An economic way to attenuate vibrations of a boring bar is by inserting a tuned mass damper into the free end and maximize its effect by pre-tuning. When tuning the damper, it is important to aquire the damper’s dynamics by frequency response function measurement. However, for small or liquid based dampers it is impossible to carry out frequency response function measurement directly. In this thesis, a noncontact measurement method for estimating damper’s dynamics is developed. The method is tested in simulations, using models of real boring bars, with promising results.
