The invention belongs to the field of CAE (
Computer Aided Engineering)
engineering simulation and the technical field of electrical
interconnection system engineering, and particularly relates to a CATIA (
Computer Aided Three-dimensional Interactive Application)-based wire harness whole-process
motion simulation method, which comprises the following steps of: 1) constructing a motion mechanism
simulation model; 2) defining main attributes influencing the movement of the wire harness; 3) establishing a wire harness
simulation model; 4) based on the wire harness simulation model, simulating the wire harness on the movement mechanism, updating the wire harness simulation model in real time, and meanwhile, selecting an extreme state section for conformity analysis in each time form of a movement wire harness section; and 5) if the conformity analysis is passed, outputting the picture containing the wire harness simulation model at each moment, regenerating the screenshot under the fixed
visual angle into a video through video synthesis
software, and if the conformity analysis is not passed, returning to the step 2). The method is suitable for complex movement, and analysis results of the length, the shape, the bending degree, the stretching, the
stress concentration point and the like of the wire harness in the movement process can be more visually output.
