The aim is to investigate the use of a Dynamic Vibration Absorber to control vibration in a beam. Traditional
means of vibration control have involved the use of passive and more recently, active methods. This study is different in that
it involves an adaptive component in the design of vibration absorber using a novel design of cantilever beam mechanism.
The design incorporates the use of two concentrated masses cantilevered from two rods. The adaptive solution is achieved by
moving the two masses along the length of the rod, producing a changing natural frequency for the absorber device. For this
the beam with Young’s modulus of 207*10^(9) Pa, density of 7800Kg/m^(3),width of beam (b)=0.025 m, height of beam
(h)=0.05m & length of beam (l)=1.135 m is used. This system is applied to a frequency range of 30 to 80Hz.
