Abstract

Active constrained layer damping has been shown to be an effective way of controlling structural vibration. The success of the technique depends significantly on the strain imparted to the constraining layer by an actuator made of a smart material -- typically a piezoelectric ceramic. The possibility of using magnetostrictive smart patches as actuators is explored in this regard. Comparisons of performance are made between commonly used piezoelectric ceramic and proposed magnetostrictive actuators on the basis of maximum power consumption. It is shown that magnetostrictives offer benefits particularly in the lower frequencies.
