Analysis of the principle of exciting the turbine wheel of the magnet in various modes
Voronova, Evgeniya ; Maturkanič, Dušan ; Procházka, Pavel ; Hodboď, Robert
The report analyzes the principle of excitation of turbine wheel vibration by means of magnets switched on in harmonics, pulse, pulse-synchronous on IRC (encoder) and pulse-synchronous on IRC (encoder) and strain gauge. Furthermore, the effect of the pulse width and axial magnet excitation frequency on the turbine wheel model blade vibrations was verified.\n
Analysis of the turbine wheel model vibration
Voronova, Evgeniya ; Maturkanič, Dušan ; Procházka, Pavel ; Hodboď, Robert ; Košina, Jan
The paper describes the verification tests which were performed for 2000 rpm. Determined effects of vacuum on wheel vibration at 100 rpm and at \n500 rpm. Compare measurements at different speeds, with free oscillation or forced oscillation.\n
