Abstract :
The study on finite element analyses of ultrasonic transducer is presented by using the finite element software ANSYS. The transducer is treated as 1/18 3-D finite element analysis modeling to study the ultrasonic transducer acoustic performance. The model of ultrasonic transducer is used in modal analysis and harmonic solutions to understand its mechanical behavior and its natural frequency. Modal identification of the structure can avoid the acoustic resonance mode and reduce the low frequency noise on transducer, provide an effective method for obtaining the acoustic mode of the transducer. The results of finite element simulation analyses show the available of ANSYS in modeling of the simply structure of ultrasonic transducer.
