Calcaulation of Typical electromechancial Properties of Piezoelectrical
Ceramic Materials
Parameters
of the physical property of our piezoelectric ceramic materials
can be calculated by the following equations (the unit is
in SI system):
Thin disc radial model
Applicable frequency range: 24~11000 kHz
For ¦Õ¡Ý10, consult Product Data Sheet of the company for its
physical property.
Long thin length model
Applicable frequency range: 50~10000 kHz
Note; For 1/b or 1/t ¡Ý3, consult Product Data Sheet of
the company for its physical property.
Longitudinal length model
Applicable frequency range: 10~100 kHz
For L/¦Õ¡Ý2.5, consult Product Data Sheet of the company for
its physical property.
Thin disc or plate thickness mode
Applicable frequency range: 70 kHz~MHz.
Radial mode
If thickness vibration is taken, the applicable frequency range
is 70~500 kHz .
If extending vibration is taken, the applicable frequency range
is 10~200 kHz .
Note: A and C in the equations are coefficients related
to R/r and §Ò. Please refer to Appendix A in GB1194-87.
