Problems solved by technology

[0003] 1) The design cycle is long, time-consuming and labor-intensive
[0004] The wiring technician responsible for producing the wiring diagram and wiring table can only passively accept the principle of the electrical system, and the two-dimensional wiring diagram is not intuitive, which is easy to cause omissions and high rework rate
In the traditional wiring production process, the wiring harness is generally laid according to the assembly situation of the whole machine entity and personal experience, and then in the wiring process, the unreasonable wiring is continuously corrected according to the process wiring principle, which is time-consuming and labor-intensive.
[0005] 2) The cable length cannot be accurately estimated
[0008] The two-dimensional wiring diagram can only describe the general direction of the cable, and the sense of space is not strong. When laying cables according to the two-dimensional diagram, it is often found that the cable direction interferes with the body structure
[0009] 4) The lashing is not aesthetically pleasing, often causing potential safety hazards due to unreasonable tying
[0010] These potential problems make the traditional electrical wiring design method become one of the bottleneck technologies affecting the design of the electrical system of the helicopter comprehensive test bench

Abstract

The invention provides a three-dimensional wiring design method of a helicopter comprehensive testbed and belongs to the field of helicopter comprehensive tests. The three-dimensional wiring design method is characterized by comprising the following steps of drawing a two-dimensional wiring diagram, defining electrical equipment numbers, electrical apparatus components, cable types and mutual wiring relations; modeling a mechanical structure; modeling and assembling electric parts and assembling the electrical parts and the mechanical structure model obtained in the step 2 according to constraint conditions; connecting the electrical parts obtained in the step 3 by virtue of three-dimension wiring; performing electromagnetic compatibility and spatial interference inspection on the helicopter comprehensive testbed subjected to three-dimensional wiring, and regulating wiring paths according to the inspection result. According to the method, three-dimensional wiring is adopted to simulate assembly sizes of objects, so that visual assembly during wiring of the helicopter comprehensive testbed can be realized, and the defects that the wiring path cannot be expressed by two-dimensional diagram and interference analysis cannot be performed on parts and wires can be overcome.

Description

technical field [0001] The invention belongs to the field of comprehensive testing of helicopters, relates to a three-dimensional wiring design scheme of a comprehensive testing platform for helicopters, and is particularly suitable for three-dimensional wiring of electrical systems in the development process of a comprehensive testing platform for helicopters. Background technique [0002] At present, the wiring harness diagrams commonly used in helicopter comprehensive tests are basically two-dimensional. The electrical system flow of traditional comprehensive test benches is as follows: figure 1 shown. This electrical wiring design method may lead to the following problems: [0003] 1) The design cycle is long, time-consuming and labor-intensive [0004] The wiring technician responsible for producing the wiring diagram and wiring table can only passively accept the principle of the electrical system, and the two-dimensional wiring diagram is not intuitive, which is eas...
