Experimental investigations on small-and full-scale ship models with polyurea coatings subjected to underwater explosion
文献摘要：
Nowadays,the mitigation of damage to a ship caused by the underwater explosion attracts more and more attention from the modern ship designers.In this study,two kinds of scale tests were conducted to investigate the effects of polyurea coatings on the blast resistance of hulls subjected to underwater explosion.Firstly,small-scale model tests with different polyurea coatings were carried out.Results indicate that polyurea has a better blast resistance performance when coated on the front face,which can effectively reduce the maximum deflection of the steel plate by more than 20％and reduce the defor-mation energy by 35.7％—45.4％.Next,a full-scale ship(approximately 50 m x 9 m)under loadings produced by the detonation of 33 kg of spherical TNT charges was tested,where a part of the ship was coated with polyurea on the front face(8 mm+24 mm)and not on the contrast area.Damage char-acteristics on the bottom were statistically analyzed based on a 3D scanning technology,indicating that polyurea contributes to enhancing the blast protection of the ship.However,damage results of this test were different from those of the small-scale tests.Moreover,the deformation area of the bottom with polyurea was greatly increased by 40.1％to disperse explosion energy,a conclusion that cannot be drown from the small-scale tests.
