Mechanical vibration damper for conversion of mechanical vibrations into electrical energy has mass connected to piezoelectric element connected to control circuit

摘要

The damping system has a heavy mass (5) fastened to one side of a baseplate. A piezoelectric element (3) and a control circuit (4) are fastened to the other side. A spring (2) connects a vibrating mass (1) to the piezoelectric element. The motion of the mass (Delta x) produces a varying force (Delta F) on the piezoelectric element, which produces a varying electrical voltage (Delta Q).
