摘要

A finite element approach to the simulation of the dynamicnresponses of electromagnetic induction transducers is presented. Thenelectromagnetic induction transducer for intense sound radiation isnconsidered as a transient coupled magneto-mechano-acoustic system, innwhich nonlinear effect of the acoustic field is also included. Thenaxisymmetric finite element formulation is developed and solved in thentime domain. Some numerical examples are demonstrated for thentransducers with a circular plate radiator and a shallow spherical shellnradiator. Experimental verification is then made for the fabricatednmodels of small scale. The comparison proves the validity and thencapability of the present numerical modelling
