Abstract

One of the operations during the airframe assembly is the installation of temporary fastening elements. Temporary fasteners are installed to join the assembled parts and prevent the gap opening while drilling and reaming. If the diameter of temporary fastener is less than the diameter of predrilled hole, the relative tangential displacement of assembled parts can occur during the temporary assembly process. The correct simulation of this phenomenon requires the account for friction in fastening elements while solving the contact problem in order to find the displacements of joined parts. Such numerical approach is presented and discussed in the paper.
