331 Prevention Method Using Dynamic Absorbers for Pattern Formation Phenomena : Experimental Verification to Viscoelastic Multi-degree-of-freedom System

Abstract

The major occurrence mechanism of pattern formation phenomena has been considered as unstable vibrations generated in linear time delay systems. A stabilization of a multi-degree-of-freedom system using dynamic absorbers was proposed as one of prevention methods, and the validity was confirmed from numerical analysis. In this report, an experimental setup of a viscoelastic system was fabricated in order to verify the validity of dynamic absorbers. The experimental results indicate that the prevention method using dynamic absorbers is effective for the pattern formation phenomena in multi-degree-of-freedom system.
