| 摘 要： | 建立软刚臂系泊系统的理论模型以及6自由度静恢复力特性计算分析的数学模型,模拟实际几何关系与力学作用机制。提出基于误差判断的变步长迭代搜索的数值逼近求解方法,以QHD32-6 FPSO软刚臂系泊系统的纵向和横向水平恢复力特性为例进行数值预报,并与国外设计公司计算结果以及模型试验结果进行比较分析。对比显示,该模型的数值计算结果符合良好,而且迭代计算次数少、收敛快、误差小,可用于海上软刚臂系泊系统静恢复力特性的预报。

| Abstract: | A theoretical model and basic geometric and force equations of a soft yoke mooring system are established to simulate the geometric properties and interaction mechanism with FPSO.Then a numerical iteration algorithm based on error estimation is developed and used to calculate the horizontal restoring characteristics of the soft yoke moored QHD32-6 FPSO system.The numerical results of surge and sway restoring characteristics are compared with the results provided by the foreign designer and the model test.It is shown that the numerical simulation takes only a few iteration times and the errors are very small.Furthermore,the agreement of comparisons is quite good.Therefore,the present theoretical model and numerical iteration algorithm are efficient and reliable for prediction of the horizontal restoring characteristics of a soft yoke mooring system. |
