Reasonable interference fit riveting technology can effectively improve construction member′s fatigue behavior.In this paper,the effect of aperture size on very high cycle fatigue performance of interference-fit riveted part was investigated by the combination of experimental study with numerical simulation.By using 20 kHz ultrasonic fatigue experimental system,the very high cycle fatigue performance of interference fit riveted part with three different aperture sizes was tested.In addition,based on ABAQUS,...
