A new elastomagnetic composite made of alternate layers of magnetic, rigid material and nonmagnetic, elastic one was conceived, produced and studied with the aim of using for the attenuation of spontaneous vibration. The results of the first laboratory tests, performed applying the developed material on a vibrating structure, show the following peculiar characteristics of the novel elastomagnetic composite multilayer: (i) change of rigidity with the vibration magnitude, (ii) vibration attenuation, (iii) shift of the spontaneous vibration frequency of the structure under control. Based on the above-mentioned characteristics, the new composite represents a promising passive element, with auto-adaptive properties, for vibration attenuation.

Abstract
A new elastomagnetic composite made of alternate layers of magnetic, rigid material and nonmagnetic, elastic one was conceived, produced and studied with the aim of using for the attenuation of spontaneous vibration. The results of the first laboratory tests, performed applying the developed material on a vibrating structure, show the following peculiar characteristics of the novel elastomagnetic composite multilayer: (i) change of rigidity with the vibration magnitude, (ii) vibration attenuation, (iii) shift of the spontaneous vibration frequency of the structure under control. Based on the above-mentioned characteristics, the new composite represents a promising passive element, with auto-adaptive properties, for vibration attenuation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
