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: | Using finite element analysis software packages allows to reduce the design stage of a product. However, at present, due to the constant increase in engine parameters and as a consequence the increase in loads acting on components and parts, an important requirement is put forward for the quality and accuracy of calculation models. A contact interaction model is proposed that allows for the assessment of forced responses of bladed disks taking into account frictional damping in a linear formulation. This model has been verified. It is determined that using this model of contact interaction can significantly reduce time costs with comparable calculation accuracy. |
