Aircraft wire harness automatic design method

Abstract

The invention provides an aircraft wire harness automatic design method, which comprises the steps of establishing an aircraft wire harness design top layer design specification, defining a design criterion and a constraint principle, and forming aircraft wire harness automatic design constraint parameters; in combination with the aircraft wire harness automatic design constraint parameters, customized top definition is performed on general Capital software, and aircraft wire harness automatic design project management parameters and design style parameters are set; carrying out topological interaction design on the aircraft topological graph and the aircraft line graph by utilizing Capal software and adopting existing aircraft topological design constraint parameters to generate a wiringharness model; and utilizing existing three-dimensional model design parameters, and combining with an airplane wire harness automatic design criterion and an airplane wire harness Capal library fileto carry out die repairing and parameter labeling on the wire harness model to form an airplane wire harness graph.

Description

technical field [0001] The invention relates to the design of aircraft wire harnesses, in particular to an automatic design method for aircraft wire harnesses based on Capital software. Background technique [0002] From the perspective of system engineering, aircraft wiring harness design is a work involving the coordination and cooperation of multiple disciplines. From the initial electrical system scheme design to further detailed electrical design, testing, analysis and verification, to pattern design and preparation of production documents, the entire system design process is relatively complicated and the workload is relatively large. With the development trend of more electric aircraft or all-electric aircraft, the electrical equipment on the aircraft has increased sharply, the electrical system has become more and more complex, and the model projects have higher and higher requirements for the development cycle, schedule, and funding. This development trend urgently...

Problems solved by technology

Our country started relatively late in the application of electrical wiring harness automation design. Although the theory and technology of each factory have accumulated to a certain extent, the overall level is uneven. The wiring harness design of some factories is affected by design ideas, software and hardware conditions, etc. Restricted by factors, there are disconnection problems at the level of 2D design and 3D design, design and simulation, which limits the improvement of design efficiency and quality
