【英文论文摘要】 A 3D time domain method has been further developed to compute wave interaction with bodies.In this work,the problem is solved by using transient time domain Green's function.By applying the 3D time domain method,we investigate the gap influence on the wave forces for three-dimensional multiple floating structures.Special hydrodynamic resonance due to small gaps between multiple floating structures on wave forces is examined.Strong and complicate hydrodynamic interactions between the floating bodies are observed.Also,we computed added mass and damping coefficients of S175 hull.The computed results were compared with the other solutions and experimental results,the efficiency and reliability of the method was demonstrated.水利论文rc/n;~R,R'm
