摘要
运用三维势流理论和Morison公式相结合的数值计算方法分析筒型平台的运动响应和波浪载荷特点,采用Morison公式计算平台舭部阻尼板结构的波浪力;对于大尺度结构,波浪载荷采用线性绕射理论进行计算,分析表明,该圆筒型海洋平台的波浪力和运动响应计算结果可直接用于结构设计.
The wave load and motion response of a cylindrical platform is analyzed by boundary element method combined with Morison＇s equation. The Morison＇s equation is applied for bilge damp structures and the 3D potential theory is used for large volume structures. Based on analysis of numerical results, the properties of motion and wave loads of cylindrical platform presen- ted can be served as inputs for the structure design.
