Description
Summary:As a kind of interference rivet with compensation at the head, the reduced countersunk head half-crown rivet can achieve long life sealing riveting for airplane types or engine rooms with special requirements for sealing and fatigue performance. In the present study, a quartered three-dimensional finite element model was created to simulate the riveting process. The FE model was validated from the perspective of driven head dimensions and interferences based on the experiment results. The effects of feed displacement of rivet dies, feed speed ratio of rivet dies, pre-feed displacement of upper rivet die and countersunk depth on the forming quality of riveted lap joints were systematically studied. The results showed that the average interference increased with the increase of the feed displacement of rivet dies, while it decreased with the increase of the feed speed ratio of rivet dies and pre-feed displacement of upper rivet die. The countersunk depth of 1.05 mm is the transition depth for the rivet studied in this paper. In addition, the results of combined effect of feed speed ratio of rivet dies and pre-feed displacement of upper rivet die on the forming quality proved that the influence laws of single parameter were no longer suited for the scenario of combined effect of multiple riveting parameters. This paper can provide scientific and normative guidance for the applications of reduced countersunk head half-crown rivet in engineering structure.
