软刚臂单点系泊系统横向刚度分析

Analysis of Transverse Stiffness of Soft Yoke Single Point Mooring System

对软刚臂单点系泊系统的横向刚度理论进行探讨,并以海洋核动力平台单点系泊系统为例进行相关计算,对海洋核动力平台在不同海洋环境条件下的水动力性能开展系统的风浪流水池模型试验。基于理论研究并运用MATLAB和Adams软件对软刚臂系统横向刚度进行分析计算,通过试验得到系统的横向回复力曲线,结果表明其刚度在横向位移较小时近似为一固定值(5t/m),并随横向位移增大而增大。

The theoretical study of transverse stiffness of soft yoke single point mooring system is studied,the single point mooring system of a marine nuclear power platform is taken as an example to carry out the relevant calculation,and the hydrodynamic performance of the marine nuclear power platform under different marine environment conditions is systematically tested in the wind,wave and water basin model.Based on the theoretical research and using MATLAB and Adams,the analysis and calculation of the transverse stiffness of the system are conducted,and the transverse restoring force curve of the system is obtained through the test.The results show that the transverse stiffness of the system is approximately 5 t/m as a fixed value when the transverse displacement of the system is small,and it increases with the increase of transverse displacement.
