摘要
应用统计能量分析建立了水下壳体的统计能量分析模型,结合算例研究了水下壳体的高频振动与声辐射特性,得出了一些有用的结论.事实表明该方法能有效地应用在水下壳体结构的振动与声辐射特性分析上,具有较强的工程适用性和可操作性.
The structure vibration m high frequency and sound radiation of shell is studied by means of statistical energy analysis (SEA). An SEA model of shell structure is established and an example is presented The results shows that the SEA model is suitable for the analysis of shell structure vibration and sound radiation and it can be used m engineering application.
