Book Description
The behavior of dynamic vibration absorbers of conventional and novel design has been investigated experimentally. Transmissibility and relative displacement measurements have been obtained for absorbers attached to a one-degree-of-freedom primary system, and the resultant data have been compared with the predictions of existing theories. The absorbers tested ranged from those possessing a conventional mass-spring-dashpot configuration, to those possessing novel configurations. In all cases, the experimental results were in close agreement with theoretical predictions. The novel configurations included (1) an absorber employing a viscoelastic (Butyl rubber) material as a combined spring-and-damper element, (2) absorbers employing damped laminated beams as spring-and-damper elements, (3) so-called 'dual dynamic abosrbers' -- a conventional, viscously damped absorber in parallel with a less massive undamped absorber, and (4) a single nominally undamped absorber or a pair of nominally undamped absorbers attached to a heavily damped primary system.
