本文对船舶的航行过程进行分析,构建船舶的运动数学模型,并对船体的下沉量进行分析。基于CFD技术对船体下沉量进行数值分析,并给出船舶阻力数值模拟曲线和船舶下沉量数值模拟曲线,同时对船舶下沉量和流速之间的关系进行探讨;利用线性回归的方法对船舶的下沉量进行预测,对船中和船尾的下沉量和船体初始纵倾角之间的关系进行线性回归拟合预测。
This article analyzes the driving process of ships, focusing on constructing mathematical models of ship motion and analyzing the sinking amount of the ship. Based on CFD technology, numerical analysis of ship sinking was conducted, and ship resistance numerical simulation curves and ship sinking numerical simulation curves were provided. At the same time, the relationship between ship sinking and flow velocity was explored. Using linear regression method to predict the sinking of ships, with a focus on linear regression fitting prediction of the relationship between the sinking of the ship's middle and stern and the initial longitudinal inclination of the ship.
