Outline of Final Research Achievements

The purpose of this research is to establish a technology for gas bearings that can be used under the operating conditions that operate continuously while changing the rotation frequency likes a rotary type vibration exciter.
Experiments were conducted to demonstrate that the rotor vibration reduction effect is always exhibited by controlling the gas supply pressure according to the rotation frequency. As a result, it was found that the rotor vibration reduction effect in the rotational frequency range changes when the frequency modulation cycle is fast and fast. In addition, the frequency response of the rotor bearing system was measured, and the characteristics at each frequency were clarified.
