Abstract:In this paper, the mixed mode function-modified MPS method was adopted to simulate the water-structure dynamic interaction during slamming impacts on the cross deck of trimaran. The water was considered as an incompressible inviscid fluid and the "conceptual particle" model was used to enhance the stability of the intense free surface interaction during the "filling-up" process under the cross deck. The numerical model for the coupled rigid and flexible modal superposition model was derived for the dynamics of the trimaran hull with rigid and flexible arches, and the flexible arch was simplified by a beam structure. The fluid and structure solvers were coupled in a standard iterative way. The results for rigid-body arch cases obtained with the use of improved free surface condition show good improvement, in comparison to the experiment data. From the study of flexible arch cases with different flexibilities, it is found that the relatively soft structure can reduce the local pressure and slamming load.
