Abstract

The invention relates to a cellular board precision design control and detection method based on a three-dimensional model in the technical field of aerospace craft supporting structure modeling design and detection, and the method comprises the following steps: S1, building a cellular board model: building a cellular board three-dimensional model, and setting the cellular board design precision;S2, cellular board real object measurement: measuring a cellular board by adopting digital measurement equipment, establishing a measurement coordinate system, and obtaining a cellular board characteristic measurement value; S3, matching and evaluating measurement data: importing the measurement data into the design model through a measurement software system, matching the design value and the measurement value of the cellular board, and carrying out conformance evaluation; and S4, outputting a detection report: outputting the detection report according to the acceptance template. Precision design control of the cellular board three-dimensional model is achieved, all related links of the 3D technology in the whole process of design, technology and detection are broken through, the cellularboard product quality is improved, the cost is reduced, and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of modeling design and detection of aerospace vehicle support structures, in particular to a method for precision design control and detection of honeycomb panels based on a three-dimensional model. Background technique [0002] At present, the development of satellites is faced with the situation of simultaneous development of multiple models, high-density launches, high quality and reliability requirements, and short development cycle requirements. Honeycomb panels are widely used in satellites due to their outstanding advantages such as simple structure, high specific stiffness, high specific strength, good bending stiffness and fatigue resistance. As an important part of the main structure and the basic structure of large accessories, the honeycomb panel plays the role of providing support, bearing and transmitting loads. [0003] Existing precision design and detection of honeycomb panels are based on ...
