In this paper, a comparison between two different machine tool columns is presented. The two columns are realized with a different technology: classic metalworking versus metal foam sandwiches. The aim of the experimental tests is at evaluating their different mechanical performances and characteristics, with a particular focus on the damping. The comparison is carried in terms of both modal analysis and wide frequency range excitation, as described in the paper. A new method is introduced by the authors to deem which technology is the best, based on overall energy dissipated in a wide range of frequency.

Abstract
In this paper, a comparison between two different machine tool columns is presented. The two columns are realized with a different technology: classic metalworking versus metal foam sandwiches. The aim of the experimental tests is at evaluating their different mechanical performances and characteristics, with a particular focus on the damping. The comparison is carried in terms of both modal analysis and wide frequency range excitation, as described in the paper. A new method is introduced by the authors to deem which technology is the best, based on overall energy dissipated in a wide range of frequency.File | Dimensione | Formato | |
