OSCILLATING SYSTEM LINKED WITH A DEVICE SUBJECTED TO EXCITATION OSCILLATIONS AND INTENDED TO REDUCE VIBRATIONS OVER A BROAD BAND

摘要

In the system described comprising an oscillating mass and a spring, the spring (20) has a spring rate (C) varying as a function of the excitation frequency Φ. The oscillating system (100) has an oscillating mass (10) in the form of a cylindrical solid body (11) having a practically constant high density, and a spring (20) in the form of at least one annular body (30) which surrounds the cylinder body.
