Abstract: | <jats:p>Active vibration isolation experiments were conducted using a transducer that measures translational and rotational power transmission from a vibrating mass, through a single-axis active isolator and into a beam. The transducer is capable of measuring forces and moments along six axes and an accelerometer array measures its motion. By combining the measured force and velocity signals the translational and rotational power transmission was measured. Comparisons were made of the effectiveness of several cost functions for minimizing the vibration transmitted into the beam. The results show that active vibration isolation using power transmission as a cost function to be minimized is limited by the phase accuracy of the transducers. The best results were obtained from the minimization of the weighted sum of force and velocity.</jats:p> |
