Development of numerical simulation technique to predict pressure and structural response due to water impact

摘要

A numerical simulation technique to predict structural response due to water impact caused by slamming or green water on deck is proposed. This technique is based on the assumption that the effect of fluid-interaction is small, pressure and structural response are able to calculate separately. MPS method, a particle method, is employed to calculate pressure. Dynamic response of structure is calculated using this pressure by usual finite element analysis method. Applicability of such technique is demonstrated by the simulation of the drop test of cylinder and wedge model on the water.
