摘要
基于势流理论建立浮体的水动力运动方程,并以该运动方程为基础对不同外形参数的浮子进行建模仿真,研究单个振荡浮子在频域下的水动力性能。主要利用水动力分析软件AQWA分析浮子底部形状、直径、吃水和重心位置变化对浮子RAO、波浪激励力、辐射阻尼系数、附加质量等水动力参数的影响,并与最近相关文献的结果进行对比。发现圆柱底浮子的性能较优,且相对浮子半径和阻尼的影响,浮子重心改变对于垂荡运动影响较小,相关计算结果可为浮子结构优化及阵列的分析提供指导。
The motion equations of oscillating buoys are established based on the potential flow theory,and different shape buoys shapes are modeled to simulate and calculate the hydrodynamic properties of the single float in the frequency domain.AQWA is mainly used to compare the effect of the bottom shape,diameter,draft,center of gravity position of buoys on the RAO,wave excitation force,radiation damping,added mass.The results are compared with that of previous study.It is found that the performance of the cylindrical bottom of the float is excellent,and the changes of the center of gravity have less effect on heaven motion than the effect of damping and the radius of buoys,which provides the guide for the structure optimization and array analysis of the floats.
