液压辅助蓄能吸收式波浪能装置系泊系统的研究

本项目通过对传统波浪能装置系泊系统的分析比较，基于提高波浪能装置捕获波浪能能力和丰富波浪能捕获途径多样性，提出一种利用波浪能装置二阶低频漂移运动做功捕获波浪能的新方法；基于波浪能装置抗大浪极端海况保障其生存稳定性提出能量吸收式系泊系统设计新方法。基于以上两个目标，本项目首先提出并设计一种新型液压辅助蓄能吸收式系泊系统；然后通过Cummins时域方法对非线性系泊系统和波浪能装置的耦合运动建立力学方程求解，并通过改变系泊布置方式、系泊设计参数优化设计，获得最优系泊方案；最后开展模型试验，根据相似原理将试验数据与理论计算数据对比验证本项目的理论合理，技术可靠。

The project presents an analysis of the conventional mooring system which have been identified as a question to keep the wave energy converters(WEC) on station in the most severe storm conditions and to capture more wave energy. Therefore, the concept of energy absorption WEC mooring system is proposed in order to guarantee the mooring safety in severe storm conditions and the concept of assisted capture wave energy WEC mooring system is proposed in order to enrich wave capture approach and get more wave energy. Based on above two goals, firstly the novel design of Assisted Hydraulic Energy-Storage Absorption WEC Mooring is created; secondly the coupling motion equation of the WEC and mooring is established and then optimizing design scheme by changed the mooring configurations and parameter; lastly to carry out the model test by the principle of simulate and then analyzing the data to verify the research of Assisted Hydraulic Energy-Storage Absorption WEC Mooring.
