Abstract

Whilst the use of impact damper for single-degree-of-freedom (SDOF) systems has received a significant amount of attention, investigations into their interaction with SDOF systems is rare. In this paper, results of a series of experimental analysis of a horizontal PARTICLE IMPACT DAMPER under EARTHQUAKE and sinusoidally excited primary system are investigated. Specific impact damping is determined for a SDOF. The influence of some system parameters such as clearance, stiffness and specific intensity of excitation are investigated experimentally. Driven by the experimental observation, it has been shown that a value of damping capacity was reached with a PARTICLE IMPACT DAMPER. The obtained results proved the efficiency of this process for achieving high structural damping; the results in some instances did not correspond with those found for control of SDOF systems in particular.One of the main contributions of this investigation involves studying the sensitivity to stiffness. Increased stiffness of the vibration system did not necessarily lead to an increase in damping for all modes. Also, the effect of clearance is unpredictable. In short, the achievements gained in the paper have revealed dynamic characteristics, bringing important engineering application. The paper raises these and other issues which require consideration if impact dampers are to be used to control the dynamic response of SDOF systems.
