Course detail
FSI-RRSAcad. year: 2024/2025
In the course, students learn about the basic dynamic properties and dynamic behavior of components and parts of rotating systems. In particular, shafts, blades, and disks of turbines and compressors. Attention is focused on rotor natural frequencies, mode shapes, and critical speed prediction. Some problems can be computationally challenging, especially when solved in the time domain. Therefore, students will be introduced to methods of reducing degrees of freedom.

Entry knowledge
Students must be able to solve the eigen value problem, solve the response in forced, steady and transient oscillations of systems with n degrees of freedom. Furthermore, the students must to have knowledge of the basics of nonlinear vibrations, and knowledge of the basics of experimental modal analysis. The student must know, matrix calculus, linear algebra, differential equations, fundamentals of the finite element method.
Rules for evaluation and completion of the course
Active participation in the course, obtaining at least 20 points (out of 40 possible), which can be received by completing tasks and achieving at least 30 points (out of 60 possible) in the test. The specific form of the tests, types, number of tasks or questions and details of the assessment will be given by the lecturer during the semester. The final evaluation is given by the sum of the pointsaccording ECTS. For successful completion of the course it is necessary to obtain at least 50 points.
Aims
The course aims to introduce students to the basics of rotor-dynamic systems and evaluate the critical speed of shafts and disks.
Students will acquire basic theoretical knowledge in the field of rotor systems and reduction of degrees of freedom and will become familiar with the possibilities of computational modeling. They will learn how to predict resonance states and critical speeds of rotating machines and how to suppress them. Students will be able to perform a reduction of systems with many degrees of freedom, thus reducing computational time.
