摘要
本文介绍了自升式平台系泊系统模型建立及其分析的基本原理,并应用ANSYS软件的workbench平台Hydrodynamic Diffraction及Hydrodynamic Time Response模块,以某自升式平台的系泊定位系统为例,进行了数值模拟和分析,得到了平台的动态响应。研究了在给定的风、浪、流联合载荷的极端工况作用下,平台和系泊缆绳耦合状态下的时域运动响应分析,得到了系泊缆绳的系泊力以及平台位移的时历曲线。通过分析,得出了一些对自升式平台作业区域系泊定位时有一定实际应用价值的结论。
Jack-up platform is introduced the establishment of mooring system model and the basic principle of analysis, and applied Hydrodynamic Diffraction and Hydrodynamic Time Response module of ANSYS workbench platform, with mooring positioning system of a jack-up platform as an example, numerical simulation and analysis,then get the dynamic Response of the platform. Study on the extreme conditions in wind, wave, lfow combined load is given, the response analysis in the time domain coupled state of motion platform and mooring lines under the mooring lines, mooring force and displacement time history curve of the platform are obtained. Through the analysis of jack-up platform mooring positioning operation area has a certain practical application value.
