摘要: 针对飞机装配中外形曲面特征多、装配关系复杂、连接方式多样等带来的装配工艺设计问题,提出了一种基于非正交干涉矩阵的飞机部件装配序列规划方法.通过分析被装配零件的结构特点,增加非正交的装配坐标方向,构建了非正交干涉矩阵;给出了装配可行性的推导方法,实现了装配序列的自动生成.并以装配时间为目标函数,采用遗传算法对装配序列进行了优化.基于MATLAB仿真平台,对某型号飞机舱门装配过程进行了模拟.仿真结果表明,该方法简单易行.与传统的基于正交干涉矩阵的方法相比,对于可装配性和装配效率都有显著提高.

Abstract: Aircraft components assemblies contain many curved features in surface, complex relationships and multiple connects between parts, which make it difficult to design assembly process. A novel assembly sequence planning methodology based on non-orthogonal interference matrix was proposed. By analyzing the features of the part to be assembled, non-orthogonal assembly directs were extracted. The non-orthogonal interference matrixes were established. The method of deriving assembly feasibility was given to realize assembly sequence planning automatically. The sequences were optimized utilizing genetic algorithm, in which assembly time was used as the objective function. The assembly of the aircraft cabin door was simulated based on MATLAB platform. The simulation results indicate that the method implements simply. Assembling ability and efficiency are improved significantly compared to traditional method based on orthogonal interference matrix.
