基于数字化设计制造协同的飞机计量保障体系架构探讨

在国家科技创新,数字化设计制造高速发展的背景下,先进的数字化制造与传统的"先制造后检测再校准"的计量保障模式的矛盾愈发突出。以几何参数的数字化计量保障能力为例,通过分析对比国内外航空数字化设计制造工程中的几何参数计量保障工作现状,提出在飞机全生命周期内要保证产品数字化制造的几何尺寸精度,应依据新的产品几何规范,从产品的数字模型定义出发,面向数字化设计制造协同的关键过程和关键参数的测量溯源性要求,研究架构新的数字化计量保障技术体系,并就体系架构展开探讨。

Discussion on Aircraft Metrology Guarantee System Based on Digital Design and Manufacturing Collaboration

Under the background of national scientific and technological innovation and high-speed development of digital design and manufacture, the contradiction between advanced digital manufacturing and the traditional metrological assurance mode of "first manufacturing, then testing, and then calibrating for inspection" is increasingly prominent. In this paper, taking the digital metrology guarantee capacity of geometric parameter as an example, by analyzing and comparing the current situation of geometrical metrology guarantee status in aviation digital design and manufacturing projects at home and abroad, it is proposed that in order to ensure the geometric dimension accuracy of the digital manufacturing of products in the whole life cycle of aircraft, the new digital metrology guarantee system should be studied and discussed following the new product geometric specifications, starting from the definition of digital model of products and according to the measurement traceability requirements of key processes and key parameters for digital design and manufacturing collaboration.
