The damping effects of an impact damper for the vibration neutralizer of pillar bodies are studied. The structure consisting of a beam, which is model of a pillar body, and an auxiliary mass coupled to the beam by means of a spring dashpot, which is a model of an impact damper, is considered. There is the gap between the beam and the auxiliary mass, and they collide with each other at one point when the system vibrates. The impact force is formulated by using Hertz's contact theory and the normal-mode approach is employed in the simulation. The validity of the simulation for free and random forced vibrations is examined by comparison with the experimental results. The effects of mass ratio, natural frequency ratio, gap size and impact point for free and random forced vibrations are discussed by simulation.
