摘要

针对双浮体筏式波浪能转换装置开展浮体间距参数优化研究

系统探究规则波与不规则波作用下波长-浮体间距比对装置能量俘获性能及铰接受力的影响规律。通过运用数值模拟与模型试验方法

揭示波长-浮体间距比对系统性能的作用机理。研究发现：在规则波条件下

系统能量捕获宽度比呈现显著波长相关性

当波长-浮体间距比为0.25时达到峰值0.44

较波长间距比0.063工况提升46.1%;在不规则波条件下

合理调整浮体间距可使连接处水平向铰接力降低约75%

垂直向铰接力降低约25%

从而有效提升装置服役寿命;斜向入射波会导致能量捕获宽度比的非线性响应

当入射角为15°时系统获得最优能量捕获宽度比

较垂直入射工况提升22%。

Abstract

Focusing on the optimization of the spacing parameters of a dual-float wave energy conversion （WEC） device

systematically investigating the influence of the wavelength-to-float spacing ratio on the energy harvesting performance and hinge loads under both regular and irregular wave conditions. Through the application of numerical simulation and model trial methods

the working mechanism of the wavelength-to-float spacing ratio on system performance is revealed. The findings indicate that under regular wave conditions

the energy harvesting width ratio of the system exhibits a significant wavelength dependency

reaching a peak value of 0.44 when the wavelength-to-float spacing ratio is 0.25

which is a 46.1% increase compared to the case with a ratio of 0.063. Under irregular wave conditions

appropriately adjusting the float spacing can reduce the horizontal hinge load at the connection joint by approximately 75% and the vertical hinge load by about 25%

thereby effectively enhancing the service life of the device. Oblique incident waves induce a nonlinear response in energy harvesting width ratio

and the system achieves the optimal energy harvesting width ratio when the incident angle is 15°

which is a 22% improvement compared to the case of vertical incidence.
