In this paper, two wedges with deadrise angle 45 degrees made of steel and aluminum alloy respectively was designed and a series of free-drop model tests were carried out, we recorded time histories of water-entry velocity of models, slamming pressures on outer surface of stiffened panels and stress response of the structures. The time space distribution of slamming load and characteristic of structure dynamic response were studied. And through comparison analysis of slamming loads between two model’s corresponding measuring points, the effect of hydroelastic on slamming loads were discussed. Finally, an equivalent static analysis method to determine the structural response of hull structures under slamming loads was presented by analyzed the slamming loads and structure dynamic response that got from experiment combined with finite element method.
