| Research Abstract |
For a passive isolation system, a friction damper is often used because it is simple, inexpensive and reliable. However, the ordinary friction damper of constant friction force has performance limitation, because the isolation characteristic declines when the friction force is large, while resonant peak becomes large when the friction force is small. Furthermore, the displacement remains apart from the equilibrium position after the disturbance disappeared. In order to overcome above drawbacks, the new type of friction damper is proposed in this paper. The damper is devised to make the magnitude of the friction force proportional to the relative displacement by contacting the inclined lever with rotational spring to the cylindrical block. The experimental and numerical results verified the effectiveness of the proposed mechanism.
