摘要：In this paper, a series of water impact simulations is carried out by using fluid-structure interaction (FSI) function of the nonlinear dynamic structural analysis code LS-DYNA. Water impact phenomena of wedge shaped body and circular cylinder body are simulated in the present study. For the purpose of the validation of numerical simulations, the water impact pressure's peak values, pressure distributions and structural responses are compared with conventional theories and experimental results.A series of rigid wedges' water impact simulations is performed and water pressure values are compared with conventional Wagner's theory and experimental values. Then, a series of elastic cylinders' water impact simulations is performed and structural responses are compared with experimental values. It is found from the present study that water pressures and structural responses calculated by FSI analyses using some models are in good agreement with Wagner's theory and experimental results.
