摘　　要：为了实现降低产品三维模型曲线的曲率极差的同时,达到提高工艺规程合格率、降低传递至执行端时长的目标,提出基于数字孪生的航空发动机工艺设计系统构建方法。利用基础数据层的数据库及文件系统调取基础数据层的航空发动机工艺数据,Savitzky-Golay滤波法对数据曲线作平滑处理后,Siemens NX软件构建航空发动机三维模型,实现航空发动机由物理环境到虚拟环境的数字孪生。设计结果经通信层的通信协议完成与用户层的数据交互。结果表明:该方法构建的工艺设计系统可实现航空发动机三维模型构建及曲线平滑处理,降低三维模型曲线的曲率极差和传递至执行端时长,提高工艺规程合格率。This paper presents a method of constructing aero-engine process design system based on digital twin is proposed,which can reduce the curvature range of product three-dimensional model curve,improve the qualification rate of process and reduce the transmission time to the execution end.The database and file system of the basic data layer are used to retrieve the aeroengine process data of the basic data layer.After the data curve is smoothed by savitzky Golay filtering method,Siemens NX software constructs the three-dimensional model of the aeroengine to realize the digital twin of the aeroengine from the physical environment to the virtual environment.The design result completes the data interaction with the user layer through the communication protocol of the communication layer.The results show that the process design system based on this method can realize the construction of aeroengine 3D model and curve smoothing,the curvature range of the 3D model curve and the transmission time to the execution end are reduced,and the qualification rate of the process procedure is improved.
