An Experimental Study on the Characteristics of Impact Vibration Absorber with Free Mass

Bo‐Suk Yang, Jongwan Kim

Open full text 0 citations

Abstract

In this paper, an impact vibration absorber that reduces the high vibration amplitude of a vibrating system is studied. This absorber consists of a free mass allowed to impact on to the secondary leaf spring so that the vibration energy is dissipated by converaion into noise and heat. The experimental parameters are weight of the free mass and impat clearance. According to the measured results, the high vibration in resonance region is reduced more effectively by the impact clearance ratio than by the mass ratio.
