Example Embodiment

[0030] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0031] Such as figure 1 As shown, the satellite structure design inspection method of the present invention is divided into three aspects, including:

[0032] Design compliance review, the compliance review refers to the review of the consistency of the design interface information in the process of multi-disciplinary collaborative design to ensure the accuracy of the design;

[0033] Model normative review, the model normative review refers to checking the modeling normativeness of th...

Abstract

The invention provides a satellite structure design inspection method and system based on a three-dimensional model, and the method comprises a design conformity inspection step: carrying out the inspection of the consistency of design interface information in a multi-professional collaborative design process; a model normativity review step: checking the modeling normativity of the design model;and a process inspection step: inspecting the process feasibility in the design process. The model checking state is managed according to the model version number, repeated checking is avoided, and the model checking efficiency and accuracy are improved; a designer carries out manufacturability review according to the process knowledge base rule, and iteration of design and the process is reduced;according to the method, special inspection software is customized and developed, related requirements in standard specifications are solidified into the software, the satellite structure model is inspected, the correctness and realizability of the design model are ensured, the design and manufacturing efficiency is improved, and the development period is shortened.

Description

technical field [0001] The invention relates to the field of aerospace vehicle structure products, in particular to a three-dimensional model-based satellite structure design inspection method and system. 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. High-quality, high-efficiency, and high-benefit satellite structure design is required. The existing satellite structure commissioning mode transmits information through a 3D model, which requires a more standardized and accurate 3D model of the satellite structure. Simplified 3D labeling of the existing 3D model of the structure brings difficulties to the model inspection and requires measurement on the model. This method is inefficient, poor in accuracy, and greatly influenced by human factors. In order to solve the abo...
