摘　　要：在箱型超大型浮体迎浪端引入水下减振平板,依据势流理论,采用模态展开法和特征函数展开法求解流体速度势,并将其代入水弹性运动方程,求解该浮体的水弹性响应。探究减振板板宽、入水深度等参数对超大型浮体水弹性响应的影响;对比有无配置减振板情况下,入射波波长变化对浮体水弹性变形的影响,这些为今后的工程应用提供了理论依据。A submerged horizontal plate attached at the fore-end of the pontoon type of VLFS is introduced in this paper. The whole model is analyzed rigorously based on linear potential theory. Mode function expansion method and eigenfunction expansion method are employed to solve velocity potential. Wave-induced responses can be obtained by solving hydroelastic equation. Relationships between submerged plate parameters and wave-induced responses of VLFS are discussed. The structure attached submerged plate is compared with the one without plate attached, while hydroelastic deformation is calculated for a variety of wavelength values. The results will provide a theoretical basis for future design.
