| 摘 要： | 基于Wu建立的带航速三维水弹性理论,采用考虑自由液面效应的理想可压流体Green函数,提出了带航速和考虑自由液面的声介质中三维水弹性结构声辐射计算方法.对THAFTS三维水弹性计算程序进行修改,得到声介质中三维水弹性计算程序.针对无限大流体中的静态弹性球壳结构声辐射模型进行一系列数值计算,通过与解析结果的比较,验证了该计算方法和计算程序的正确性.进一步计算不同潜深、不同航速下弹性球壳的结构声辐射,以此为基础对该计算方法和计算程序进行进一步考核,同时分析了航速和自由液面对水下结构声辐射的影响. |

| Abstract: | Based on Wu theory on 3-D hydroelasticity of floating bodies with forward speed,the structuralacoustic radiation calculated method of 3-D hydroelasticity with free surface is proposed by utilizing Green function in ideal compressible fluid related to free surface.The existent 3-D hydroelasticity programme,THAFTS,is renewed.The validity of the calculated method and programme is checked by comparing with analytic results,based on a number of numerical calculation about structural-acoustic model of a static el... |
