航空发动机总装脉动线单模块集成仿真分析

航空发动机总装脉动线具有主体设备技术复杂、建设和运维成本高等特点,单工位模块是总装脉动线的基本组成单元,承担着航发产品总装时的脉动运输、夹持固定、部件对接和配套件安装等任务,因此在工艺流程规划、设备运动控制等方面存在较大难度,脉动线单模块的集成仿真可以验证单模块结构与机构设计、工作流程设计和运动控制设计方案,对于模块开发具有重要意义。提出基于数字孪生模型和实际控制信号的人在回路的单模块集成仿真方案,并据此研发了完全知识产权的国产仿真软件和集成仿真平台,完成了某型航发脉动总装工艺的评估。结果表明,所研发平台能够用于多种脉动总装工艺评估,并可支持人在回路的方案验证和操作培训。

Typical Module Integrated Simulation for Aero-Engine Pulse Final Assembly Line

The aero-engine pulse final assembly line(PFAL)has the characteristics of complex main equipment,high construction and operation cost.The single station module is the basic unit of PFAL,which undertakes the tasks of pulsating transportation,clamping and fixing,large parts docking and parts installation,therefore,it is difficult to plan the process flow and design the equipment motion program.The integrated simulation of PFAL can verify the structure and mechanism design,workflow design and motion control design of single-module,which is of great significance for typical module development.In this paper,a typical module integrated simulation with man-in-loop scheme based on digital twin model and actual control signal is proposed.Based on this scheme,the domestic simulation software and integrated simulation platform with complete intellectual property rights are developed,and the evaluation of a certain type of aircraft generator pulse assembly process is completed.The results show that the developed platform can be used to evaluate the new pulsation assembly process of aero-engine,and can support the scheme validation and operation training of man-in-the loop.
