Abstract

The invention relates to a method for constructing a three-dimensional model of an automobile wire harness based on the shortest path model; from the trunk to the branch, model layer by layer, follow the modeling method of the minimum space distance, compare the spatial distance of electrical components to determine the trunk of the wire harness; determine other electrical appliances branch; get the initial data model; determine the fixed point on the wire harness, use the intersection of the spherical surface and the wire harness model to get the fixed point area of ​​the wire harness, determine the positions of all the fixed points on the wire harness, and obtain the data model A; add the fixed point on the basis of the data model A Data model B is obtained by means of data model B; on the basis of data model B, the assembly margin design is added according to assembly requirements, and data model C is obtained; on the basis of data model C, external protection design is added according to actual needs, and the final data model of the wiring harness is obtained. The invention ensures that the wire harness model is the shortest path scheme, realizes the optimization of the layout scheme, improves the success rate and design quality of the first-time design of the wire harness model, and realizes the optimization of the wire harness cost from the wire harness layout path.

Description

technical field [0001] The invention belongs to the technical field of wire harnesses, and relates to a method for constructing a three-dimensional model of an automobile wire harness based on a shortest path model. Background technique [0002] The current 3D model design of automobile wiring harness is usually based on environmental data. The wiring harness layout path is not the shortest path. This design scheme will increase the cost of the wiring harness. At the same time, the wiring harness path has redundancy, which will not transmit signals to the vehicle. , power supply and vehicle EMC will also have a certain impact. A bad 3D model of the wiring harness will lead to inconvenient wiring harness assembly, the wiring harness cannot be well fixed in the vehicle environment, the safety distance between the wiring harness and the surrounding parts is too close, and even the reliability of the wiring harness is reduced. [0003] There are currently no similar implementat...
