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 ...
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 ...
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 ...
