The Design of a Cascade of Shoulder-to-Shoulder Mechanical Antiresonances.
Abstract
A vibration isolation module can be made by the alternation of masses and springs to produce a low-pass filter. To decrease the cut-off frequency the masses can be replaced by a cascade of high-Q antiresonant units mounted axially in a cylindrical can. To achieve a high impedance over an appreciable bandwidth, the peaks of the individual response curves are made equal and the successive antiresonant frequencies are chosen to lie shoulder-to-shoulder. Details of a specific design and choice of parameters are presented, as well as the analytical basis. An experimental method for the determination of the viscous damping prior to assembly is described.
