|
Electromagnetic riveting is a new type of riveting process.In the process,the strain rate of metal material is high and the mode of the deformation of rivet material is different from that of conventional riveting methods.The purpose of the work is to analyze the factors which make an effect to the riveting quality,in particular,to analyze the relation between geometrical form of riveting die and the deformation of rivet tail and provide the theoretical references for optimizing design of riveting die.It is found that the angle of riveting die affects obviously shear stress and shear strain of rivet tail;And decreasing the angle can improve the distribution of the strain and prevent riveting cracks in rivet tail.Experiments indicate that the results of the numerical simulation are proper.
