AI Technical Summary

Technical Problem

Existing technologies cannot effectively utilize historical aircraft shear sheet models and data in the design of new aircraft, resulting in low design quality and low efficiency, requiring designers to make extensive manual interventions.

Method used

A knowledge base for cutaway slices is constructed by acquiring a 3D model library and a text information library to generate a structure tree, a function tree, and a constraint tree. These are then organized into a knowledge graph for knowledge fusion and reasoning, eliminating redundancy and errors, and supplementing unknown knowledge.

Benefits of technology

It achieves high-precision consistency in the design of shearing blades for newly developed aircraft, supports large-scale customized automated design, and improves design quality and efficiency.

Abstract

The present disclosure relates to a method and system for constructing a knowledge base of a cut sheet. The method comprises: obtaining a three-dimensional model library and a text information library of the cut sheet; extracting the cut sheet from the three-dimensional model library and the text information library, and decomposing each cut sheet based on structure, function and constraint relationship, thereby generating a structure tree, a function tree and a constraint tree; analyzing the decomposed cut sheet, and generating a structure-structure relationship tree, a function-structure relationship tree and a constraint-structure relationship tree; and arranging all the structure tree, the function tree, the constraint tree, the structure-structure relationship tree, the function-structure relationship tree and the constraint-structure relationship tree to generate a knowledge graph. The present disclosure mines historical cut sheet models and related text information accumulated in the aircraft development process, constructs a high-consistency and high-precision cut sheet knowledge base for the cut sheet design of a newly developed aircraft, supports automatic design of a large number of customized cut sheets for the newly developed aircraft, and improves design quality and design efficiency.
