ABOUT THE USE OF SHAPE MEMORY ALLOYS IN VIBRATION DAMPING

Vibration damping for structures is an important issue, because it mitigates hazards, increases the comfort of people who use the structures, and enhances the reliability, and performance of structures. The paper presents the concern of the authors to realize a vibration-isolated workstation for own use. In this mean the authors have both modelled and experimented small scale devices, usable in vibration damping and control. The theoretical models use the spring(s)damper(s)-mass model. The results of simulations were compared whit experiments made using Ni-Ti alloys with different shapes. We concluded that the used theoretical model present sufficient accuracy for practical issues. Regarding the device's shapes, the best results were obtained for semi-cylindrical elements. The mass of the staff plate and equipment placed on it has also an important role in the damping system.
