超大潜深潜器结构重量控制措施分析

The analyse on the structure weight control technique of deeper submersibles pressure columnar hull

潜器下潜深度增加后,耐压壳体承受的海水压力也成比例增加。为了保证耐压壳体的强度和稳定性,在不更换壳体材料、不改变基本结构形式的情况下,壳体厚度将成比例增加,从而导致结构重量快速增长,结构重量与容积之间的矛盾更加突出。为了既保证耐压壳体的强度和稳定性,又确保潜器有效载荷不减少,必须采取有效措施控制结构重量。本文以典型带肋圆柱壳舱段结构为研究对象,以结构容重比参数为优化目标,采用解析法和有限元分析方法,在确保结构强度和稳定性的前题下,通过对超大潜深潜器结构重量进行优化计算,分析各项结构重量控制措施,从总体设计角度给出结构重量控制措施和建议,对超大潜深潜器设计和新材料研制具有一定的参考价值。

Increase with submersibles＇ submergence depth, the deep sea pressure on pressure hull will increase pro rata. For keep pressure hull＇s intensity and stability, without pressure hull material and basic structural format changing,the thickness of hull will increase prorata, so the structure weight will increase rapidly. The contradiction between pressure hull structure weigh and volume become more prominence. For keep both intensity and stability of the pressure hull structure and the effective load of submersibles nondecreasing,we must adopt effective technique to control structure weight. The paper aim at a type cylindrical hull structure with frame as research object,aim at the structure volume-weight ratio as optimize objective,we adopt parse method and FEM method analyse all structure weight control technique by deeper submersibles structure weight optimize calculate under the term of keeping structure both intensity and stability. We give out structure weight control technique and suggest from general design, the conclusion has reference effect to deeper submersibles design and new type material development.
