Research on protective performance of different shipboard structures subjected to air contact explosion with ANSYS / LS - DYNA

In this paper,the dynamic response of warship section with different shipboard protective structures subjected to air contact explosion was studied with ANSYS / LS-DYNA.According to the results,regularity between intersection angle of wing plates and protective performance of Y-shape and V-shape shipboard structures was discovered.The protective performance of Y-shape shipboard structures,better than that of V-shape shipboard structures,is steadily improving along with intersection angle increasing;while there is no regularity for V-shape shipboard,even though the protective performance is satisfying at some angle.Finally,Y-shape shipboard structure with 120 degree intersection angle of wing plate is given as the most efficient shipboard style.
