摘要

本文分析了集中质量对振动薄圆板声功率和共振频率的影响。包括流固耦合和声波辐射效应。采用本征函数展开来表示板的横向位移。近似地确定适当的模数以获得物理上正确的结果。在此基础上，得到了精度较高的数值结果。辐射声功率被用来确定共振频率。通过对激振器运动部件的附加质量进行建模，证明了引入集中质量的合理性。

The effect of a concentrated mass on the acoustic power and the resonant frequencies of a circular plate

This study presents an analysis of the eﬀect of the concentrated mass on the acoustic power and the resonant frequencies of a vibrating thin circular plate. The ﬂuid-structure interactions and the acoustic wave radiation eﬀect have been included. The eigenfunction expansion has been used to express the transverse displacement of the plate. The appropriate number of modes is determined approximately to achieve physically correct results. Then highly accurate results are obtained numerically. The radiated acoustic power has been used to determine the resonant frequencies. The introducing of the concentrated mass is justiﬁed by modelling the added mass of the moving component of the exciter.
