Abstract:
Using the equivalent elastic method, the bending vibration of rectangular ceramic ultrasonic transducer under different conditions is analyzed.The characteristic frequencies of the four sides simply supported conditions are fitted.Under the condition of fixing boundary and free boundary, two fitting formulas of the characteristic frequency of the bending vibration of the rectangular piezoelectric ceramic ultrasonic transducer are obtained. Using the finite element analysis software Comsol to verify the obtained fitting formula, the results show that the characteristic frequency of rectangular piezoelectric ceramic ultrasonic transducer is consistent with the fitting formula.
