PROPERTIES OF TUNED VIBRATION DAMPERS

Abstract

Measurements are desoribed which indicate the damping effectiveness of a light-weight vibration damping device which can be tuned to provide optimum damping over a selected frequency range. The criteria for comparison of spot dampers by means of vibration decay rate measurements are developed, and the relative damping effectivenesses of two types of spot damper are evaluated in terms of Air Force requirements. It is concluded that extraordinarily effective vibration dampers of this type can be fabricated for aircraft application pending a materials survey to determine the optimum compromise between damping effectiveness and other physical requirements.
