Eddy current oil film hybrid damper vibration damping performance of flywheel rotor system with single point flexible support
In response to the insufficient vibration damping performance of traditional swing oil dampers,an oil damper structure with a supporting spring as the elastic element was proposed,and a new eddy current oil film hybrid damper was designed by introducing eddy current damper on the basis of the oil damper.A flywheel spin test system was built to study the influence of different dampers on the amplitude-frequency characteristics and critical speed of the flywheel rotor system under different support stiffness,and the shaft centerline orbits and time-domain waveforms at different spin speeds were compared and analyzed.The results show that compared with oil dampers and eddy current dampers,the eddy current oil film hybrid damper performs the best in terms of vibration damping effect,with a maximum damping rate of 82.67％near the critical speed.The research results can provide technical support for vibration control of flywheel rotor systems with single point flexible support.
