Abstract：

The riveting experiments of aluminum alloy 5052 sheets with 3 mm+3 mm thickness were carried out by hollow rivets and semi-hollow rivets with heights of 7 and 8 mm respectively, and the quality of joints was analyzed by analysis on the joint surface and joint cross section. Then, the tensile tests of riveting joints were carried out by universal testing machine, and the failure forms of joints were analyzed. The experimental results show that the quality of semi-hollow riveting joints is better than that of hollow riveting joints. With the increase of rivet height, the quality of both joints tends toward the same, and the strength of joints with semi-hollow rivets is higher than that of the joints with hollow rivets. When the rivet height increases from 7 mm to 8 mm, the riveting pieces of hollow rivets can withstand the maximum load from 85% to 87% of the riveting pieces of semi-hollow rivets and withstand the failure displacement from 50% to 80% of the riveting pieces of semi-hollow rivets.
