| Research Abstract |
A vibration damper with plural vibrators which consist of a cantilever beam and a mass of its end has been developed to absorb the main system mechanical energy with their mutual collisions. Influence of a gap between the vibrators, the coefficient of restitution and the natural frequency on the damper performance is made clear in the case of two vibrators. It is shown that the effect for a three vibrators damper is same as the two vibrators. Vibration suppress for a structure with two directional vibrations in plane is tried by the vibrators moving in x-y plane and it is demonstrated that the present damper is also effective to the two directional vibrations.
