漂浮式海洋能平台运动响应耦合预报研究

         

摘要

随着海洋工程向远海发展,漂浮式海洋能平台的运动响应预报问题成为研究的热点之一.本文以漂浮式海洋能平台为研究对象,首先基于间接时域法,建立浮式平台时域运动方程,然后基于悬链线理论和全矢量形式的三维集中质量法,建立系泊系统运动方程.在使用自行开发的计算程序对以上方程进行求解获得初值后,以系缆和浮式平台的受力和位移作为2个运动方程的交互输入与输出,建立浮式平台与系泊系统的全耦合计算方法.最后对简化的浮式海洋平台进行计算,分析载体平台的运动响应和系缆受力情况.本文可为解决相关工程问题提供参考和借鉴.%With the development of ocean energy engineering to open sea, the coupling prediction of ocean platform motion response is becoming one of the hotspots. In this paper, a floating ocean platform is taken as the study object, and the motion response of the floating platform and the mooring system in wave is calculated and analyzed by full coupling method. Based on the indirect time domain method, this paper establishes and solves the time domain motion equation of the floating platform, and computes the time domain motion equation numerically. The motion equations of the mooring system are es-tablished and solved based on the theory of catenary equations and the three-dimensional mass method in full vector form. Finally, the full coupling calculation method of the platform and mooring system is proposed, the force and displacement of the mooring and floating platforms are taken as the input and output of two motion equations in each calculation step. A sim-plified floating platform is calculated and the motion response of the platform and the force of the cable are analyzed. This paper can be a reference for solving related engineering problems.
