A study on the performance of bending mode piezoelectric accelerometers

The method of eigenfunction expansion is proposed for obtaining an analytical expression for the frequency response of a bending mode piezoelectric accelerometer system. A set of approximate formulae derived relating the sensitivity with system parameters such as length, width, thickness and the seismic to beam mass ratio. Furthermore, the proposed model was experimentally validated using a laser vibrometer system configured for linear displacement measurements. (c) 2005 Elsevier B.V. All rights reserved.
