|
摘要
海洋工程中系泊缆索、立管和张力腿等按其特性属于柔性构件范畴,进行柔性构件的分析方法研究对系泊系统的合理设计、保障海洋平台的作业和安全具有重要意义。本文研究了海洋工程柔性构件静力分析和动力响应的计算方法,并对耦合时域分析进行了研究。
首先,对悬链线方程进行进一步的计算,提出两段悬链线对接的理论模型对单点系泊系统系泊缆绳和锚链初始形状进行分析,并编制了计算程序,可用于计算柔性构件初始形状和预张力。
其次,研究了柔性构件非线性动力响应计算模型和方法,应用三维细长杆件力学模型对空间三维大变形杆件的非线性有限元模型和时域分析进行了研究。
最后,对考虑耦合效应下柔性构件的动力响应进行了研究。浮体应用六自由度运动刚体模型,柔性构件的非线性动力响应用三维细长杆件理论和有限元方法进行分析,耦合点处应用轴向和转动双弹簧模拟。根据研究结果和实际海况资料,应用HARP程序对卡拉奇港单点系泊系统工程实际进行了耦合分析。
Mooring cables, risers and tension legs, etc, all belong to the flexible components of offshore structures based on their characteristic. To research analysis methods of these structures are very significant for reasonable design of the mooring system and ensuring the platforms working and safety. Therefore, the appropriate calculation methods for static analysis and dynamic response of the flexible components of offshore structures have been studied in this thesis, including analysis of couple calculation in time domain.
Firstly, make further calculation of the catenary equation. A calculation model by connecting two segments of catenary equations has been developed to computing initial deformation of floating hawsers and mooring chains of the single point mooring system. According to the research, a program has been compiled that is suitable for calculating the initial position and pre-tension of flexible structures.
Additionally, the nonlinear dynamic response of the flexible components has been studied and simulated. A three-dimensional elastic rod theory is adopted to research nonlinear finite element model of the large deformation of space three-dimensional flexible structures, as well as the time domain analysis.
At last, the nonlinear coupled response of the floating structure and mooring system has been researched. The floating structure is modeled as rigid body with six degree of freedom, and the mooring line dynamics is modeled using rod theory and finite element method. The connections between mooring lines and platform are modeled as linear and rotational springs and dampers. The time-domain coupled analysis of the single point mooring system which is parked at Karachi port has been done using HARP program based on research results and reality oceanic conditions.
