Similarity research of anomalous dynamic response of ship girder subjected to near field underwater explosion

CuO0A(N"p+jO0 水利论文^~-iw:r

Abstract:The final anomalous sag distortion of the ship girder subjected to the near field underwater explosion (undex) below the middle ship is studied.The sinking exercise of Spruance class destroyer DD973 sunk by one MK48 torpedo is first presented,and a simulation model is established.The exponential attenuation phase,the reciprocal attenuation phase,the post reciprocal attenuation phase,and the negative pressure phase of the undex load are precisely applied in this model.The fluid-solid interaction,the added water mass,the gravity,and the change of buoyancy are also taken into account.The similarity theory is then used to analyze the dynamic response of the ship girder.Similarity parameters and theory prediction formulae of the dynamic response of the ship girder are presented.The physical meaning and influences of these similarity parameters are analyzed.
