Course detail
Rotordynamic Systems
FSI-RRSAcad. year: 2015/2016
The students are acquainted with the basic dynamic behaviour of rotor systems and construction of parts, shaft parts, non-linear coupling forces between rotating and non-rotating parts, turbine and compressor blades and disks. The subject focuses on theoretical, computational and experimental modelling. The natural frequencies and natural shapes of vibration, steady state and transient responses are analysed and discussed.
