Abstract
In this paper the authors propose a dynamic absorber for a pole structure, as like a traffic signal pole on an express highway, in order to not only dissipate vibration energy, and also obtain an electrical energy. To investigate dynamic property, a test dynamic absorber that consist of rare-earth magnet, solenoid coil and spring was manufactured. An electric power and a damping force are measured by a shaking table. Also magnetic flux density around the solenoid coil with the magnets is analyzed by using FEM, and output voltage is calculated. Vibration tests of the test absorber are carried out and the experimental results are compared with the calculated results. The dynamic absorber is installed on a 1/3 scales pole structure model of, and investigate frequency responses by the test dynamic absorber.
