Active control of sound radiation from a plate using a polyvinylidene fluoride volume displacement sensor
(Acoustical Society of America, 1998-03-01)
This paper presents a new volume displacement sensor (made of shaped strips of PVDF film) and the experimental implementation of this sensor in an active control system. A design strategy for a PVDF sensor detecting the ...
Comparison of two structural sensing approaches for active structural acoustic control
(Acoustical Society of America, 1998-01-01)
A numerical study comparing the use of two structural sensing approaches for sound radiation control is performed on a baffled rectangular plate. The first sensing approach implements an array of accelerometers whose outputs ...
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 ...
Advanced time domain wave-number sensing for structural acoustic systems. Part III. Experiments on active broadband radiation control of a simply supported plate
(Acoustical Society of America, 1995-11-01)
The present work gives further developments and experimental testing of a new time domain structural sensing technique for predicting wave-number information and acoustic radiation from vibrating structures. Most structure-borne ...
Modal sensing of efficient acoustic radiators with polyvinylidene fluoride distributed sensors in active structural acoustic control approaches
(Acoustical Society of America, 1992-06-01)
An experimental investigation was performed to determine the feasibility of implementing polyvinylidene fluoride (PVDF) piezoelectric distributed sensors on the surface of a structure as error sensors in an adaptive ...
