Abstract
Abstract Dynamic vibration absorbers generally have been used to suppress harmonic excitation of plate like structures at a point of attachment and at a given frequency. The vibratory flap is a plate type dynamic vibration absorber and has been developed to suppress plate vibrations over entire plate in more than one frequency. This paper presents an experimental study of transverse vibration of harmonically excited, clamped rectangular plate with vibratory flap. The investigation aims to discover the effect of the mass ratio of the flap on dynamic response of the plate. Consequently, the mass ratio has been optimized to get best attenuation in the first and second target frequencies. The study reveals that, the attenuation in vibration of the plate has increased to a large extent due to the use of optimized vibratory flap. Finally, the experimental results of the plate with optimized flap have been compared with finite element analysis results.
