ABSTRACT:
A vibration absorber, which may be variable frequency, adapted to be fixedly mounted in a fixed vibration prone system. The vibration absorber is of the pendular-type with two dynamic masses suspended in pendular fashion from a base member, and with at least one coil spring acting upon the masses to establish and linearize the vibration absorber natural frequency. The absorber has a selectively constructed base member supporting two dynamic mass members on opposite sides thereof through three or more dually offset pendular connections and with mass member loads being reacted at I-shaped stations in the base member, and with one-piece, solid pin members extending through aligned holes in the base member and mass members, and with two deflected coil spring members imposing internal loads on the mass members to establish and linearize the vibration absorber natural frequency.
