Vibration cylindrical shells containing flowing fluid
Zolotarev, Igor
The natural frequencies of the free vibration of a circular cylindrical shell containing flowing inviscid fluid are studied. The numerical results obtained by use ANSYS numerical package are analyzed for frequency-modal properties of two different numerical models and compared with results of the analytical calculations. Application different FEM models that are created with using fluid-structure-interaction elements (FSI) and without it are analyzed too.
Design of aerodynamic Tilting-pad journal bearings and corresponding dynamical experiments
Šimek, J. ; Kozánek, Jan ; Šafr, M.
In this paper the design of aerodynamic tilting-pad journal bearings is presented and corresponding dynamical experiments are proposed. The experimental test stand with HF electric motor will be built at Institute of Thermomechanics, Czech Academy of Sciences, Prague. The rotor and pad vibrations will be measured. The vibrational data analysis will enable spectral and moda lidentification of this rotor-bearings system.
