Abstract

Finite Element Analysis is used to simulate the resonance modes of the flexural mode transducer and the simulation is compared with experimental results. The computer simulation of amplitude distribution gives opportunity to optimize transducer performance, such as polar pattern and transducer ringing. An electrical matching circuit provides optimal performance of the flexural mode transducer. Self-cleaning operation enables the transducer to be used in harsh environments. Addition of nylon cover improves self-cleaning operation and produces a piston-like vibration of the transducer face
