ABSTRACT:
An improved vibration isolator for reducing the transmission of vibrations between a supported body and a body suspended from the supporting body employs a pair of rotatable inertial masses that are coupled coaxially by an elastomeric spring. Suspension cables are wrapped around the rotatable masses and connect the masses with the supporting and the suspended body. The manner in which the cables wrap around the inertial masses causes the masses to roll back and forth along the cables when a vibratory load is applied to the cables from either one of the bodies. By appropriate tuning of the masses and elastomeric spring, the isolator can prevent the transmission of vibrations at a given frequency between the two bodies and thereby exhibits a zero impedance or transmissibility characteristic for isolating the bodies from one another insofar as the vibratory loads are concerned at the given or anti-resonant frequency.
