摘要
为了提高装配质量和寿命,自动钻铆技术在飞机装配中得到广泛应用,而钻铆参数是影响装配效率和质量的关键因素。文章通过有限元模拟技术对无头铆钉铆接变形进行了分析,提炼了自动钻铆工艺参数,并结合G86自动钻铆系统,采用正交试验法进行了无头铆钉的工艺试验研究,通过极差分析法确定了无头铆钉的钻铆参数值,为无头铆钉在飞机装配中的应用提供了依据。
The automatic drilling and riveting technology is widely used to improve in the aircraft assembly industry, and the drilling and riveting parameters are the assembly quality and service life key factors which affect the effi- ciency and quality of assembly. Sections 1 through 4 of the full paper explain our semi-empirical research men- tioned in the title, which we believe provides some theoretical basis for P. R. C. aircraft assembly engineers. Their core consists of ： （ 1 ） the deformation of headless rivet was analyzed using finite element method ; （2） the process parameters of the automatic drilling and riveting were distilled; （3） an orthogonal experimental method with range analysis was used on the riveting of headless rivets to find the reliable parameter values. Based on the experiments and theoretical analysis in sections 1 through 4, section 5 presents three preliminary conclusions which provide some theoretical basis for the headless rivet application in P. R. C aircraft assembly.
