Abstract
The invention provides an intelligent wiring harness design method. The method comprises the following steps: establishing a platform database; calling a connector digital model and an accessory digital model in the 3D database, and connecting the connector digital model and the wire harness digital model by using the wire harness digital model; checking the bending radius in the wire harness 3D graph, and checking the wire harness arrangement direction in the wire harness 3D graph; obtaining the drawn electrical schematic diagram, and filling the wire data information in the electrical schematic diagram into the wire harness in the wire harness 3D diagram; automatically calculating the outer diameter of the wire harness in the wire harness 3D diagram through computer programming to complete the wire harness 3D diagram; generating a wire harness 2D graph according to a wire harness flattening method; checking and updating the 2D image of the wire harness; and carrying out sample line trial production and loading verification according to the wiring harness 2D drawing, and freezing the drawing. According to the intelligent wire harness design method and device provided by the invention, the workload is effectively reduced, the error rate is greatly reduced, the functions of platform database management, automatic information interaction and automatic error correction are provided, and the information of a wire harness 3D graph, a wire harness 2D graph and an electrical schematic diagram is unified.
Description
technical field [0001] The invention relates to the technical field of electrical design of automobiles, in particular to an intelligent wiring harness design method and device. Background technique [0002] With the rapid development of electronic and electrical systems in modern automobiles, buses, and aircraft, there are more and more electrical equipment, and the amount of information processing is increasing, even reaching tens of thousands. The workload increases accordingly, and the error rate rises rapidly. Traditional The design method has been unable to meet the needs of wire harness design, mainly reflected in the following points: [0003] 1. Traditional wiring harness design has no platform concept, no centralized database management, increased repetitive work, and no continuity of design accumulation. [0004] 2. The traditional wiring harness design uses purely manual methods for calculation, proofreading and processing information, with heavy workload, long ...
