Samara University Repository
Welcome to the Samara University repository!
This is an open electronic archive created to preserve and disseminate the scientific results of our university. The works of researchers, faculty members, and students are available to everyone for academic and research purposes.
The repository contains dissertations, research articles, educational and methodological materials, monographs, and regulatory documents. The collections cover a wide range of fields: from aerospace technologies, engine engineering, and computer science to history, linguistics, mathematics, and ecology. The archive brings together the scientific heritage of the university, including materials prepared during the period of Samara State Aerospace University and Samara State University.
Looking for publications by author, title, date, or subject? Full-text search will provide relevant results. Want to explore the academic life more closely? Browse materials by the universityâs organizational units.
Descriptions of all publications and articles available in the repository can be found in the libraryâs electronic catalog. Staff and students can log in via the menu "Login -> My Resource Archive" using their personal account credentials (SSAU_id).
Use the archive for study, research, and professional development!

| Abstract: | Squeeze film dampers (SFDs) are widely used in turbomachinery rotor supports to reduce vibration amplitudes, serving as a connecting element between the rotor and the housing. The structural simplicity of such dampers, including the studied model with an elastic ring, makes them promising for application in aircraft gas turbine engines (GTEs). The damper’s elastic element consists of a thin-walled ring with smooth bulges located on the inner and outer surfaces: the inner bulges are offset relative to the outer ones, creating conditions for combined energy dissipation—both through hydrodynamic forces and dry friction in the contact zones. |
