The application of impedance curves and admittance circles in the
processing and production of ultrasonic devices is as follows:
1. Ultrasonic transducer: The admittance circle can not appear
parasitic circle, the resonant frequency is as close as possible to
the design frequency, the dynamic impedance is low, the quality
factor Qm should be close to the design requirements, and the
capacitance should match the circuit.
2. Piezoelectric ceramic sheet: The advantages and disadvantages of
the device can be judged directly from the admittance circle
diagram and the logarithmic coordinates. If there is delamination
inside the ceramic sheet or crack occurs, the logarithmic curve
will appear multi-peak. Multiple parasitic small circles appear on
the admittance chart.
3. Ultrasonic horn and mold: Whether the design, processing and
assembly are reasonable or defective, can be clearly seen directly
from the admittance chart.
4. Ultrasonic welding machine: During production and processing,
the state of the welding machine is analyzed by the results of the
admittance circle, and the problems of the welding machine are
found through parameters and graphical analysis.
5. Ultrasonic cleaning machine: When producing and processing, the
choice of vibrator requires the vibration performance to be as
consistent as possible (bandwidth, quality factor, resonant
frequency, dynamic impedance). On the admittance chart, there are
as few parasitic circles as possible or no parasitic circles near
the resonance point. Through the admittance diagram, the transducer
can be manufactured, incoming inspection, bonded transducer, and
cleaning machine for impedance analysis and measurement. The whole
machine measurement of the cleaning machine can calibrate the
static capacitance of the resonant frequency of the machine to
match the power supply, and can analyze its new resonance point,
the impedance after water injection, the capacitance and the
vibration mode of the whole machine.
