针对深远海漂浮式光伏缺乏成熟浮体阵列类型，且其多体系统核心受力部件连接器研究不足现状，本文提出一种多体运动与动力耦合分析方法，以实现连接器产品方案的优化设计和性能评价。研究中，采用多体动力学机械系统动力学自动分析(Automatic dynamic analysis of mechanical systems, ADAMS)软件，构建了深水柱式光伏阵列刚柔耦合虚拟样机。将典型海况下光伏平台时域运动响应作为驱动施加给样机，完成连接器从水动力分析球铰力学概念到产品设计三维实体模型的高效数值仿真。根据连接器动态应力响应分布特征，融入多目标优化和多准则决策方法，得到了最优设计方案。结果显示，该优化方案可以使单个连接器的用钢量减少5.52%。因此，本文所提出的基于虚拟样机技术的漂浮式光伏阵列连接器分析方法可为海上复杂多体系统部件优化设计提供参考。
Abstract：In view of the lack of mature floating body array type for deep-sea floating photovoltaic(PV), and the insufficient research on the core force components of the multi-body system's connectors, this paper proposes a multi-body motion and dynamic coupling analysis method to realize the optimal design and performance evaluation of the connector product scheme. A deep-water vertical cylinders' photovoltaic array rigid-flexible coupling virtual prototype is constructed through the multi-body dynamics software ADAMS(Automatic Dynamic Analysis of Mechanical Systems). The time-domain motion response of the PV platform under typical sea conditions is applied to the prototype as a drive, and the efficient numerical simulation of the connector from the hydrodynamic analysis of the ball-hinge conceptual model to the three-dimensional solid model of the product design is completed. Based on the dynamic stress response distribution characteristics of the connector, a multi-objective optimization and multi-criteria decision-making approach is integrated to obtain the optimal design solution, resulting in a 5.52% reduction in steel consumption for a single connector. The proposed analysis method for floating PV array connectors based on virtual prototyping technology in this paper can serve as a reference for optimizing the design of offshore complex multi-body system components.
