Advanced dynamic absorber design method for practical application

Abstract

A close investigation is made on dynamic absorber design using simplified vibration models. Dynamic absorbers have been widely used to reduce excessive vibration of engineering equipment at resonance frequencies. From the practical point of view, however, the conventional theory on the dynamic absorber design should carefully be applied because it is formulated under ideal assumptions. In this work, we point out errors that researchers may make when dynamic absorbers are designed in industry and suggest alternatives to conventional dynamic absorber design scheme.
