摘要

本文用瑞利公式研究了全无边折板矩形薄板的横向振动和声辐射。虽然瑞利-里兹法适用于各种边界条件组合，但在本研究中，该方法用于评估全无边板的模态特性。声压级由自由场的瑞利声学公式计算。本研究为那些有兴趣计算自由场中挡板板在特定点上的声压的人提供了一个快速的公式，而只需要用二维幂级数表示表面的振动。计算结果与有限元分析结果进行了比较。

On the acoustic radiation of all edges free rectangular thin plate

In this study, transverse vibrations and acoustic radiation of an all-edges-free baffled rectangular thin plate are examined by Rayleigh's formulation. While the Rayleigh-Ritz method is applicable for a wide variety of boundary condition combinations, in this study, the method is used for evaluating the modal characteristics of an all edges free plate. Acoustic pressure levels are calculated by Rayleigh's acoustic formula for a free field. This study provides a quick formula for those who are interested in calculating the sound pressure of a baffled plate on a specific point for a free field while only requiring the vibration of the surface to be expressed in terms of 2D power series. The results obtained from the formula are compared with the finite element analysis results.
