针对500 kW海洋能示范工程的工程目标,以50 kW潮流能水轮机为例,结合实际海域的海洋环境资源条件,采用座底式支撑结构,应用水动力学软件对整个装置在实际工况下所受的海洋环境载荷进行数值模拟,参照海洋结构物设计规范对装置进行稳定性校核.借助AWE技术,对支撑结构在环境载荷作用下的静态、动态响应和可靠性进行有限元分析,分析结果对指导座底式潮流能水轮机设计具有一定的参考价值.“,”Considering the actual marine environmental conditions of the sea site where the tidal turbines were deployed,a seabed seated supporting structure was adopted for the 50 kW turbine units of a 500 kW marine energy demonstration project.The environmental load on the support structure was simulated by using CFD method and stability of the device was analyzed referring to marine structures design standards.Finite element analysis on static response,dynamic response and stability of the supporting structure was done by using software AWE d.Resuhs could be used for guiding the design of seabed seated tidal current turbines.
