Improved Behaviour of Accordion Metallic Dampers Affected by the Increasing Number of Layers

In this research for the purpose of the improvements, the effects of increasing the number of accordion tube layers of the Accordion metallic dampers (AMD) was studied. Damping behavior of AMD wasinvestigated by the experimental, analytical and parametric studies. Experimental studies wereconducted on single layer and two layer specimens under axial loading. Analytical studies have been carried out on series of single and multi-layer AMD models; then, those have been verified by theexperimental results. Also, the effect of changing the geometrical parameters on the damping behaviorwith increasing the number of layer was evaluated and ideal geometric model was suggested . The results show increasing the number of layers influences the amount of dissipated energy that is due to a greater stable behavior.
