A 3D coordination method for aircraft products

Abstract

The invention belongs to the field of airplane design and relates to establishment of a method for conducting three-dimensional coordination on all systems of an airplane product in the detailed initial design stage. The method is characterized by comprising the steps that firstly, coordination of all specialties of the airplane product is divided into three types; secondly, three types of three-dimensional coordination models are established respectively; thirdly, mutual coordination is conducted between the specialties to confirm data. By means of the method, the whole course data transmission in the developing process of large industrial products such as airplanes is achieved, and thus the transmission of the coordination data is accurate and fast; the geometric models expressed with points, lines and planes which occupy quite little resources and quite small space are adopted in the three-dimensional coordination models to specially express the coordination information between the specialties, and the expressed content is concise and clear; the standardized three-dimensional coordination models enable coordination elements to be completely expressed, and missing and incompletion of the coordination elements are effectively avoided; the three-dimensional coordination models facilitate the concentrated expression of the coordination elements; state control is adopted in the three-dimensional coordination models, and thus data management and tracing are facilitated.

Description

technical field [0001] The invention belongs to the field of aircraft design, and relates to the creation of a method for three-dimensional coordination between various systems of aircraft products in the detailed preliminary design stage. Background technique [0002] For traditional aircraft, in the detailed preliminary design stage, the coordination between various disciplines uses two-dimensional coordination diagrams, coordination records and coordination minutes to record the coordination content between disciplines. The main basis for detailed design. Because aircraft products involve coordination among many disciplines, the content is very complex. An aircraft model often requires thousands or even tens of thousands of coordination sheets, and hundreds of large coordination maps need to be drawn at the same time. Drawing coordination diagrams and coordination records takes up a lot of time for designers, and the coordination workload is huge. According to statistic...

Problems solved by technology

[0003] In recent years, major aircraft research companies both at home and abroad have adopted electronic prototypes that establish three-dimensional solid models of parts to replace coordination diagrams, but the traditional two-dimensional method is still followed for the coordination record sheet that expresses the interface between disciplines.

This mixed coordination method of 2D and 3D interrupts the transmission of digital design data. In the process of converting 3D to 2D and 2D to 3D, problems such as data deviation and loss are likely to occur, and due to the large number of coordination records , drawing, printing and implementation all take up a lot of time for the designer
