Abstract
The analysis of a passive damper employing smart materials is carried out through the description of a concept deviceloaded by a vibrating mass. Such a device is able to damp vibration and to produce electric energy (energy harvesting). Its basicproperties are described in detail and the relationships between damping features and its physical parameters are shown. Theanalysis is carried out by a linear modeling at first, while the comparison to its actual behaviour is exploited to justify a morecareful study where the material non-linearity is considered. Analytical results on the linear model and the spice numericalanalysis of a non-linear model are presented.| File | Dimensione | Formato | |
