  • Nonlinear vibration absorber
    Patent number: 4766984
    Abstract: A vibration absorber is provided having a pendulum (12) mounted on a body (21) for oscillation about an axis (13). A pair of resilient members (14, 15) are mounted on the body (21) in contact with the pendulum (12) in preloaded opposed relation with respect to oscillation of the pendulum (12) about the axis (13) and resonant at the frequency of the vibration. A pair of resilient members (16, 17) are mounted on the body (21) to contact the pendulum (12) only upon oscillation of magnitude beyond a predetermined limit.
