A shape memory alloys based tuneable dynamic vibration absorber for vibration tonal control
The absorber architecture is extremely simple: it consists of a clamped SMA wire and a concentrated mass. Two reference structures have been considered: a typical aeronautical aluminium panel and a fibreglass panel. In the first part, the investigated concept is introduced with a short presentation about the SMA main properties. The realisation and experimental characterisation of the device are then presented. Its implementation, a report on the experimental campaign and the presentation of the attained results conclude the work, together with a discussion on the achieved results and the next investigation steps.
