梳理分析美国核潜艇研发领域近四十年来数字化技术的发展历程，将其划分为计算机辅助设计、三维并行协同设计、基于模型的系统工程、数字工程探索应用等4个发展阶段。总体上看，美国核潜艇研发数字化技术表现为由单项技术应用到研制全过程数字化贯通，再到装备全寿期数字化应用的演进过程，其应用范例可提供重要经验启示。
This paper analyzes the development of American nuclear submarine digital technology in the past four decades， divides it into four stages of development: computer-aided design, 3D parallel collaborative design, model-based systems engineering, and exploring digital engineering applications. The R&D of American nuclear submarine digital technology is an evolution process from the application of a single technology to the digital integration of the whole process, and then to the digital application of the equipment life cycle. Its application examples can provide important experience and inspiration.
