Abstract

The invention discloses a bundle wire and a method for constructing a three-dimensional design model thereof. The bundle wire includes a plurality of bundle wire cores, the bundle wire is covered with a covering, and has multi-level wire harness branches. The turning part; the construction method includes: selecting the construction form of the multi-core wire model, constructing the initial model of the multi-core bundle wire; solving the diameter information and physical property information of each branch wire harness according to the manufacturing process parameters of the bundle wire, and constructing the central axis of the bundle wire The space curve model of the beamline; based on the above information, the energy function model of the beamline is constructed, the initial model function of the space curve of the central axis of the beamline is solved, and the 3D design model of the beamline is constructed in the 3D space software based on the diameter information of the beamline. The invention aims to solve the problems of low authenticity of the three-dimensional design model of the wire harness and poor design quality caused by the fact that the manufacturing process of the wire harness and the actual physical properties of the wire harness are not considered in the traditional solution.

Description

technical field [0001] The invention relates to the field of building a three-dimensional model of an electrical grid, in particular to a cluster line and a method for building a three-dimensional design model thereof. Background technique [0002] With the development of aviation, aerospace, ships and other industries, not only the functional requirements are more and more powerful, but also the performance requirements are also greatly improved. The electrical grid system is a neural network of complex products, and the design quality of its wiring harness directly affects the electrical grid system. Installation quality and installation efficiency. In order to meet the transmission requirements of electrical signals and electric energy of many electrical equipment, and to facilitate the installation of wiring harnesses, the military aircraft uses 3D software to complete the design of wiring harnesses, and manufactures most of the cable parts in a clustered manner, and the...
