In order to improve the quality of riveting，the finite element analysis of the press riveting process under different riveting process parameter was carried out by using ABAQUS software from the perspective of analyzing the hole edge stress distribution and the riveting process parameter rules.The specific influnce rules of process parameters such as prefabricated hole chamfer， press-down amount， riveting speed，etc. on the hole edge stress were deeply explored.Through data analysis method such as equivalent contour and small characteristic function， the optimal combination of riveting process parameters was successfully determined and verified by tensile test. The results show that the optimal process parameters with a chamfer depth of 0.3 mm， a riveting speed of 15 mm/s， and a downward pressure of 3.2 mm can significantly reduce the hole edge stress distribution in around the connecting domain and improve the riveting quality.
