摘　　要：为推动中国波浪能装置深远海发展的进程,本文以基于悬链式系泊的双浮体波浪能装置为研究对象,采用AWQA软件与WEC-Sim软件相结合的手段,首先通过物理模型试验数据验证数值模型的准确性,进而对装置施加常值动力输出(Power take-off,PTO)阻尼力,探究了装置在规则波作用下的水动力特性与获能。研究结果表明:本文提出的装置适用于中国海域中周期较短且波高较小的环境;装置的能量捕获特性在不同质量比配置下存在显著差异,需根据海域波况配置最优质量比;PTO阻尼力的改变不影响装置最优获能区间,但不同周期对应的最优阻尼力差距较大;不同波况条件下,锚链受力差距较为明显。In order to promote the development of wave energy devices in China's deep sea,this paper takes a double-floating wave energy device based on a suspended chain mooring as the research object,and adopts a combination of AWQA and WEC-sim to first verify the accuracy of the numerical model by physical model test data,and then applies constant value PTO damping to the device,and explores the hydrodynamic characteristics and energy gain of the device under the action of regular waves.The results show that:the proposed device is suitable for the short periods and small wave heights in China;the energy acquisition characteristics of the device vary significantly under different mass ratios,and the optimal mass ratio needs to be configured according to the wave conditions of the sea;the change of the PTO damping value does not affect the optimal energy acquisition interval of the device,and the difference of the optimal damping corresponding to different periods is large;The difference in force on the anchor chain between wave conditions and settings is significant.
