摘　　要：以“澎湖号”半潜式波浪能养殖平台为研究对象,采用基于1阶泰勒展开边界元法的中国数值水池软件,建立增加等效波浪载荷面积模拟生物附着的简化仿真方法,对6种生物附着覆盖面积率下的养殖平台频域运动响应进行分析。作为对均匀分布假设的修正,同时给出2种生物附着不均匀分布的模型,并将其计算结果与均匀分布模型的计算结果相对比。结果显示,网衣生物附着对平台横荡和垂荡2个自由度运动特性的影响显著,运动幅值最多增大10%左右,横荡2阶力增幅可达115.97%。Taking the "Penghu" semi-submersible wave energy aquaculture platform as the research object, a simplified simulation method for increasing the equivalent wave load area to simulate biological attachment is established by using the China Numerical Tank software, which based on the first-order Taylor expansion boundary element method, and the frequency domain motion response of the aquaculture platform under six biological attachment coverage areas is analyzed. As a correction to the hypothesis of uniform distribution, 2modified models of uneven distribution of biological attachment are given, and their calculation results are compared with those of uniform distribution model. The results show that the increase of biofouling coverage area has a significant impact on the motion characteristics of the platform in 2 degrees of freedom: sway and heave, which can increase the motion amplitude by about 10%, and the increase of the second-order force of sway can reach 115.97%.
