摘要: In this study, we measured damping characteristics and frequency of magnetic fluid bearing spindles using a high-frequency vibration base by piezo actuator. Using the base, high excitation was added to mounted on proved that have effective damping. Also effect became larger with higher spindle rotational speed.
