Abstract:
A multi-directional tuned vibration absorber, comprising:(a) a base member,(b) a first tuning mass which vibrates relative to said base member predominantly along a first axis and at a first resonant frequency,(c) a second tuning mass vibrating relative to said base member along said first axis at said first resonant frequency and also vibrating along at least two second axes at a second resonant frequency, each said second axis being substantially perpendicular to said first axis,(d) a first elastomeric spring flexibly interconnected between said base member and said first tuning mass such that vibration of said first tuning mass is constrained substantially solely by said first spring substantially restricting motion of said first tuning, mass to allow motion along said first axis only; and(e) a second elastomeric spring flexibly interconnected between said first tuning mass and said second tuning mass, said second spring substantially restricting motion of said second tuning mass relative to said first tuning mass to motion along said at least two second axes.
