摘要: 提出了一种基于空间扫略的飞机产品装配路径规划方法来解决飞机装配路径规划难题.首先,在装配顺序的基础上,综合考虑装配过程中装配型架、夹具、工具的作用,提出了整个装配路径规划流程;其次,基于装配顺序并充分考虑装配资源的角色作用,建立了面向路径规划的向导模型;然后,针对飞机装配特点,构建了相关路径障碍空间、空间扫略闭包及装配路径闭包,根据空间扫略算法生成了相关零部件在相应装配向导模型约束下的装配路径;最后,对生成的装配路径进行了参数化定义与分析,通过对装配干涉阈值的定义和优化调整,完成对装配路径的优化.在理论研究的基础上以某型飞机前缘襟翼架上装配为实例,针对其9号蒙皮装配进行路径规划与优化,验证了方法的可行性与有效性.

Abstract: In order to get effective assembly path, a space swept algorithm based assembly path planning method to plan the assembly path of aircraft was presented. Firstly, by considering the rules of assembly fixtures and tools in aircraft assembly process, the whole process of assembly path planning for aircraft was formed on base of the assembly sequence. Secondly, the guide model of path planning was developed on the base of assembly sequence which was integrated with the assembly resources. Thirdly, the path obstacle space, space swept closure as well as the assembly path closure were defined, and the path was formed according to the space swept algorithm which can form a sweptvolume between the part and its kinetic orientation. Lastly, the parameters of assembly path were studied, and the assembly path was also optimized according to the threshold adjustment of interference. On base of the theoretical analysis, a case of the assembly of a fore flap was studied to prove this method can solve a practical application quit efficiently.
