国际海洋贸易的不断发展，对海上运输时效提出了新的要求，船舶的运营航速亟待提高。然而，高速航行下的船舶承受更大的波浪载荷，为保证船舶安全，在船体结构强度设计时要充分考虑船体航速提升带来的波浪载荷的影响。本文以某一集装箱船为研究对象，采用自研的海洋结构分析通用软件SAM，计算船舶在不同航速下的运动和载荷响应。通过与模型试验结果对比，验证了计算软件的准确性。在此基础上，分析不同横剖面位置垂向弯矩载荷随浪向和航速变化的规律。研究成果可为船舶结构强度设计方案的制定提供参考，保证船体结构安全。
The continuous development of international maritime trade requires for the new limitation of marine transportation, the ship speed needs to be improved urgently. However, ships with higher speed will encounter greater wave loads. In order to ensure the safety of ships, the influence of wave loads caused by the increase of ship speed should be fully considered in the hull structure strength design stage. This paper takes the container ship as the research object., the motion and load response at different speeds are calculated by using the self-developed marine structure analysis. general software SAM. The accuracy of the software is verified by comparing with the model test results. On this basis, the cross section vertical bending moment load is analyzed with wave direction and speed The research results can provide a reference for the formulation of the structural strength design scheme of the ship and ensure the safety of the hull structure.
