基于响应面法的矢量水听器壳体优化设计付昌，葛松，陈伟皓，徐雨悦(上海船舶电子设备研究所，上海201108)摘要:随着海洋探测不断向深海迈进，大深度耐压矢量水听器成为未来发展的重要方向，矢量水听器的设计还应满足小尺寸、低密度的要求。针对耐压强度大与小尺寸、低密度之间相对矛盾的问题，本文在有限元软件中建立水听器耐压壳体三维模型，求解其内部应力分布，分析壳体的耐压失效形式，运用响应面法分析各设计变量对于目标参数的敏感度，对壳体结构尺寸进行优化，优化后的水听器密度从1.25g/cm3降低至1.03g/cm3，可以满足耐20MPa水压的工作要求，达到理想的设计效果。关键词：耐压强度；低密度；响应面法；优化设计中图分类号：TB565.1文献标识码：A文章编号：1672–7649(2023)12–0107–05doi：10.3404/j.issn.1672–7619.2023.12.020OptimaldesignofpressurevectorhydrophoneshellbasedonresponsesurfacemethodFUChang,GESong,CHENWei-hao,XUYu-yue(ShanghaiMarineElectronicEquipmentResearchInstitute,Shanghai201108,China)Abstract:Withthedevelopmentofoceanexplorationtothedeepsea,thelargedepthwaterpressureresistantvectorhydrophonehasbecomeanimportantdirectioninthefuture.Thedesignofvectorhydrophoneshouldalsomeettherequire-mentsofsmallsizeandlowdensity.Inviewoftherelativecontradictionbetweenlargewaterpressurestrengthandsmallsizeandlowdensity,thispaperestablishesathree-dimensionalmodelofthehydrophonepressurehullinthefiniteelementsoftware,solvesitsinternalstressdistribution,analyzesthepressurefailureformofthehull,analyzesthesensitivityofeachdesignvariabletothetargetparametersbyusingtheresponsesurfacemethod,andoptimizestheshellstructuresize.Afteroptimization,thehydrophonedensityisreducedfrom1.25g/cm3to1.03g/cm3,Itcanmeettheworkingrequirementsof20MPawaterpressureandachievetheidealdesigneffect.Keywords:hydraulicstrength；lightweight；responsesurfacemethod；optimaldesign0引言矢量水听器兼备声压通道和标量通道，能够空间共点地同步测量声场中的声压标量信号和振速矢量信号，具有低频性能好、灵敏度高、体积小、功耗低等特点[1]，在海洋环境监测和水下目标探测等领域有着广泛的应用，其耐水压性能一直是限制其在大深度水下应用的制约因素[2]。根据矢量水听器设计的基...
