Mechanism Research on Target Accuracy of Aircraft Assembly Tooling Based on Multi-Factor Disturbance

针对飞机装配工艺装备的目标精度来源、影响因素等进行了详细分析,对目标精度的设计方法进行了描述,对其影响因素和重要程度分别进行了数据定量分析和定性分析,并针对不同影响因素给出了对应处理措施。对各项影响因素在应对措施下消除的可能性进行了个例研究和分析,从理论上对装配工装目标精度进行定量分析,并在某机型装配工装设计中进行了应用,初步为统一量化的装配工装工程精度分析探索了一条清晰路径。对目标精度的相关影响因素分析为飞机装配工装设计阶段的目标精度设计与预测、工装故障阶段的目标精度成因分析提供了参考。
