深海采矿船平台与硬管连接点的弯矩计算方法
|
摘要
对一艘由6 500 t甲板船改造成的采矿船平台及硬管结构建立仿真计算分析模型,运用AQWA水动力软件完成RAO预报,使用Orcaflex软件计算出三级海况下采矿平台与硬管连接点的最大弯矩。计算中把复杂的耦合问题用线性波浪理论处理,取得了比较好的效果。
The simulating calculation and analysis model of the mining ship platform and hard pipe structure transformed from a deck ship of 6 500 t is established. The RAO prediction is completed by using AQWA hydrodynamic software. Using Orcaflex software, the maximum bending moment of the mining platform and hard pipe connection under three stage sea state is calculated. The complex coupling problem is treated with linear wave theory in the calculation, which gets a better effect.
