摘要：

作为海洋牧场的核心装备，养殖平台在促进渔业可持续发展和海洋生态修复方面具有重要作用，同时可搭载开发海上风能、波浪能等清洁能源，为远海生产活动提供能源供给。本文基于势流理论、有限元分析方法和线性累积损伤理论，在传统研究的基础上将网衣结构纳入计算，进行箱体式养殖平台的水动力分析，并利用随机性设计波法对自行研制的箱体式养殖平台完成波浪载荷计算和安全验证。研究结果表明：10种典型控制载荷中，最大分离力对于平台结构屈服强度的影响最为显著，且应力峰值集中在网衣支撑结构与主结构连接位置；平台支撑杆与主结构连接位置、肘板趾端相较于其他区域，更易发生疲劳损伤；在网衣桁架与主结构连接处的肘板趾端结构区域，结构的疲劳特征一致，建议在未来研究中进行归类处理以简化计算。最终，箱体式养殖平台在生存工况下的屈服、屈曲和疲劳强度均满足安全要求。其中，平台大部分位置的屈曲利用率小于0.5，显示出较高的屈曲安全裕度和良好的抗压承载性能。本文研究可为养殖平台的安全设计和稳定运行提供理论依据。

Abstract:

As core equipment for marine ranches, aquaculture platforms play a vital role in promoting sustainable fisheries and restoring marine ecosystems. They also offer potential for integrated clean energy systems, such as offshore wind and wave power, which can supply energy for offshore operations. Building upon traditional research, this paper incorporates net structure calculations into hydrodynamic analysis of box-type aquaculture platforms using potential flow theory, finite element methods and linear cumulative damage theory. Utilizing a random design wave approach, wave load calculations and safety verification were performed for a self-developed box-type aquaculture platform, providing theoretical foundations for its safe design and stable operation. Research findings demonstrate that among 10 typical dominant load conditions, the maximum separation force exerts the most significant impact on yield strength, with stress concentrations observed at the connections between the net-supporting structure and the main platform frame. Compared to other regions, the joints linking platform bracing members to the main structure, along with the toe ends of gusset plates, are more prone to fatigue damage. The fatigue behavior of gusset plate toe regions where the net truss connects to the main structure is consistent across analogous locations. To simplify future analyses, it is recommended that these areas be grouped into categories for assessment. Ultimately, the box-type aquaculture platform met safety requirements for yield strength, buckling strength, and fatigue strength under operational conditions. The buckling utilization ratio was less than 0.5 at most platform locations, indicating a high buckling safety margin and excellent compressive load-bearing performance. This study provides a theoretical basis for the safe design and stable operation of aquaculture platforms.
