摘要
飞机翼肋为机翼结构的核心承力部件。其加工精度直接影响机翼的气动性能与装配质量。针对翼肋因薄壁、复杂曲面及高长宽比特性导致的加工变形问题,结合某型铝合金翼肋的实际加工案例,从残余应力调控、加工仿真预测及装夹体系优化3个方面提出控制策略,并通过对比实验验证方法的有效性。结果表明,优化后翼肋平面度误差由0.30 mm降至0.08 mm,筋条间距合格率提高至95%,为同类零件加工提供了可复制的工程经验。
The aircraft wing ribs are the core load-bearing components of the wing structure.Their processing accuracy directly affects the aerodynamic performance and assembly quality of the wing.In response to the machining deformation problem caused by thin-walled,complex curved surfaces,and aspect ratio characteristics of wing ribs,combined with an actual machining case of a certain type of aluminum alloy wing rib,control strategies are proposed from three aspects:residual stress control,machining simulation prediction,and clamping system optimization.The effectiveness of the method is verified through comparative experiments.The results showed that the optimized wing rib flatness error decreased from 0.30 mm to 0.08 mm,and the qualified rate of rib spacing increased to 95%,providing replicable engineering experience for the processing of similar parts.
