本文基于逐步破坏方法，以某船模型结构为研究对象，开展弯曲载荷作用下船体结构极限强度计算分析。同时采用Abaqus数值仿真软件，开展某船结构弯曲极限强度数值仿真分析。通过本文的研究，获得该结构极限承载能力以及失效模式等，为某船结构设计提供技术支撑。
Based on the stepwise failure method, this paper takes a ship model structure as the research object to carry out the calculation and analysis of the ultimate strength of the hull structure under bending loads. At the same time, the Abaqus numerical simulation software is used to numerically analyze of the longitudinal ultimate strength of ship structures. Through the research of this article, the ultimate bearing capacity and failure mode of the structure are obtained, which provides technical support for the design of a ship's structure.
