基于多浮体运动响应计算方法,采用OrcaFlex软件,针对光伏电站漂浮方阵模型多浮体连接件刚度与其运动响应进行数值分析研究。首先,通过与有关浮体连接件试验进行对比,验证数值模拟的合理性;然后,开展对漂浮式光伏方阵在不同刚度连接件下多浮体六自由度运动的数值计算,对横纵浮体六自由度运动进行评估;最后,分析浮体间相对运动对连接件载荷之间的影响。研究结果表明：该研究模型随连接件刚度的增加,横向浮体整体运动响应大于纵向浮体,应更关注横向浮体的连接加强问题。连接件刚度较小时,浮体间的运动约束能力较差;刚度较大时,不利于抵抗浮体间的相互冲击,造成不必要的实际工程成本。
Abstract
Based on the calculation method of multi-body floating motion response, the OrcaFlex software is used to conduct numerical analysis on the stiffness and motion response of multi-body floating connectors aiming at the floating square array model of photovoltaic power station. The rationality of numerical simulation is verified by comparing with the floating body connection test. Then, the 6-DOF motions of multiple floating bodies with different stiffness connectors and numerically calculated, and the 6-DOF motions of horizontal and vertical floating bodies are evaluated. Finally, the influence between the relative motion of floating body and the load of connecting piece is analyzed. The results show that the overall motion response of the transverse floating body is greater than that of the longitudinal floating body with the increase of the stiffness of the connector, and more attention should be paid to the connection strengthening of the transverse floating body. When the stiffness of the connecting piece is small, the motion constraint ability between floating bodies is poor. When the stiffness is large, it is not conducive to resist the impact between floating bodies, resulting in unnecessary actual engineering costs.
