摘　　要：现阶段,随着飞机制造装配过程的自动化建设要求,对飞机各部件的装配精度、方法、空间占用率、控制方式以及人身安全等提出了更高的要求。其中,由于装配工作需要,飞机大部件的自动变位成为亟待解决的问题之一。传统的飞机大部件变位方式与机构存在使用效率低下、占用空间大、操作困难及安全隐患等问题,已无法满足现代航空制造业的生产要求,急需改进创新。以机翼部件整体自动变位要求作为研究内容,分析机翼部件自身结构特点及变位要求,结合曲柄滑块机构原理,设计出新型自动变位机构以及运动控制系统。同时,基于有限元分析方法,使用MSC.Patran&Nastran工程软件对自动变位系统中主要受载结构进行刚强度校核,以满足机翼部件整体安全可靠的自动化变位要求。Nowadays,for the requirement of developing automation in the process of aircraft manufacturing,higher requirements are placed on the assembly accuracy,methods,space occupancy,control mode and personal safety of the various components of the aircraft.Due to the assembly work,it has become one of the vital problems to be solved that large parts of the aircraft can’t change their position automatically.Traditional position-changing modes have problems such as inefficient use,large space occupation,operational difficulties and safety hazards,which make it impossible to meet the production requirements of modern aviation manufacturing industry,so there is an urgent need for improvement and innovation.In this paper,requirements of the automatic position-changing of the wing parts are taken as the research content.First,the structural characteristics and position-changing requirements of the wing parts are analyzed.Then,combined with the principle of the crank slider mechanism,a new automatic position-changing system and control system are designed.At last,based on the finite element analysis method,the MSC.Patran&Nastran engineering software is used to perform the strength calculation on the main load-bearing structure to meet the demand of the secure and reliable automatic position-changing of the wing parts.
