Vibration study has become an integral part of system analysis these days. Most of the system failures occur due to excessive, unwanted vibrations. A Dynamic Vibration Absorber (DVA) is designed fabricated and tested for primary systems having single degree of freedom. The aim of the present study is to design DVA for two primary systems (laboratory models) i.e. Cantilever Beam and Vertical motion model (spring mass system) subjected to forced vibrations. Numerous papers published in international journals were studied and it was found that the research over DVA is not new and in fact there are a variety of practical situations in which DVAs are used. Innovative designs of DVAs which people have come up with were studied from the literature. While trying out various excitation mechanisms it was found that using cam was the best option. With the help of this project the students of our college can understand the concept of which DVAs work in practical situations and which may even inspire them to take up vibration control as their field of study.
