Yes, every word helps and thank you so much for helping out.
But in your example you had neglected capacitance which allowed you to get away with using I instead of q.
I do not understand your second part. There IS a electrical forcing function (thats the point of my transducer). As I look...
For a piezoelectric crystal with a applied alternating voltage
The mechanical equation is
m\frac{{{d^2}x }}{{d{t^2}}} + r\frac{{dx }}{{dt}} + sx = F
E= -g33.S (S=stress, piezoelectric voltage const, E=electric field)
F= -A.E/g33 (A=Area of resonator, l=hieght)
F= - A.V/(g33 .l)...
my piezo film is electrical to mechanical.
The driving force is the applied alternating electric field which causes the vibration, so I don't think I can use D as the driving force. I will have to think of something else.
By the way is this covered in standard text-books or the literature...
Yes I am familiar with differential equations. I am also aware of the equation for mechanical resonance, but have little clue about electrical circuits beyond the bare basics. Please do help me along.
I looked over the equation for electrical circuits (for series resonance for a start) and...
My first post here. :D
usually this situation does not arise, but I am working on thin piezoelectric films. When a apply a alternating voltage on the electrodes, the film vibrates. Now this constitutes a LCR circuit which has a resonant and anti-resonance frequency. Since it is vibrating, it...
