Abstract

Vibration control have widely used to suppress the vibration of thin walled structure. There are two different types of thin walled properties such as a thin plate with flexural rigidity and without flexural rigidity. To improve modification of thin walled structure, dynamic vibration absorber (DVA) was introduced to reduce vibration on thin structure. This paper demonstrated experimental force vibration by using exciter motor shaker to investigate the dynamical behavior of a thin walled structure attached with DVA. Experimental results, in terms of modal parameters and vibration reduction performance, are compared with numerical approaches which obtained through a finite element model. The measurement result found that when DVA attached to plate structure the vibration amplitude of the controlled mode are significantly reduced by almost 85% and 94% for single and dual DVA attachment, respectively. It concludes that adding more DVA attached on the structure produce better result in vibration reduction.
