【摘要】：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。
[Abstract]:Based on linear wave theory. A semi-analytical model of first-order wave force and moment of cylindrical buoy with holes is established by using the method of matching double eigenfunction expansion. The model can also be extended to cylindrical buoy without skirt or vertical drift of water surface. Floating cylinder. Submerged vertical cylinders and submerged perforated / solid circular sagging plates. To verify the correctness of the calculation program. The vertical wave forces acting on submerged / solid circular sagging plates are compared with the semi-analytical results in literature, and the results are in good agreement. The influence coefficient of perforation of thin plates increases with the increase of perforation ratio. The effect of the opening ratio on the first order wave force and torque on the submerged circular hole swinging plate and the cylindrical buoy with an open hole skirt plate is discussed. The vertical wave forces and torques acting on submerged swaying plates decrease with the increase of opening ratio. The vertical wave force acting on a cylindrical buoy with a skirt plate increases with the increase of the opening ratio, and the effect of the opening ratio of the skirt plate on the torque on the cylindrical buoy with a skirt plate is greater than that on the wave force.
