DESIGN AND DEVELOPMENT METHODOLOGY OF ADAPTIVE VIBRATION ABSORBER

The aim of this project is to how to reduce vibration through dual cantilever mass mechanism which is call adaptive vibration absorber that is different than the tune vibration absorber. 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. To do so we applied this system to frequency range of 30 to 80 Hz .For our design we take concentrated masses of 1.2 kg. When we change length from 81.5mm to 210 mm. So, our frequency range will be in range of 80 to 30 Hz (natural frequency).We would design the absorber for the setup having maximum acceleration at 50 Hz frequency and observe the amount of vibrations absorbed by it.
