摘要
以飞机大尺寸机身筒形结构件插接装配过程为对象,围绕插接部位不可见、不可测问题,基于数字孪生思想,提出了一种虚实结合、以虚控实的迭代递进式精准调装算法,搭建了包含飞机前机身、中机身比例实验件(以MA700前机身和中机身为参考)、六自由度并联调姿系统、手持式激光扫描仪、双目摄影测量系统、集成控制系统的实验教学平台,给出了“以虚控实”的实验流程。构建了大空间测量的实时感知、六自由度并联调姿和基于数字孪生的试装配仿真验证3个实验模块,不仅实现了智能装配、数字孪生等先进技术方法与飞机装配知识互补的理念,更锻炼了学生独立自主解决复杂工程问题的能力。
Based on the joining assembly process of the largescale cylinder structural parts of airplane,in order to solve the core problem of invisible and unmeasurable docking procedure,an iterative and progressive algorithm is proposed by combining data connection and interaction.An experimental platform is designed,including the front fuselage and the middle fuselage equal scale reduction text pieces(based on the front fuselage and the middle fuselage of MA700),the 6 degree of freedom parallel attitude adjustment system,the handheld laser scanner,the binocular measurement system and the integrated control system Experimental process of“controlling reality with virtual”is given.Furthermore,three experimental modules are constructed,namely,the realtime sensing of large space measurement,sixdegreeoffreedom parallel attitude adjustment and the assembly simulation based on digital twin,which not only realizes the concept of complementing the traditional knowledge of airplane assembly with the advanced technology like intelligent assembly and digital twin,but also exercises students’capability to solve complex engineering problems independently,and provides them with a platform environment for the integration of multidisciplinary knowledge system.It trains interdisciplinary compound talents.
