Japanese Patent JP2017089559

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a vibration-controlling power generator and a viaduct including it.SOLUTION: This invention comprises a base table installed on a structure to be controlled in vibration; a first additional mass body supported on the base table through a first elastic body in such a way that it may be vibrated vertically; a second additional mass body supported on the first additional mass body through a second elastic body in such a way that it may be vibrated vertically; and a linear power generator including a piston vibrated in a vertical direction through a relative motion caused by vertical vibration of the first additional mass body and the second additional mass body, a magnet fixed to the piston, a cylinder for movably storing the piston in its axial direction and a power generating coil arranged in the cylinder to enclose the magnet and has a feature that the cylinder is integrally formed with either one of the first additional mass body or the second additional mass body, supported in a vertical movable manner and the piston is connected to the other one of the second additional mass body or the first additional mass body and supported in a vertical vibratable manner.SELECTED DRAWING: Figure 5
