江海通达船极限强度及影响参数的研究

摘要

This paper presentes the study on the ultimate strength for river-to-sea ship. According to simi-larity principle, a experimental model was designed, the corresponding experiment was carried out and the load-deflection curve was obtained, the experimental results is of important reference value in the research of ultimate strength. Nonlinear FEM method (ABAQUS) and the collapse method (Mars2000) are adopted to Numerical Simulation analysis, compared with the trail results, the reasonability of the software was proved. The software of ABAQUS was used to study the precision of the ultimate strength calculation and the gen-eral law of the ultimate strength, which will provide reference for structure’s optimal design of the ship.%文章针对江海通达船作了极限强度研究。根据相似原则设计出了试验模型，并进行了相应的试验研究，得出了相应的载荷—挠度曲线，试验研究结果对极限强度研究具有重要的参考价值。同时采用非线性有限法（ABAQUS）和逐步崩溃分析法（Mars2000）进行数值模拟分析，与试验值进行对比，验证了软件的合理性。同时利用ABAQUS软件研究了影响极限强度计算精度的因素和极限强度的一般规律，可为船舶结构优化设计提供参考。
