【摘要】：精确评估模块连接处荷载特性对超大型浮体的水动力设计及结构安全性研究具有重要的工程意义。文章以5模块半潜式超大型浮体为研究对象,考虑碰撞荷载和风、浪、流环境荷载的联合作用并采用AQWA软件对超大型浮体模块连接点处的受力特性开展了数值计算。船舶碰撞荷载简化为矩形脉冲,采用定常风、定常流以及JONSWAP波谱,探讨了船舶碰撞角度、撞击位置、环境荷载等因素对模块连接点受力特性的影响。该文的研究成果可为事故荷载作用时超大型浮体连接器结构设计和强度计算提供一定依据。
[Abstract]:Accurate evaluation of load characteristics at the connection of modules is of great engineering significance to the hydrodynamic design and structural safety study of super-large floating bodies. This paper takes 5 modules semi-submersible super-large floating bodies as the research object, considering the impact load, wind and wave. The combined action of the current environment load and the numerical calculation of the force characteristics at the connection point of the super-large floating module are carried out by using AQWA software. The ship collision load is simplified to a rectangular pulse, and the steady wind, steady current and JONSWAP spectrum are used. The effects of ship collision angle, impact position and environmental load on the mechanical characteristics of the connection point of the module are discussed. The research results in this paper can provide a certain basis for the design and strength calculation of the superlarge floating connector structure under the action of the accident load.
