摘要
针对船舶外板喷涂机器人多层喷涂轨迹优化问题,以提高喷涂质量和效率为目标,提出一种平面多层喷涂轨迹优化方法。根据平面单层膜厚分布,推导建立平面多层漆膜分布模型,并采用快速非支配排序遗传算法(Non-dominated sorting genetic algorithm Ⅱ,NSGA-Ⅱ)优化各层喷涂轨迹。通过对船舶外板进行多层仿真喷涂,与未优化的喷涂轨迹比较,提高了漆膜均匀性和喷涂效率,验证了轨迹优化方法的合理性;与传统遗传算法优化对比,结果验证了NSGA-Ⅱ算法的有效性。
To solve the problem of optimizing multi-layer trajectory for ship outer plate painting robot, a planar multi-layer spray trajectory optimization method was proposed based on the purpose of improving painting quality and efficiency. The multi-layer paint thickness distribution model was deduced from the paint distribution for one layer on the planar, and the non-dominated sorting genetic algorithm Ⅱ （ NSGA - Ⅱ） was used to optimize the spraying trajectory. Compared with the un-optimized spraying trajectories, the coating uniformity and the spraying efficiency are improved by the multi-layer simulation spraying of the ship outer plate, and the rationality of the trajectory optimization method is verified. Compared with the traditional genetic algorithm, The effectiveness of NSGA - Ⅱ algorithm was proved.
