摘　　要：[目的]以无人潜器耐压结构轻量化设计技术为背景,以圆柱壳段为对象,开展典型材质耐压柱壳段承载特征规律研究。[方法]首先,根据耐压壳力学特性,分析得出5种典型材质耐压壳段的承载规律和最优临界承载设计值(同时发生应力强度失效和稳定性失效);然后,基于工程需求,进一步探讨不同潜深时各典型材质耐压壳段的承载特性。[结果]结果显示,随着潜深的增加,壳板的失效模式将由稳定性破坏逐渐转变为强度破坏,最优临界承载设计值与材料属性有关;考虑承载效率等因素,在进行圆柱形耐压壳体材料选型时,300 m潜深范围内应选用铝合金壳体,300~600 m潜深范围内宜选用钛合金和玻璃纤维复合材料壳体,600~1000 m潜深范围内建议选用钛合金和碳纤维复合材料壳体,1000~3000 m潜深范围内的最佳方案则选用碳纤维和硼纤维复合材料壳体。[结论]所做研究可为不同材质无人潜器耐压壳体材料选型提供依据。[Objectives]This study takes a typical pressure hull segment of an unmanned underwater vehicle(UUV)as the object and explores its load bearing capacity law based on lightweight design technology.[Methods]First,several typical materials are analyzed using the mechanical properties of the pressure hull,load law and optimal critical load design value(stress strength failure and stability failure occur concurrently).The bearing properties of a typical pressure hull with varying depths are then discussed further in terms of the specific engineering requirements.[Results]The failure mode of the shell gradually transitions from stability failure to strength failure as the depth increases,and the optimal critical load design value is proportional to the qualities of the material.Taking bearing efficiency and other factors into consideration,aluminum alloy shells should be selected within the 300 m depth range,titanium alloy and glass fiber composite shells within the 300−600 m depth range,and titanium alloy and carbon fiber composite shells within the 600−1000 m depth range.In the 1000−3000 m depth range,a carbon fiber and boron fiber composite shell is the ideal solution.[Conclusions]The findings of this study can be used to guide the design of pressure hulls for UUVs made of various materials.
