3D simulation method and simulation system of complete electrical wiring harness

Abstract

The invention discloses a 3D simulation method and system of a wiring harness in a complete set of electric appliances. The method comprises the steps that a wiring diagram is traversed to obtain all components and wiring paths among the components; the wiring paths are traversed to obtain all effective path points; according to a Helen algorithm, the number of straight lead sections passing between every two adjacent effective path points is calculated, a wiring harness outer diameter database is queried, and cross section diameters of circles passing through two current effective path points are obtained; according to the extending directions of the straight lead sections passing between every two adjacent effective path points, the generating directions of the circles passing through the path points are confirmed; according to the cross section diameters of the circles of the passed effective path points and the circle generating directions, two-dimensional circular cross-section drawings corresponding to the points are generated; the areas of the two-dimensional circular cross-section drawings serve as path cross sections by adopting three-dimensional lofting, and a three-dimensional wiring harness is formed through lofting. A wiring diagram drawn in a line axis mode is displayed in a three-dimensional mode, and the production cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of complete electrical manufacturing, in particular to a 3D simulation method and a simulation system for a wire harness in a complete electrical set. Background technique [0002] SuperHarness is a secondary conductor CAD / CAM / CAPP software system used in the complete electrical appliance manufacturing industry. It uses the three-dimensional structural model of the cabinet and the wiring files generated by the Superworks electrical design software as the basic data to complete the three-dimensional wiring of the internal conductors of the electrical cabinet. Simulate, and then generate CNC codes for processing wires, complete the automatic manufacturing of wires; and generate nailboard drawings for wire harness manufacturing, complete the production of wire harnesses before the shell of the electrical cabinet is completed, and wait for the shell and components to be assembled. Install the wiring harness directly in th...

Problems solved by technology

[0003] In the existing SuperHarness software system, after the wiring is completed, the planar and spatial wire harnesses are displayed as a thin line, that is, displayed in the form of a spool. In this way, the three-dimensional effect and the specific display form of the wire harness cannot be vividly displayed to the user, which is difficult for the design work. bring great inconvenience
