摘　　要：在航空航天产品中存在大量薄壁类零组件,零组件制造误差和零组件应力释放等会导致零组件在装配过程前出现变形。如果装配的所有零组件的尺寸或公差在极限尺寸下仍能实现互换,这往往对零组件要求太高,生产周期也过长,零组件制造成本也过高。针对产品零组件变形的不确定性,开展实测数据建模方法研究,将零组件几何模型、材料弹性参数、实物数据、虚拟装配和仿真分析等技术有效融合在一起,结合装配前零组件数据采集,对零组件变形体装配过程进行动态仿真分析,使得部分超差的零组件仍可进行正常装配。进而结合大数据、人工智能技术,给出现场变形体的装配性的等价模型及应用软件,实现基于生产现场零组件的实测数据可快速判定变形的零组件是否可装配,确保生产线可连续生产。There are a large number of thin-walled components in aerospace products,which deform before the assembly process due to manufacturing errors and components stress release.If all the dimensions or tolerances of the assembled components can still be interchanged within the limit size,it often requires too high requirements for the components,the production cycle is also too long,and the manufacturing cost of the components was also too high.In response to the uncertainty of product components deformation,the modeling method of measured data was conducted,which effectively integrated technologies such as components geometry,material elasticity,physical data,virtual assembly and simulation analysis.Combined with components data collection before assembly,dynamic simulation analysis was conducted on the assembly process of component deformation bodies.So that out of tolerance deformation components can still be assembled normally.Furthermore,by combining big data and artificial intelligence technology,an equivalent model and application software for the assemblability of onsite deformable bodies are provided,realizing the rapid determination of whether deformed components can be assembled based on measured data of components on the production site,ensuring the continuous production of the production line.
