Numerical and experimental study of hydrodynamic impact and elastic response of one free-drop wedge with stiffened panels

摘要: Abstract This paper deals with the study of slamming load and response one complex 3D steel wedge deadrise angle 22°. The stiffened panels on both sides are made up 9 longitudinal stiffeners 5 transverse frames. In order to effect flexibility elastic responses, cross sections frames each side were designed different sizes. It is segment an idealized ship structure V-shaped bottom that was used in a series free-drop experiments impacting still water. acceleration, pressures, stress responses measured. this paper, uncoupled method combining Wagner theory finite element presented analyze problem for structure. matched asymptotic expanded predict motion pressure rigid body. Then pressures added model transient structural responses. numerical experimental results compared. Good agreement achieved hydroelastic effects discussed.
