| Abstract: | The dynamic analysis of the machining center is carried out by the FEM in this paper. The main modes, which mostly influence the characteristics of the machining center, are identified. Further more, tuned dampers based on the modal parameters of these modes are designed to suppress the machine vibration. It is clear from the analysis that the dynamic properties of the machine have been improved by installing the tuned dampers on it. |
