| Summary: | A beam-type absorber has been known as one of the dynamic vibration absorbers used to suppress excessive vibration of an
engineering structure. This paper studies an absorbing beam which is attached through a visco-elastic layer on a primary beam
structure. Solutions of the dynamic response are presented at themidspan of the primary and absorbing beams in simply supported
edges subjected to a stationary harmonic load. The effect of structural parameters, namely, rigidity ratio, mass ratio, and damping
of the layer and the structure as well as the layer stiffness on the response is investigated to reduce the vibration amplitude at the
fundamental frequency of the original single primary beam. It is found that this can considerably reduce the amplitude at the
corresponding troublesome frequency, but compromised situation should be noted by controlling the structural parameters. The
model is also validated with measured data with reasonable agreement. |
