Abstract

Impact vibration absorbers have been used extensively to control vibrations of mechanical systems. This paper deals with an experimental study on the performance of bi-unit impact vibration absorbers. The objective of this research was to study the performance of staggered versus identical clearances for two impact balls. This means that in the staggered clearance, the two impact balls had different distances to travel before impacting the limit walls whereas the clearances were identical for the other case. An experimental setup was designed and constructed. A novel digital image system, consisting of high speed camera and image acquisition software, was designed. The primary system was tuned to have a natural frequency of 5 Hz. A time series data of the location of the impact wall and both balls was acquired through constant frequency and constant amplitude excitation. This data was used to obtain motion plots and frequency responses. It was demonstrated that the vibration absorber with staggered clearances was more effective than the vibration absorber with identical clearances.
