Voice-Coils As Reciprocal Transducers in Structural Health Monitoring Applications

Abstract

The feasibility of using voice-coils as reciprocal transducers of mechanical waves is investigated. It is speculated that these transducers could be used in a seismic network for structural health monitoring purposes, transmitting relatively un-damped low frequency waveforms such as surface waves. This would permit long distances between transducers. The force generation capacity and vibration sensitivity of five types of voice-coil transducers are compared in the lower sonic spectrum. As a verification of the concept, the transducer type evaluated to be the most practical is used to measure the natural bending mode frequencies of a small concrete beam.
