摘要：
As fasteners with excellent performance, swage-locking pins have been widely used in aerospace, rail transit, bridges and building structures. To study the mechanical properties of domestic high strength stainless steel short tail swage-locking pins, uniaxial tensile tests, preload measurement tests, tensile and shear bearing capacity tests and riveting sequence tests were carried out on M20 swage-locking pins. The results show that the material of the swage-locking pins, that is, the precipitation hardening stainless steel 05Cr17Ni4Cu4Nb, has a high strength and good ductility. The heat treatment process can significantly improve its strength. The average value of the preload measurement results of swage-locking pins was 205.6 kN. It is recommended to use 155 kN as the design value of the preload of the M20 high strength stainless steel short tail swage-locking pins. The relaxation of the preload is negligible. The riveting sequence of the group of swage-locking pins is arranged from the center to the edge, and from the part where the joint rigidity is large to the part where the constraint is small.
