摘要

针对船舶中组立尺寸大、结构复杂、障碍物多，机器人自动化焊接难以应用，本文提出基于数据驱动的船舶中组立智能焊接技术，通过中组立三维模型和龙门式机器人构建仿真场景，采用广度搜索与深度搜索相结合的办法高效识别船体结构节点元素特征，并利用空间三维结构交线拟合提取焊缝曲线，建立安全焊接生产空间的防撞检测机制和避障规则，进而精准引导多机器人避障与自动焊接作业。结果表明，采用该智能焊接技术提高了中组立焊接效率和焊接质量，促进了船舶建造自动化、数字化生产，提升船舶行业智能化、先进工艺技术水平。

Abstract

This paper proposes a data-driven intelligent welding technology for ships unit assembly structure

which is difficult to apply due to the large assembly size

complex structure

and many obstacles in ships. The simulation scene is constructed through a 3D model of ship assembly and a gantry robot. The method of combining breadth search and depth search is used to efficiently identify the node element characteristics of the ship structure

and the weld curve is extracted by fitting the intersection line of the spatial 3D structure. A collision detection mechanism and obstacle avoidance rules for safe welding production space are established to accurately guide multi robot obstacle avoidance and automatic welding operations. The results indicate that the adoption of this intelligent welding technology has improved the efficiency and quality of intermediate assembly welding

promoted the automation and digital production of shipbuilding

and enhanced the intelligence and advanced process technology level of the shipbuilding industry.
