Abstract: |
In this paper, we designed a kind of SWATH-USV through corresponding ship hull parameters selected as design variables to identify the SWATH performance as Optimal objective function and constraints for rapidity and maneuverability of SWATH. Via a multidisciplinary optimization design and analysis software, we analyzed and compared the single optimization of rapidity and the comprehensive optimization of rapidity and maneuverability. By comparing the fitness function values of the chaos algorithm and the hybrid algorithms of discrete genetic iterations, it was found that the genetic algorithm of 5000 generations combined with comprehensive optimization of rapidity and maneuverability has the highest value, and the optimal optimization results of ship form parameters were generated. |
