Looking for PMN-PT resonance frequencies Answered
I am learning simulation by Onscale software. I have little experience using COMSOL but just for electrical field simulation.
Now, I am trying to simulate the vibration for PMN-30PT single crystal(0.08*2*t mm).
I want to know in each thickness (such as t= 1mm, 0.5 mm, 0.2 mm, or 0.1 mm) has different resonance frequencies.
For example, I am looking for a 9 MHz central frequency design. I don’t know which thickness is the best design for a 9 MHz transducer.
Based on the thickness mode resonance frequency, the sample thickness is between 0.3 mm to 0.2 mm.
I do the simulation and get some results. However, the simulation results (impedance and phase) are totally away from the real case.
I am not sure which part is wrong. Could you help me to figure it out?
It supposes to be an easy model, but I can’t get the right simulation.
I am looking forward to hearing from you.
