船舶的结构设计直接影响到船舶的强度、刚度、稳定性等性能指标。传统的船舶结构设计方法主要依赖于经验和试验，存在着设计周期长、成本高、效率低等问题，而基于有限元分析的船舶结构设计方法可以通过数值模拟和优化算法来实现结构设计的自动化和优化，提高设计效率和设计质量。本文从船舶结构的极限强度理论和疲劳强度理论分别进行分析，并基于有限元软件进行船舶制造结构的设计仿真。
The structural design of a ship directly affects its performance indicators such as strength, stiffness, and stability. Traditional ship structural design methods mainly rely on experience and experimentation, which have problems such as long design cycles, high costs, and low efficiency. However, ship structural design methods based on finite element analysis can achieve automation and optimization of structural design through numerical simulation and optimization algorithms, improving design efficiency and quality. The article analyzes the ultimate strength theory and fatigue strength theory of ship structures, and conducts design simulation of ship manufacturing structures based on finite element software.
