摘　　要：我国现有飞机尾翼装配自动制孔方式为盲制孔,受飞机蒙皮和肋板自身形状结构限制,极易造成末端执行器制孔位置偏差。针对上述问题提出基于数字的飞机尾翼装配自动制孔系统框架,该系统框架包含物理层、数据层、连接层、虚拟模型层和服务层5个层次。构建数字孪生多领域多维模型,搭建基于统一架构的通信协议平台,利用虚拟模型进行仿真模拟,通过多种传感器实时监测系统运行状况,及时对各种数据信息进行处理并获取参数,对制孔加工参数进行迭代优化,实现自动制孔。The existing automatic drilling method of aircraft tail assembly is blind,which is restricted by the shape and structure of aircraft skin and rib plate itself,and it is very easy to cause the deviation of end-effector drilling position.In response to the above problems,this paper proposes a framework of digital-based automatic drilling system for aircraft tail assembly,which contains five layers:physical layer,data layer,connection layer,virtual model layer and service layer.The digital twin multi-dimensional model is constructed,an unified architecture-based communication protocol platform is built,the virtual model is used for simulation to provide a basis for the physical behavior,the system operation is monitored in real time by multiple sensors,various data information is processed in time to obtain parameters,and the hole-making processing parameters are iteratively optimized to realize automatic drilling.
