Abstract

This work presents dynamic characteristics of 3-axis active mount featuring the rubber element and the piezoelectric actuator. The rubber element is adopted to isolate external disturbance in the non-resonance frequency range, while the piezoactuator is employed to isolate the vibration in the neighborhood of the resonance. After identifying dynamic properties of the rubber element and the piezoactuator in the frequency domain, the governing equation of the active mount system is derived. Subsequently, generated force and moment of each actuator is evaluated in time domain. In addition, a comparative work between the simulation and measurement is undertaken.
