106 Vibration Control by a Passive Nonlinear Damper

Abstract

We generally use a damper and linear vibration absorber to prevent resonance. In this paper, we focus on resonance of forced vibration and parametrical resonance in mass spring system. We propose a nonlinear vibration absorber utilizing a nonlinear coupling so called internal resonance between mass spring system and absorber. We use a pendulum as a nonlinear vibration absorber. Theoretical results clarities the effect of the absorber for the resonances.
