摘要
为分析栈桥系泊系统和风、浪、流等环境因素对发电船水动力性能的影响,文章评估发电船系泊系统的安全性,合理设计发电船系泊系统,并建立发电船栈桥系泊数值模型。基于三维势流理论,应用AQWA软件对该船进行频域水动力性能分析,通过时域耦合仿真计算得到其六自由度运动响应、系泊缆张力和护舷压力,并对不同环境载荷下的船舶系泊系统进行安全校核。计算结果表明:在各作业工况下,发电船系泊系统是安全的;波高和浪向角对系泊缆的张力和运动响应有重要影响,波浪周期对纵摇和垂荡的影响较大。
In order to analyze the influence of trestle mooring system and environmental factors such as wind,wave and current on the hydrodynamic performance of power ship,the safety of the ship’s mooring system is evaluated,the mooring system is designed reasonably,and the numerical model for the mooring state of the ship is established.Based on the three-dimensional potential flow theory,the frequency domain hydrodynamic performance of the ship is analyzed by AQWA software.The response of six degrees of freedom,mooring line tension and fender pressure in time domain are obtained through time domain coupling simulation calculation,and the safety of the ship’s mooring system under different environmental loads is checked.The results show that the mooring system of the ship is safe under various working conditions.The wave height and wave direction angle have an important influence on the mooring line tension and motion response.The wave period has a great influence on pitch and heave.
