摘要:	The design and construction of wide-band and high efficiency acoustical projector has long been considered an art beyond the capabilities of many smaller groups.Langevin type piezoelectric transducers have been the most candidate of sonar array system applied in underwater communication.The transducers are fabricated,by bolting head mass and tail mass on both ends of stacked piezoelectric ceramic,to satisfy the multiple,conflicting design for high power transmitting capability.The aim of this research is to study the characteristics of Langevin type piezoelectric transducer that depend on different metal loading.First,the Mason equivalent circuit is used to model the segmented piezoelectric ceramic,then,the impedance network of tail and head masses is deduced by the Newton's theory.To obtain the optimal solution to a specific design formulation,PSPICE controlled-source programming techniques can be applied.A valid example of the application of PSPICE models for Langevin type transducer analysis is presented and the simulation results are in good agreement with the experimental measurements.
