Paper Abstract

A special design theory for distributed piezoelectric actuators is introduced, for reducing noise and vibration in structures. A uniform cylindrical shell is taken as an example of a host structure to illustrate the effectiveness of the design theory. The actuators are designed to reduce the shell structural vibration and interior noise in a wide range of frequencies, for cases where the input disturbance is tonal. Extensive computer simulations were completed to study various aspects of the design theory. In addition, experiments were conducted and the test results strongly supported the theoretical development.
