摘要：With the rapid development of the aerospace industry, the demand for titanium alloy fasteners has been steadily increasing. For titanium alloy blind rivets, the bulge forming of heterogeneous thin-walled TA1 titanium alloy sleeves plays a critical role in joint quality. In this study, a numerical model of the heterogeneous thin-walled sleeve was established in ABAQUS, incorporating a hardness-based constitutive model. The stress-strain behavior of the material during the bulge forming process was analyzed, and the effects of protrusion length and inclination on bulge forming were investigated. Furthermore, the hardness distribution characteristics of the heterogeneous thin-walled rivet sleeve were examined using response surface methodology. The results indicate that the established numerical model of the heterogeneous thin-walled rivet sleeve agrees with experimental data within a 6% error margin. Pronounced stress concentration was observed on the concave side of the bulge, and the inner wall (A1) exhibited a fibrous grain structure with the highest degree of grain refinement. As the protrusion length increased, the bulge diameter showed an increasing trend, whereas the maximum compressive load and clamping force decreased significantly. Higher inclination angles exacerbated the plastic deformation on the inclined side of the bulge and led to a larger deviation in clamping force distribution. Significant interaction effects between protrusion length L and characteristic position yb on the bulge diameter and clamping force were observed; as L increased and yb decreased, the bulge diameter D increased nonlinearly, while the clamping force Fn decreased correspondingly. By performing a grid-based exploration of the L-yb combinations and screening feasible solutions, a reference framework was provided for dynamic matching of characteristic positions under different protrusion length conditions.
