摘要
利用SYSNOISE软件采用有限元+边界元方法计算了一四边简支的平板在空气中和水中的振动和声辐射,并将计算的结果与有关解析解进行分析比较.结果表明2种方法结果相近,这就相互验证了对于计算简单结构2种方法的合理性与准确性.
Numerical method on vibration and sound radiation of a simply supported plate in different medium by SYSNOISE software is systematically analyzed in this paper. The paper compares the result of numerical method with the theory result in the article ＂Sound radiation by a simply supported unbaffled plate＂ by B. Laulagnet. It shows that there is not too much difference between the two methods. In the mean time it proves that the accuracy and rationality of these two methods.
