Active vibration and structural acoustic control of shape memory alloy hybrid composites: Experimental results
(Acoustical Society of America, 1990-12-01)
Shape memory alloy hybrid composites have been shown both by analytical simulations and experiments to be effective adaptive materials for active vibration and structural acoustics control [Rogers and Robertshaw, Engineering ...
Broadband control of plate radiation using a piezoelectric, double-amplifier active-skin and structural acoustic sensing
(Acoustical Society of America, 2000-02-01)
The potential of a piezoelectric, double-amplifier active-skin with structural acoustic sensing (SAS) is demonstrated for the reduction of broadband acoustic radiation from a clamped, aluminum plate. The active-skin is a ...
Structural-acoustic control system design by multi-level optimization
(Acoustical Society of America, 1998-08-01)
A multi-level optimization approach for the design of feedforward active structural acoustic control (ASAC) systems is presented. The formulation takes advantage that both the structural response and the acoustic radiation ...
Advanced time domain wave-number sensing for structural acoustic systems. II. Active radiation control of a simply supported beam
(Acoustical Society of America, 1994-06-01)
A real time structural acoustic sensor and associated signal processing is developed and applied to the active control of sound radiated by a simply supported beam. The sensor consists of multiple accelerometers mounted ...
