3-DIMENSIONAL MAGNETOSTRICTIVE VIBRATION SENSOR - DEVELOPMENT, ANALYSIS, AND APPLICATIONS

This study presents a novel application of giant magnetostrictive mate rial to a three-dimensional vibration sensor. It is called three-dimen sional since it is intended to measure a vibration exerted along an ar bitrary direction. The sensor signals are measured when the sensor att itude relative to the direction of a vibration is varied. Based on the se measurements identification of an unknown vibration is attempted by means of a learning technique. A neural network is employed in order to learn measurement data. Generalization of the trained network is te sted on unknown sample data. (C) 1997 Elsevier Science S.A.
