单/双壳体潜艇结构耐撞剩余强度特性研究

Comparison of Residual Strength Characteristics for Double and Single Hull Submarine Subjected to Impact Loading

  • 摘要: 单/双圆柱壳体结构是潜艇的两种典型结构形式。以单/双壳体潜艇典型结构为研究对象,分别设计初始深水静压强度相当的典型单/双耐压环肋圆柱壳体结构模型,基于MSC/Dytran罚函数接触算法,开展相同撞击强度载荷作用下结构模型耐撞动态响应特性分析,提取撞击后结构模型中耐压壳体结构的稳定变形位移场,作为MSC/Marc静强度求解的初始位移边界条件输入,通过有限元数值方法,对撞击后典型单/双结构耐压壳体结构的剩余强度特性进行比较分析。分析结果表明,当撞击载荷强度较低时,双壳模型的耐压壳体结构剩余强度较大,随着撞击载荷强度的不断增大,单/双壳结构耐压壳体结构的剩余强度将趋于一致,进一步提高撞击载荷强度,单壳体结构的剩余强度将高于双壳体结构。

     

    Abstract: The single and double hull are main types of submarine structure.In order to compare the residual strength characteristic of two type structures after impacted,the two type structure modes have been designed and used with same initial static strength.First,the dynamical response of this two structure modes under the same impact load was calculated based on FE codeMSC/Dytran,then the residual displacement field was picked out,the static strength analysis was carried out based on FE codeMSC/Marc.The comparison analysis results show that the double hull structure have higher residual strength,when the collision load is low.However,with the impact load increased,the residual strength of this two types structure will correspond with each other.
