【摘要】 作为新一代产品定义技术,基于模型定义(Model-Based Definition,MBD)将设计、制造、检验等制造过程中的全部信息集成于一个综合的产品模型中,并使之成为贯穿制造全过程乃至产品全生命周期的唯一数据源,从而为推进数字化环境下的设计制造检验一体化提供有力支撑。回顾了产品定义方法的发展历史,分析了MBD技术的发展及在航空制造领域的应用现状,探讨了MBD技术的发展方向。更多还原

【Abstract】 With the benefits of MBD(model-based definition), a new method for product definition, information from design, manufacturing and inspection can be integrated into a synthetic model to construct the unique data source throughout product manufacturing process. Recent years, MBD is playing a more essential role in modern manufacturing, especially in aeronautical industries. Based on a brief review of the development of production definition, the state-of-art of the MBD in aeronautical manufacturing is discussed in this paper. Additionally, the outlook of the future development and application of MBD is also proposed.更多还原
