    Using rotor kit Bently Nevada for experiments with aerostatic bearings

  • Original language description

    Superstructure of Rotor Kit Bently Nevada was designed for identification of aerostatic journal bearing dynamic properties. The test stand enables to run the test shaft up to 10 000 rpm and to excite test bearing by forces with frequency from 0,1 Hz to about 100 Hz. Up to now measured results show reasonable agreement with calculation as concerns quasi-static stiffness and direct elements of stiffness matrix. The agreement between theory and experiment of main elements of damping matrix is somewhat worse and cross-coupling elements of stiffness and damping have considerable scatter. More sophisticated methods of dynamic coefficients idenification are elaborated to improve credibility of results.

    Dynamické experimenty s aerostatickými ložisky na rotorovém stendu Bently Nevada

  • Czech description

    Byla navržena a zkonstruována nadstavba rotorového stendu Bently Nevada pro identifikaci dynamických vlastností aerostatických ložisek. Maximální otáčky rotoru jsou 10000 ot/min a budící frekvence od 0,1 Hz do 100 Hz. Dosavadní výsledky vykazují shodu identifikovaných veličin matice tuhosti a v hlavních prvcích i matice tlumení. Nediagonální prvky matice tlumení nejsou dosud dostatečně reprodukovatelné a jsou ovlivněny chybami experimentů. Proto jsou navrženy úpravy experimentu i vyhodnocení tak, aby poskytly robustnější výsledky.
