摘　　要：基于AQWA数值模拟软件,对影响波能发电装置动力特性的各参数进行了敏感性分析,提出关键参量用于优化设计。结合海域环境条件,构建结构动力特性优化目标,计算影响结构动力特性关键参量的临界值,并对结构进行优化检验。研究表明:影响结构动力特性的关键参量为张力锚缆刚度,增大张力锚缆刚度,避开共振区,结构运动参数减小显著。该研究结果可为振荡浮子式波能发电装置系泊系统优化设计提供参考。Based on the AQWA numerical simulation software,analyzing the sensitivity of the parameters of the dynamic characteristics of the Heaving Buoy Wave Energy Convertor,the key parameters are proposed for optimal design.In consideration of the environmental conditions of the actual sea area,the structural dynamic characteristics optimization proposes are put forward to calculate the critical value of the key parameters which affect the structural dynamic characteristics,and checks up the structure of optimal design.The result shows that the one of key parameters that affects the structural dynamic characteristics is the stiffness of the tension cable.As the stiffness of the tension cable is increased to avoid the resonance area,the structural kinematic parameters are reduced obviously.The results of this study can provide a reference for the optimization design of mooring system for heaving buoy wave energy convertor.
