A study on the dynamic vibration absorber with coil spring and oil damper is carried out both theoretically and experimentally. A main mass is connected to a foundation through three coil spring and an oil damper. A harmonic motion is applied to the foundation. The effects of the dynamic vibration absorber on the acceleration amplitude ratio are theoretically summarized in graphs, and tested on a vibratory model.
As a result, the first resonance acceleration amplitude ratio is decreased and the second resonance acceleration amplitude ration is increased as the absorber mass increase. When the absorber spring constant increase, the first resonance acceleration amplitude ration is increased and the second resonance acceleration amplitude ration is decreased.
