Dynamic Vibration Absorber Having Coil Springs and Oil Damper for a Damped Vibration System
감쇠진동계에 부착된 코일스프링과 오일댐퍼로 구성된 동흡진기
Abstract
This paper presents the effectiveness of the dynamic vibration absorber consisting of a single mass, coil springs and oil damper on the resonance freauency ratio and amplitude ratio for damped linear systems, that is, primary vibration system with damping. The effects of the dynamic vibration absorber are investigated numerically and experimentally for values of mass ratio, natural frequency ratio, and damping ratio. The experimental results show good agreement with calculated ones. As a result, the characteristics shown by the present work are useful in optimal tuning the dynamic vibration absorber in practice.
