Abstract

This experimental research deals with passive vibration control of a primary mass using an impact vibration absorber (IVA). This paper is on two types of IVAs, namely, a simple IVA and a compound IVA, which have different attachment configurations for the impacting mass. The main contribution of this work was to experimentally analyze the effect of attachment configuration on IVAs. Thus, the primary objective of this research was to compare the absorption characteristics of simple and compound IVAs in case of transient and forced vibration. The secondary objective was to determine the effect of system parameters on the absorption efficiency of a compound IVA for both transient and forced vibration. It was shown that, for forced vibrations, the simple IVA (compared to the compound IVA) has more pronounced inefficient absorption region. On the other hand, the compound IVA hardly has a clear inefficient absorption region. In the respective absorption region, it is noted that the simple IVA has a more prominent vibration absorption level. Practical applications of the results are also discussed.
