This study investigates the effects of parasitic mass on the performance of inerter-based dynamic vibration absorbers (IDVAs). IDVAs have been increasingly employed to suppress vibrations in applications of civil engineering structures and vehicle suspension systems. While the masses of the components in a traditional dynamic vibration absorber can be easily compensated for due to its simple layout, the masses of the components in an IDVA can act as parasitic mass and might affect the performance of IDVAs. This can lead to the loss of benefits which is provided by the IDVAs. The negative effect of a parasitic mass in an IDVA can be observed in applications which have smaller inertance values. In such cases, it is important to consider masses of the components while selecting optimal parameters to maximize the performance improvement which can be obtained by an IDVA. In this study, a milling operation is modelled and its machining stability is increased by utilizing an IDVA. The negative effect of a parasitic mass on the performance is shown, and the performance improvement is regained by considering the parasitic mass in the tuning strategy.
