摘　　要：本文以水下1000 m复合材料耐压舱为研究对象,针对技术指标要求,对耐压舱进行复合材料夹层结构设计,通过有限元计算、铺层的多次迭代设计和结构校核,最终设计了带有内环筋,隔层面板和泡沫这种特殊“三明治”夹芯结构的碳纤维复合材料耐压舱,重量较铝合金结构减重40%。对制备的耐压舱试件进行15 MPa外压试验考核。试验结果表明,制备的复合材料耐压舱在使用条件下未发生渗水及结构破坏,能够在实现减重的同时满足使用要求,设计的复合材料夹层结构安全可靠,为未来水下耐压舱体的设计提供一定的参考依据。The underwater 1000 m composite ballast tank is taken as the research object in the paper.Based on the specified technical requirements,the composite sandwich structure of the ballast tank is designed.Through finite element calculation,multiple iterations of layering design and structural verification,the carbon fiber composite ballast tank with special sandwich structure incorporating inner ribs,partition plates,and foam was ultimately developed.This design reduces the weight by 40%compared to an aluminum alloy structure.The 15 MPa external pressure test was carried out on the prepared ballast tank specimen.The test results indicate that the prepared composite material ballast tank exhibits no water seepage and structural damage under the operating conditions,thereby meeting usage requirements while achieving significant weight reduction.The designed composite material sandwich structure is proven to be safe and reliable,which provides a certain reference for the future design of underwater ballast tank.
