Abstract

Fiber-reinforced polymer (FRP) reinforcement applied through surface bonding can significantly improve the mechanical performance and durability of steel structures. However, current FRP application largely depends on manual operations, making it difficult to precisely control process parameters and ensure optimal bonding quality. This study developed an automated robotic system for FRP application in steel structures, integrating steel surface grinding, adhesive application, FRP rolling/pressing, laying, and cutting. The research covers the mechanism design, control system development, and proposed a robotic reinforcement procedure. Parameter studies were conducted through experimental and theoretical analyses to determine the optimal sequence and operation parameters. Validation tests showed that under optimal parameters, the CFRP-steel interface achieved an ultimate load capacity of 46 kN, 32% higher than the manual result of 35 kN. Moreover, the robotic system applied single-layer FRP sheet 60% faster than manual operations. The development of an integrated end-to-end robotic FRP bonding workflow overcomes the limitations of manual methods and paves the way for intelligent construction technologies.

玻璃钢在钢结构中的应用自动化机器人系统

通过表面粘接进行纤维增强聚合物（FRP）加固，可以显著提高钢结构的力学性能和耐久性。然而，目前的FRP应用在很大程度上依赖于人工操作，难以精确控制工艺参数并确保最佳粘合质量。本研究开发了玻璃钢在钢结构中应用的自动化机器人系统，集钢表面磨削、粘合应用、玻璃钢轧制/压制、铺设和切割于一体。研究内容包括机构设计、控制系统开发，并提出了机器人加固程序。通过实验和理论分析进行了参数研究，确定了最优顺序和操作参数。验证试验表明，在最优参数下，cfrp -钢界面的极限承载能力为46 kN，比人工计算结果35 kN提高32%。此外，机器人系统应用单层玻璃钢板比人工操作快60%。集成的端到端机器人FRP粘合工作流程的发展克服了人工方法的局限性，为智能施工技术铺平了道路。
