Whipping response analysis of slender stiffened cylindrical shell subjected to underwater explosion with bubble pulse

DONG Hai1,LIU Jian-hu2,WU You-sheng2(1 School of Naval Architecture,Ocean and Civil Engineering,Shanghai Jiao Tong University,Shanghai 20030,China;2 China Ship Scientific Research Center,Wuxi 214082,China)  
The underwater explosion induced whipping responses of the slender cylindrical shell of a submarine is one of the major factors of the structural damage,which may eventually result in loss of the ship's life.In order to investigate the influence of different relative configurations of the explosion on the whipping responses,the cylindrical shell is simplified as a beam with un-uniform cross sections in this paper,and the Double Asymptotic Approximation method(DAA) is employed to describe the coupling effect of the dynamic motions of the structure and the transient fluid field.The contributions of the first bubble pulse produced by the underwater explosion to the whipping responses of the structure are examined in terms of the dynamic bending moment of the beam.The variations of the bending moment with respect to the different dive depth,different distance and attack angle of the explosive relative to the submarine target are investigated.The results thus obtained may help to understand the underwater explosion induced dynamic behavior of a submarine,and to improve the shock-resistant design of the ship structure.
