Aviation product digital twin geometric model quality control method based on door closure

Abstract

The invention discloses an aviation product digital twin geometric model quality management and control method based on door closing, and the method comprises the steps: setting one or more of a standard door closing, a grid door closing, an input door closing, an output door closing, a processing door closing, and a characteristic door closing in a product life cycle management system in advance; inputting part attribute parameters of the established aviation product digital twin geometric model into the product life cycle management system, and calling evaluation services of one or more doors; and calling a door closing conformity calculation service, and issuing a freezing technical state after the technical state auditing is completed. According to the method, the model quality inspection items are parameterized and preset in the quality gate closing rule through the threshold value parameter range, research and development problems caused by the model quality are judged in an aviation product digital twin geometric model design process in an auxiliary or automatic mode through the quality gate closing, the aviation product design iteration time is greatly shortened, and the research and development efficiency is improved.

Description

technical field [0001] The invention relates to the field of digital twin design of aviation products, in particular to a quality control method of a digital twin geometric model of aviation products based on a gate. Background technique [0002] Digital design has changed from 2D to full 3D expression. The development of aviation products adopts digital twin technology in an all-round way. The three-dimensional digital geometric model, as a common language throughout the entire product development, is the source of development. The current international method is to use full three-dimensional modeling technology. During the research and development process, problems such as multi-segment / slice discontinuity, multi-segment / slice overlap, garbage line / surface, line self-intersection, and surface normal jump will occur in the model, causing direct or indirect losses of hundreds of millions of dollars every year. [0003] The automatic inspection and optimization of digital mod...
