摘要

This study examines a riveted joint of two plates, fabricated by the cold-setting method. The rivet, cooled in nitrogen, is inserted into a pre-drilled hole in the plates maintained at room temperature. A mathematical model of the setting process is developed. The model is used to determine the residual stresses and interference fit within the joint. The process is physically simulated, and the resulting joint is tested for tensile strength. Furthermore, the hardness is checked, and the surface of the rivet material is examined after the closing head is formed, including the fracture site from tensile testing. The results are compared with those for a plate joint formed by mechanical impact using a pneumatic tool. The analysis leads to the conclusion that cold setting ensures an interference fit in the plate joint without affecting the mechanical properties of the adjoining parts, thereby preserving the operational characteristics of the product.
