摘要
国外航空企业已经大量配备了自动钻铆系统,并广泛应用于飞机装配过程中。国内部分企业虽已经购买了自动钻铆设备,但是在应用过程中正在探索自动钻铆工艺参数优化、铆接过程微小变形控制等问题。本文从自动钻铆的工艺流程出发,分别从理论分析、有限元分析和试验分析3个角度,总结了自动钻铆过程中铆钉和薄壁件的应力应变分析方法,并对各种方法的优劣性进行了分析,最后以复合材料结构件铆接为背景,提出针对复合材料干涉铆接需要解决的关键问题。
Over the last years, automatic riveting systems are widely used in the aircraft assembly of the foreign aerospace industries. Chinese aerospace companies have purchased automatic riveting equipment, but there are several problems need to be solved, such as the parameter optimization and controlling of the small variation in the process of automatic riveting. Based on the process flow of the automatic riveting, the analysis methods of stress and strain in rivet and sheet metals are summarized respectively. Key problems for interference-fit riveting of composite material are also represented.
