Realization of Flexible Attitude Adjustment Algorithm for Civil Aircraft Section Based on Engineering Constraints and Weight Optimization

民用飞机具有产品复杂、气动外形要求严格、产品构型众多、零部件数量巨大等特点,飞机制造过程中装配技术要求和工作量占比远高于其他一般的机械产品加工行业。调姿对接装配是装配工作的重要内容,高精度、低应力的对接装配是飞机成功制造和安全飞行的保证。基于奇异值解算与优化算法,根据民机装配工艺要求,在Python环境下开发并实现无权重与带权重的调姿解算算法,并通过比对现场数据解算结果的误差,验证算法的可靠性,从而开发面向不同飞机部段的装配工艺流程,向不同民机装配过程中调姿对接工艺定制化开发。

Based on the complexity of civil aircraft products,strict aerodynamic requirements for appearance,numerous product configurations,and huge number of parts,the proportion of assembly technical requirements and workload in the aircraft manufacturing process is much higher than that of other general mechanical product processing industries.Posture adjustment docking assembly is an important part of the assembly work.High-precision,low-stress docking assembly is the guarantee for the successful manufacturing and safe flight of the aircraft.Based on the singular value decomposition and optimization algorithm,the attitude adjustment solution interface is proposed and implemented,the weightless and weighted attitude adjustment algorithm is realized in the Python environment,the reliability of this algorithm is verified through the error comparison of the field data solution results.Therefore,for the assembly process of different aircraft sections,the corresponding attitude adjustment interface is customized for different process specifications through the algorithm.
