Abstract
In this paper, the concept of tuned vibration absorbers used to a beam structure was analysed by finite element analysis code, ANSYS APDL. The tuned vibration absorbers were attached to the fixed-fixed end beam with four different conditions according to its location of attachment. Modal analysis has been carried out to determine the natural frequencies and naturalĀ mode shapes of the studied beam structure. The effect of tuned absorbers locations on beam vibration characteristics have been studied by harmonic analysis. The vibration characteristics of the beam were discussed with respect to the corresponding tuned absorbers and beam natural modes. It was found that the absorber location affect the beam vibration amplitude greatly. High percentage of vibration amplitude reduction is achieved when the beam amplitude node is avoided.
