Abstract

The invention discloses a bundled wire and a three-dimensional design model construction method thereof. The bundled wire comprises a plurality of bundled wire cores, a coating is arranged outside thebundled wire, the bundled wire is provided with multiple stages of wire harness branches, and the bifurcation point of the central axis of each branch is also provided with an inflection part. The construction method comprises the following steps: selecting a construction form of a multi-core wire model, and constructing an initial model of the multi-core bundled wire; solving the diameter information and the physical attribute information of each branch wire harness according to the manufacturing process parameters of the bundled wire, and constructing a space curve model of the central axisof the bundled wire; and constructing an energy function model of the bundled wire based on the information, solving a space curve initial model function of the central axis of the bundled wire, andconstructing a three-dimensional design model of the bundled wire in three-dimensional space software based on the diameter information of the bundled wire. The objective of the invention is to solvethe problems of low trueness and poor design quality of a wire harness three-dimensional design model due to the fact that a wire harness manufacturing process and actual physical attributes of a wireharness are not considered in a traditional scheme.

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...
