摘要
随着船舶规模的增大,如何检测和评估船舶结构的状态和强度已成为一个紧迫的问题。本文基于集装箱船舶结构状态检测系统所收集到的船舶在风浪中的应力数据,分析了集装箱船舶在风浪中经历的船体受力特征。在船体重要区域的应力特征的基础上,建立了评价模型来评估整个船体在风浪中受外载荷影响的程度。使用该评价模型对比分析了风浪中不同航向的船体应力特征,得出了船舶在抗风浪方面的可选航向范围和风浪中的航线规划策略。
As ship sizes continue to increase,the detection and evaluation of structural conditions and strength have become pressing challenges.This study utilizes stress data collected by the structural condition monitoring system of container ships operating in wind and waves to analyze the hull loading characteristics under such conditions.Based on stress characteristics in critical hull regions,an evaluation model was developed to assess the extent of external load impacts on the entire hull in wind and wave environments.Using this evaluation model,a comparative analysis of hull stress characteristics across different headings in wind and waves was conducted,leading to insights into feasible heading ranges and route planning strategies for wave resistance.
