Abstract:

：For the cable harness wiring difficult problem of complex mechatronic products, a three dimensional space-wiring technology for cable harness based on multi-scale chaotic mutation particle swarm optimization algorithm is proposed. Firstly, the influence of cable harness wiring sequence on connecting result is analyzed, and the algorithm solve space is defined by abstract modeling of three dimensional wiring space environment. To realize the local solution escape of path optimization, the idea of chaotic mutation is introduced in the particle swarm optimization algorithm. To solve the problem of single mutation scale does not guarantee to obtain the optimal solution, and improve the overall and precise local optimization algorithm performance, the competitive mechanism among different mutation scales is used to make the whole population to search the solution space distributed. Finally, four kinds of standard Benchmark testing functions are chosen to test the proposed algorithm, and the proposed method is validated by using the algorithm in the process of cable harness wiring for a certain phased array radar.
