弹性结构振动和声辐射的相似性分析

Similitude Analysis of Vibration and Acoustic Radiation for Elastic Structures

本文以弹性平板为例，分析它在已知外力激励下，振动、耦合振动和声辐射的相似性，从而给出弹性结构振动和声辐射的相似条件和相似关系。

This paper investigates the similitude of vibration, coupled vibrations and acoustic radiationusing as an example rectangular plates excited by given forces, and presents the similitude conditionsand relationships of vibration and acoustic radiation for elastic structures.
