Tuned dynamic counter-balancer with magnetic spring

Abstract

A tuned dynamic counter-balancer (TDC) includes a mount for coupling the TDC to an object for vibration attenuation; a movable assembly configured to move along a first axis and comprising a movable magnetic ring and a movable proof mass; a stationary assembly comprising a stationary magnetic ring and coupled to the mount; and a mechanical spring comprising a flexure bearing that includes two planar springs that connect between the movable assembly and the stationary assembly, wherein the movable magnetic ring and the stationary magnetic ring are arranged coaxially, and wherein a spring rate of the magnetic spring is greater than a spring rate of the mechanical spring.
