水面气浮筒平台运动响应分析

摘要

推导浮动平台主体与浮筒受到的波浪力以及浮筒对平台的气浮力,建立水面浮动平台的水动力方程.考虑到浮筒与浮动平台主体间的耦合关系,对浮筒与平台主体的连接方式进行研究,分析弹性连接对浮动平台主体的影响.简化水面浮动平台系统的结构,构建三维几何模型,利用水动力仿真软件AQWA对平台系统的横摇和垂荡运动进行预测.%For a water surface floating platform system,the wave force and air supporting force are analyzed,and the floating platform hydrodynamic equation is established.Considering the coupling effect between multi-body and main platform,the connection method is studied,and the elastic connection influence is analyzed.the platform structure is simplified,and the platform system geometric model is built.The roll and heave motions are predicted by a hydrodynamic simulation software AQWA.
