碩士 === 國立中央大學 === 機械工程研究所 === 92 === Abstract
This paper is discusses the vibration and corresponding sound field of the holed plate excited by a point sound source. The plate is perforated into four holes in the center of symmetry. The vibration analysis is based on the technique of the “Ectoplasm”. The equation of motion of the plate is derived by the Hamilton’s principle. The dynamic response of the plate excited by a point sound source is solved.
In order to deal with the acoustic field of the holed plate, the Kirchhoff-Helmholtz integral and the Green’s function are used. The sound pressure distribution of the plate is investigated with different positions of the holes.
