In order to protect precise machinery from external vibration, various types of vibration isolation system have been proposed by many researchers. For the 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. These characteristics are disadvantageous when the precise position recovery is required. In order to overcome above drawbacks of the ordinary friction damper, the new type of friction damper is proposed in this paper. In the new friction damper, the friction lever mechanism is devised to make the magnitude of the friction force proportional to the relative displacement. This is achieved by contacting the inclined lever with rotational spring to the cylindrical block. When the cylindrical block moves and the angle of inclination of the lever varies, the normal and frictional forces at the contact surface vary according to the displacement of the cylindrical block.
