摘要：

为了实现压铆力作用下钉头成形过程材料流动及尺寸的分析，利用主应力法、广义变分不等原理、Avitzur上限法以及有限元等方法，分析了铆接成形过程材料流动特征下铆接力与钉头尺寸之间的关系。结果表明，在钉头不同压缩阶段几种理论分析方法与试验结果具有不同的接近程度，其中有限元分析的效果相对更好。由于理想镦粗模型与钉头成形在材料局部流动上的差异，几种经典分析理论在铆接钉头成形尺寸的精确研究方面还不足。考虑材料大变形过程中的塑性硬化及实际流动特征，对主应力分析法进行了修正，与试验结果对比表明，修正的主应力分析法极大地提高了铆接力-钉头尺寸关系的分析精度。

In order to realize the material flow and dimension analysis of nail head forming process under the action of pressure riveting force, the relation between pressure riveting force and nail head dimension under material flow characteristics during riveting process was analyzed by principal stress method, generalized variation inequality principle, Avitzur limit analysis, FEM and so on. The results show that several theoretical analysis methods have different close proximity to the experimental results in different compression stages of nail head, and the effect of finite element analysis is relatively better. Because of the differences in local material flow characteristics between ideal upsetting model and nail head forming, several classical analysis theories are insufficient in the precise study of the forming dimensions for riveting nail head. Taking into account the plastic hardening in the large deformation process and the actual flow characteristic of material, the principal stress method was revised. The comparison with the experiment results shows that the modified principal stress method greatly improves the analysis accuracy of the riveting force-nail head dimension relationship.
