A three-dimensional automatic design method and system for aircraft cables

Abstract

The invention discloses a three-dimensional automatic design method and system for an aircraft cable. The three-dimensional automatic design method comprises the following steps: performing an electrical design of the aircraft cable by using an E3.series tool to generate a simplified electrical report; calculating three-dimensional data of the aircraft cable, and encapsulating the calculated three-dimensional data into simplified and complete three-dimensional data files of an XML (Extensible Markup Language) format; automatically designing simplified and complete three-dimensional models of the aircraft cable by using a PRO / E tool; encapsulating the data file in the simplified or complete three-dimensional model into the XML format; and updating the electrical report into a complete electrical report by using the E3.series tool. Through adoption of the three-dimensional automatic design method and system, a three-dimensional automatic design of the aircraft cable based on the E3.series tool and the PRO / E tool can be realized. A method for extracting, calculating and converting three-dimensional data of the cable is provided. Generation of simplified and complete cable models is supported, and a cable length updating method is provided, so that digital three-dimensional assembly and production demands of the aircraft cable are met.

Description

technical field [0001] The invention relates to a design method for aircraft cables. More specifically, it relates to a three-dimensional automatic design method and system for aircraft cables. Background technique [0002] The cable on the aircraft is the carrier of information transmission on the aircraft, and is an important part of the aircraft, playing the role of the "neural network" of the aircraft. The design of the cables on the aircraft is mainly the design of two-dimensional electrical drawings and reports, and the three-dimensional design of the cables has not been realized. With the continuous improvement of the high integration and integrated design of the aircraft system, the information interaction relationship transmitted by the cables on the aircraft is becoming more and more complex, and the requirements for the design, production and assembly of the cables are getting higher and higher. 3D model design, accurate design of cable structure layout, intuiti...

Problems solved by technology

[0003] The problems encountered in the three-dimensional design of the cables on the aircraft are: 1) The cable on the aircraft is different from other equipment in that it is a flexible body with electrical and structural characteristics. At present, the three-dimensional design of the cables is done manually, which is inefficient. , the structural data of the cable is incomplete; 2) The 3D model of the cable is attached to the structural model of the cabin body, and the structural model of the cabin body is complex and has a large amount of information, which puts forward a lightweight requirement for the 3D model of the cable; 2) From the design of the cable and From the perspective of production, the 3D model information of the cable is required to be as comprehensive and complete as possible
