摘要: 针对薄壁异形无人机(Unmanned Aerial Vehicle,UAV)盖板在数控三轴加工中出现装夹困难、易变形和装夹效率低的问题,提出了一种基于有限元仿真的多工位工装-工艺协同优化与加工变形抑制方法,利用UG/NX软件进行有限元分析,识别盖板变形敏感区域,结合盖板切削参数优化工艺方案,设计模块化多工位工装。经实践证明,多工位工装-工艺协同优化后盖板变形得到抑制,每件换装时间缩短至9.5 min,生产效率提升了35.2 %;该方法已应用于中国兵器装备集团某型号无人机盖板批量生产,为薄壁异形件高效精密加工提供了理论支撑。

Abstract: Addressing fixturing challenges,deformation risks,and low clamping efficiency in 3-axis CNC machining of thin-walled complex-shaped Unmanned Aerial Vehicle (UAV) cover plates, an integrated multi-station fixture-process optimization and machining deformation suppression methodology leveraging finite element simulation was proposed. UG/NX-based Finite Element Analysis (FEA) identifies deformation-sensitive zones,enabling cutting parameter refinement and modular multi-station fixture design. Experimental results demonstrate effective distortion suppression,9.5 min changeover per workpiece,and 35.2 % productivity gain after multi-station fixture-process integrated optimization. Deployed in mass production of a China South Industries Group Corporation UAV model,this approach establishes a theoretical foundation for precision machining of thin-walled complex components.

Key words: integrated optimization, multi-station fixturing, machining distortion suppression, Finite Element Analysis (FEA), Unmanned Aerial Vehicle (UAV)
