数字样机在飞机数字化协同研制中的发展

Development of Digital Mockup in the Aircraft Digital Cooperation

飞机数字样机是飞机产品的数字化表述,是与飞机相关的所有三维数字信息构成的产品模型集合,可用于工程设计、工程分析(空间分析、运动分析、拆装模拟、加工制造和维护检测)、工程仿真等活动。飞机数字样机的出现从根本上革新了传统飞机协同研制方式,开创了飞机数字化协同研制的新阶段,随着数字化技术、计算机网络技术的不断发展,数字样机在飞机数字化协同研制中的作用和地位也不断发展。从飞机数字化协同研制的发展历程出发总结论述了数字样机的发展历程。

The DMU （ Digital Mockup ） is a digital representation of aircraft products, which is a product model consisting of all 3D digital information related to the aircraft. It can be used for engineering design, engineering analysis （ space analysis, movement analysis, assembly and disassembly simulation, manufacturing and maintenance inspection）,engineering simulation, etc. The DMU radically reformed the traditional aircraft collaborative development, creating a new phase of aircraft collaborative development. With the development of digital technology and computer network technology, the role and status of DMU in collaborative development of the aircraft digital-ization is developing constantly. In this paper, the development process of the DMU is summarized according to the history of the aircraft digital cooperation .
