摘要

Parameters setting in numerical simulation of Fluid-Structure Interaction (FSI) is important to get accurate results. A variable without units was defined to describe the mesh density. Effects of that variable and coupling control parameter in numerical simulation of FSI were studied. As an example, the underwater contact explosion on circular plate was simulated using the FEM programe LS-DYNA. The results of numerical simulation were compared with experimental data. The results showed that calculation errors were reduced at first and then increased according to the mesh density increased. Optimum range of mesh density was 2-3 and ratio of fluid mesh density to structure mesh density was 2-1. The optimum aspect ratio of structure mesh does not exceed 2. Penetration could be modified through adjusted coupling control parameters. The modifying way had no effect on structural deformation and fracture.
