飞行产品对装配精度有着较高要求,飞机制造或者装配出现误差将使各种不确定风险增多,影响到装配准确度。容差与工艺余量是零部件制造误差与补偿产品装配积累误差的重要衡量标准与参数,主要采用微分数学理论与计算机仿真模拟实现无余量装配容差分析的技术应用,应用此技术可减少误差,从而减少出现返工、修配等问题,节省了资源与制造成本。将基于飞机机翼装配,对支持无余量装配的容差分析技术进行研究,以提高飞机制造精准度。
Flight products have high requirements on the assembly accuracy, aircraft manufacturing or assembly errors will make a variety of uncertainties increase, affecting the assembly accuracy. Tolerances and allowances are important measurement standards and parameters for component manufacturing errors and errors in assembly product error compensation. The application of tolerance-free assembly tolerance analysis is mainly based on differential mathematical theory and computer simulation, and the application of this technique can reduce errors , Thereby reducing the rework, repair and other issues, saving resources and manufacturing costs. Based on aircraft wing assembly, tolerance analysis techniques supporting no-margin assembly will be studied to improve aircraft manufacturing accuracy.
