Energy Harvesting from Vibrations of a Two-Degree-of-Freedom Mechanical System

In the paper, the energy harvesting from vibration of two-degree-of-freedom mechanical system is analyzed. The considered system consists of two mass linked in series by means of springs and dampers. The kinematic excitation of the system was assumed. The energy conversion system was placed in the suspension of lower mass. As a result of the analysis, the methods to increase the energy harvesting from vibration were proposed. The laboratory stand has been built and a series of measurements performed. Results of numerical simulations and measurements are presented in graphs.
