Effect of riveting parameters on the quality of riveted aircraft structures with slug rivet:

摘要

Slug rivet should be installed by automatic drilling and riveting machine due to its special structure. The investigation on slug rivet is limited. In order to promote the application of slug rivet, this article conducts investigations on slug rivet installation process. For the understanding of the riveting quality of a riveted lap joint, it is essential to analyze the riveting parameters. There are numerous parameters associated with a riveting process such as squeezing force, rivet structure, countersunk hole structure, hole diameter, sheet thickness, and clamping force. Incorrect selection or variations in these parameters could directly affect the riveting quality. The aim of this article is to study the impact of the aforementioned parameters on the riveting quality of a riveted aircraft structure. The interference condition is considered as the main quality control criterion. The squeezing force is introduced as the most important parameter for the riveting quality. The study provides a deeper unde...
