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

  • 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.
