Abstract:摇In order to study the influence of the number and distance of rivets on the performance of self鄄piercing
riveted joints, the numerical simulation and experiments were conducted to optimize the parameters of self鄄piercing
riveting (SPR), and three different types of joints were made. The static performance and failure modes of different
joints were studied based on the tensile鄄shear tests. And the energy absorption value was calculated accurately though
the user defined development which is based on MATLAB R2014b platform. The results show that the numerical sim鄄
ulation result was highly identical to the experimental result. The single鄄riveted joints failed by the rivet being pulled
out from the lower sheet, and the double鄄riveted joints failed due to the sheet fracture. The performance of double鄄riv鄄
eted joints was obviously superior to that of single鄄riveted joints. However, the distance of rivets had little influence on
the static failure strength and energy absorption performance.
