【英文论文摘要】 Hydrodynamic force of heave damping plats with different porosity and the solid circular plats are studied and successful simulated.Numerical results of the resistance coefficients and added-mass coefficients are obtained in this paper,and the influences of the porosity on the resistance and assed-mass coefficients are also investigated.These results will give some useful help for the optimization design and effect improvement of the have damping plats of deep sea spar platforms.
