by Finite Element Method and Boundary Element Method.
