摘　　要：飞机装配自动制孔技术的应用,基本改善了制孔工艺任务繁重、零件制孔量大等问题。而在整体制孔效率方面,自动制孔设备需要一种高效的制孔路径规划方法。基于此背景,通过研究三维空间路径规划算法以及自动制孔技术,根据面向MBD三维信息模型制孔路径规划要求,将改进后的蚁群算法应用于飞机的三维空间自动制孔路径规划中,进行实验分析,实验结果表明:改进后的遗传算法在路径的最优解以及规划时间上都要优于计算机上用的枚举法。该算法的应用充分改善了制孔方式的无目的性、生成路径质量不高等不足之处,从而获得一条整体优化的路径,整体缩短飞机装配周期、提高制孔质量以及降低制造成本,推动和加速我国军民机的研制工作。The application of aircraft assembly automatic hole making technology,fundamentally improves the problem of aircraft integral in the development process of drilling technology of heavy task,parts of large amount of hole preparation. In the whole system efficiency,system of automatic hole equipment is in need of a highly efficient system of hole path planning method. Based on this background,it through the study of the 3-D path planning algorithm and automatic hole making technology,according to the MBD oriented 3D information model for pore path planning requirements,the three-dimensional space of the improved ant colony algorithm is applied to aircraft automatic hole making path planning,and the experimental results show that： the improved genetic algorithm to enumerate method is better than the computer used in path planning time optimal solution. The application of the algorithm fully improves hole preparation ways of nonobjective,the generated path quality not higher shortcomings,so as to obtain an overall optimization of path,shorten cycle,improve the whole aircraft assembly hole quality and reduce manufacturing cost,promote and accelerate the development of the work of military and civilian machine in China.
