| 摘 要： | 针对具有天然岛礁庇护或人工庇护的温和海洋环境,提出了一种混合模块大型浮式结构系统,即水动力性能更优的半潜式模块作为内侧主模块,消波效果更优的箱式模块作为外侧浮式防波模块和波浪能发电模块.波浪能装置利用外侧箱式模块与内侧半潜式模块的相对纵摇运动进行发电.考虑模块间多体水动力耦合效应和连接器机械耦合效应,基于ANSYS-AQWA程序重点研究了典型海况下混合5模块串联浮式结构系统的动力响应特征.结果表明,外侧箱式模块和波浪能发电装置能有效减弱内侧半潜式主模块运动响应、连接器动力响应和系泊缆绳张力,并且提供一定的能源供给.所得研究成果可为模块化超大型浮式结构系统的防波—发电集成系统设计提供参考.

| Abstract: | A large floating structure system with hybrid modules is preliminary designed for the mild marine environment with natural island shelter or artificial shelter in the present work. The structure is composed of a number of semi-sub modules inside with better hydrodynamic performance treated as main modules and some box-type modules outside used as floating breakwater modules and wave power generation modules. The wave power production is achieved through the relative pitch motion of the adjacent box-type modules and semi-sub modules. This dynamic response characteristics of a hybrid 5-module tandem floating structure system are studied under typical sea conditions based on ANSYS-AQWA program. Both the hydrodynamic interaction effect and the mechanical coupling effect have been taken into consideration. The results indicate that the outer box-type modules and the wave power generation devices can effectively reduce the motion of the inner semi-sub modules, the load of the connectors as well as the mooring line tension, and also provide considerable energy. The main results of the study can provide guidance for the integration design of breakwaters and wave power generation in modularized VLFS. |
