The article proposes an approach to computation of parameters of dynamic vibration neutralizer and absorber in order to suppress machine tool vibrations during machining process. The approach is based on multi-body model of the machine tool in a state space form and additionally attached passive absorber in a parametric state space form. Such a representation is suitable for fast optimizations of the absorber parameters and other numeric experiments with the model. The article presents comparison of optimized dynamic vibration absorber and neutralizer. There were also compared two approaches to the build of the objective function for the balanced improvement of the behavior in both X and Y axis.

Keywords: machine tool; vibrations; passive absorber; optimization; objective function
