Effect of different inertia-type piezoelectric actuator masses to reduce the vibration of an active suspended handle.

In this paper, the effect of different masses of the inertia-type piezoelectric actuator is investigated within the general operating frequency range of most of the power tools. The inertia piezoelectric actuator was applied to the active suspended handle system to reduce the shaker-excited vibration for both frequency independent and dependent excitations. For the condition of frequency independent excitation, the results showed that the acceleration of the active suspended handle was reduced up to 39.69% for 45 g of inertia mass. Inversely, for the frequency dependent excitation condition, the maximum vibration reduction i.e., 34.98% was achieved by 95 g. [ABSTRACT FROM AUTHOR]
