Resonance frequency of piezoelectrics

Resonance frequency of piezoelectrics

Resonance frequency of piezoelectrics

(OP)
Drej,
I got the following frequencies for Modal Analysis of piezoelectric actuator:   

Set   Frequency(Hz)       DMX
1.     10959             0.75184
2.     16645             1.304
3.     19646             0.644637
4.     24279             1.438
5.     27658             1.88
I used frequency range 10000Hz-30000Hz. So, which frequency is resonance frequency? And how to determine anti-resonance frequency?

Thanks a lot

RE: Resonance frequency of piezoelectrics

the frequency corresponding to your required or expected - m,n(nodal lines and diameters) is the resonant frequency. Look at the mode shapes at these frequencies.

see the below link for anti-resonant frequency
