Abstract:
The floating photovoltaic membrane prototype developed by Ocean Sun was selected as a reference object, and a 1∶40 scale laboratory model was designed and produced to further explore the impact of inflow conditions on the hydrodynamic properties of the membrane structure. By conducting free attenuation tests, results showed that the inflow has only a slight effect on the natural frequencies of the heave, pitch, and surge of the membrane structure. This finding shows that the dynamic properties of the membrane structure remain essentially stable under different inflow conditions. The results of further regular and irregular wave hydrodynamic experiments show that, compared with the control group, the response of the membrane structure under inflow conditions in terms of heave, pitch, surge, and heave acceleration motions is relatively gentle, whereas the response of the membrane structure to the mooring force is strong. Especially when the waves are irregular, the inflow conditions have a more significant impact on the membrane structure, which may lead to more complex response changes in the structure. Therefore, in the actual engineering design process, the impact of inflow conditions on the behavior of the membrane structure must be fully considered, and appropriate engineering measures must be taken to ensure the safety and stability of the structure.
选择Ocean Sun公司开发的浮动光伏膜结构原型作为参考对象, 设计并制作了1∶40比例的实验室模型, 旨在深入探讨流入条件对膜结构的水动力学特性的影响.自由衰减测试结果显示, 流入量对膜结构的垂荡、纵摇和纵荡的固有频率几乎没有影响.这表明在不同的流入条件下, 膜结构的动态特性基本保持稳定.进一步进行的规则波和不规则波水动力实验结果表明, 相较于对照组, 流入条件下的膜结构在垂荡、纵摇、纵荡以及垂荡加速度运动方面的响应较为平缓, 但系泊力较大.特别是当波浪为不规则波时, 流入条件对膜结构的影响更加显著, 可能导致结构的响应变化更加复杂.因此, 在实际的工程设计过程中, 必须充分考虑流入条件对膜结构行为的影响, 并采取适当的工程措施来确保结构的安全性和稳定性.
