ENERGY HARVESTER FOR VIBRATION CONTROL AND ELECTRICITY GENERATION

This paper presents the application of energy harvester for controlling the vibration of marine structures and also at the same time generates the electricity for charging the low power devices. The motivation behind this research is to remove the problem of electricity and at the same time controlling the vibrations of marine structures due to excitation. By using the MATLAB , the amplitudes of marine structure and energy harvester are calculated. A mathematical model was discussed briefly. The marine structure magnitude was calculated as 4.5 mm at the frequency of 10 Hz assuming that the mass of marine structure is 5 tons. After attaching the energy harvester, the marine structure amplitude become 1 mm. The remaining 3.5 mm amplitude was decreased by attaching the absorber. The generated a power of a energy harvester is 1.6?W.
