Multi-parameter joint optimization of self-piercing riveting on aluminum alloy plate

Self-piercing riveting technology can achieve more efficient connection of aluminum alloy plate parts. In this study, the 5052 plate and the 6061 plate are taken as the research objects. By establishing a finite element model and using a multi-objective optimization method, multiple parameters are jointly analyzed. The sensitivity parameter analysis was used to determine the value range of the research parameters, and the response surface analysis method was used to construct the functional relationship between the parameter variables and the system response. Finally, a multi-objective optimization model was established to obtain a reliable combination of rivet parameters and die parameters.
