摘　　要：薄膜式光伏平台具有结构质量轻、湿表面面积大的结构特性,在迎浪拖航时极易产生速度的快速变化,进而导致拖缆的较大瞬时张力,给拖航施工带来了一定的困难。针对这一问题,分别采用CFD与势流方法对流载荷与波浪载荷进行预报,在此基础上利用OrcaFlex软件建立了薄膜式光伏平台拖航时域分析模型,针对迎浪迎流状态下不同航速的薄膜式光伏单平台及双平台两种拖航方案下的拖航动力响应展开了模拟。结果表明,在迎浪迎流条件下,双平台拖航方式相较单平台拖航具有更好的平均阻力特点与动力响应特性。同时,适当地提高拖航速度可有效降低因平台随波浪反向运动而导致的瞬时拖缆载荷最大值。研究成果可为薄膜式光伏平台拖航提供一套运动响应预报方法,并为薄膜式光伏平台拖航方案的制定提供参考。The membrane-type photovoltaic platform features a lightweight structure with a large wet surface area,which can lead to rapid changes in speed during wave-facing towage,resulting in significant instantaneous tension in the towing cable and posing challenges to towing operations.To address this issue,both computational fluid dynamics(CFD)and potential flow methods were utilized to forecast the hydrodynamic and wave loads.Based on this analysis,a time-domain analysis model for towing the membranetype photovoltaic platform was established using OrcaFlex software.Simulations were conducted for both single-platform and doubleplatform towing scenarios at different speeds under head-on wave and current conditions.The results indicate that,under these conditions,the double-platform towing method exhibits superior average resistance characteristics and dynamic response properties compared to the single-platform towing method.Additionally,an appropriate increase in towing speed can effectively reduce the maximum instantaneous cable load caused by the platform's reverse motion due to wave action.The findings of this study provide a predictive method for the motion response of membrane-type photovoltaic platforms during towing and offer a reference for the development of towing strategies.
