针对船舶轴系设计中长期存在的人工经验依赖性强、多船级社规范应用低效及CAE验证滞后等瓶颈问题，提出一种基于多规范融合的轴系集成化设计方法。通过构建规范-经验双驱动计算引擎（集成CCS/LR/DNV等六大船级社差异化公式与专家知识规则），实现轴系强度计算的智能化匹配与裕度量化；开发全参数化特征模板库（支持CATIA环境下的模型智能重构与自动出图），打通几何模型动态更新链路；建立标准化CAE接口（实现Nauticus校中仿真模型自动生成），形成覆盖“计算-建模-仿真”全流程的结构化数据链。实船应用表明：该方法可大幅减少人工干预，缩短设计周期70%，确保符合规范的同时显著提升设计质量与效率。
To address long-standing bottlenecks in marine shafting design, such as heavy reliance on manual experience, inefficient application of multi-class rules, and delayed CAE verification, this paper proposes an integrated design methodology based on multi-specification fusion. A rules-experience dual-driven computation engine is developed, which integrates differentiated formulas from six major classification societies (e.g., CCS, LR, DNV) with expert knowledge rules. This engine facilitates intelligent matching and margin quantification for shafting strength calculations. A fully parametric feature template library is constructed to enable intelligent model reconstruction and automated drafting within CATIA environments, thereby establishing dynamic geometric update pathways. Furthermore, a standardized CAE interface is implemented to automate the generation of Nauticus alignment simulation models. These components collectively form a structured data pipeline that covers the entire "calculation-modeling-simulation" workflow. Practical vessel applications demonstrate that the proposed methodology drastically reduces manual intervention, compresses the design cycle by approximately 70%, ensures regulatory compliance, and significantly enhances both design quality and efficiency.
