摘要
开展复合材料夹芯板的损耗特性测试试验,获得了复合材料夹芯板结构内损耗因子,并以此作为数值计算的基础参数输入;采用声固耦合有限元分析法,对水下航行器上层建筑采用复合材料夹芯板后的振动声辐射特性进行分析;探索了壳板厚度参数对水下航行器上层建筑振动声辐射特性的影响规律,提出了复合材料上层建筑结构声学优化设计方案,旨在为上层建筑结构声学设计提供参考。
Test experiment of loss characteristics of composite sandwich panel is carried out. Loss factor of composite sandwich panel is obtained,and it is recognized the basic parameter input for numerical calculation.And use acoustical-structure coupling finite element analysis method,underwater vibration acoustic radiation characteristics of underwater vehicle superstructure with composite sandwich panel is analyzed. On this basis,influence rule of structure thickness parameters on vibration and acoustic radiation characteristics of underwater vehicle superstructure is studied,acoustics optimization design schemes of composite superstructure is proposed,which aims to provide a reference for acoustics design of superstructure.
