A study on the dynamic vibration absorber with coil spring and oil damper was carried out both theoretically and experimentally. A main mass is was carried out both theoretically and experimentally. A main mass is attached to a foundation using coil spring and oil damper. A harmonic motion was applied to the foundation. Both the effects of the dynamic vibration absorber and BBN criteria for vibration specification are summarized in graphs, and tested on a vibratory model for the isolation of actual mechanical vibration.
As a result, we showed that the dynamic performance of designed oil damper in this thesis was improved in both low frequency and high frequency region.
