Abstract：

In order to find out the quantitative laws of self-piercing riveting test indexes and joint strength, and the optimal combination of each factor level to make effective prediction, the self-piercing riveting tests for Al1060, Al5754 and Al6061 aluminum alloy thin plates were conducted by Box-Behnken Design (BBD) response surface method. Then, taking the hardness of upper plate, hardness of lower plate and length of rivets as the independent variables, and the failure load and energy absorption value as the response values, a multivariate nonlinear regression model for the strength prediction of self-piercing riveting joint was established. The test results show that the error of joint strength between predicted and test values is within 8%, which proves the reliability of the regression model. The variance analysis of the model shows that the hardnesses of upper and lower plates gave a positive correlation with the failure load of joint, and the length of rivet has a negative correlation with the failure load of joint. The interaction between the hardness of upper plate and the hardness of lower plate has a greater effect on the failure load and energy absorption of joint.
