基于线性波理论,应用匹配双特征函数展开法建立了含开孔裙板之圆柱形浮标一阶波浪力和力矩的半解析计算模型.该计算模型还可推广应用于无裙板之圆柱形浮标或水面垂直漂浮圆柱体、淹没垂直圆柱体及淹没开孔/实心圆形垂荡板.为了验证计算程序的正确性,将作用在淹没开孔/实心圆形垂荡板上的垂向波浪力与文献的半解析结果进行了比较,结果吻合很好.薄板的开孔影响系数随开孔率增大而变大,讨论了开孔率对作用在淹没圆形开孔垂荡板及含开孔裙板之圆柱形浮标上一阶波浪力和力矩的影响.结果表明,作用在淹没垂荡板上的垂向波浪力和力矩随着开孔率的增大而减小;而作用在含裙板之圆柱形浮标上的垂向波浪力则随开孔率的增大而增大.裙板开孔率对含裙板之圆柱形浮标上力矩的影响要大于对波浪力的影响.%Based on the linear water wave theory,an analytical model of first-order wave exciting forces on a cylindrical buoy with a porous skirt is established by means of the matched double eigenfunction-expansion method.In order to validate the program,the present solution of the vertical wave forces on a submerged horizontal porous/solid disk is compared with the published data,and good agreement is shown.The parameter of porous-effect G will be increased with the increase of porosity.Influences of the parameter G on the first-order wave exciting forces are discussed for the submerged horizontal porous disk and the cylindrical buoy with porous skirt respectively.It is found that both vertical wave force and moment on a submerged horizontal porous disk will be decreased with increasing porosity.The vertical wave force on the cylindrical buoy with a skirt will be increased as the parameter G of the skirt increases.The effect of the parameter G on the moment will be larger than that on the wave forces.
