摘　　要：针对目前航空结构件在进行生产加工过程中存在的问题影响,分析了研究航空结构件加工变形仿真关键技术的重要性,并提出了有限元模拟系统的构建方法和过程,其目的是为相关建设者提供一些理论依据。结果表明,仿真关键技术应用人员要想控制航空结构件加工变形问题,需通过体-壳单元应用技术、混合建模技术、单面约束问题和处理技术以及约束转换仿真技术入手,来减小毛坯初始残余应用的作用影响。Aiming at the influence of aerospace structure exists in the process of production and processing of the problems at present, this paper analyzes the machining deformation of aircraft structure key technology in the simulation of the importance, and proposed to build a system of finite element simulation method and process. Its purpose is to provide some theoretical basis for the builders. The results show that the personnel in key technology simulation in order to control the machining deformation of aircraft structure, through the solid shell element application technology, hybrid modeling technology, single constraint problem and processing technology and simulation technology of constraint conversion, to reduce the influence of low original residual application effect.
