APPLICATION OF THE ELECTROMAGNETIC DYNAMIC VIBRATION ABSORBERS TO SUPPRESS UNDESIRED VIBRATIONS AND HARVEST ENERGY

In this study. an electromagnetic energy harvester is considered to suppress undesired vibrations. For this reason. application of a dynamic vibration absorber system, which is equipped with an electromechanical device, is studied. In doing so, a theoretical model is developed to study the electromechanical behavior of the system. Then the results. which are obtained by solving the theoretical governing equation of motion and the Simscape toolbox in MATLAB software, are experimentally validated while the vibration absorber is tuned for the first frequency of the main system. Results show the dynamic vibration absorber can effectively Initigate undesired vibrations of the Inain vibratory system. Furthermore. it is shown that the average angular speed of the electromechanical generator is equal to 375 rpm, which can be increase in case of the system with higher natural fiequencies. Finally, it is shown that average of the harvested power by the presented system, which can be categorized as a small energy harvestingsystem. is equal to 0.l7W.
