Hi, I have what I think is a simple question that I cannot find the solution to. I am modelling a piezoelectric actuator with a stack system (PZ disc, electrode, PZ disc, electrode, etc.), but I am unable to figure out how to properly apply the sinusoidal voltage to the system.
I would like to apply a sinusoidal voltage (let's say 100V to -100V) to half of my electrodes and keep the others as my ground at a frequency which I previously identified through modal analysis.
Could someone assist me with this? Thanks as this is my first piezoelectric simulation.
So simple, in the global definition, add a rectangular pulse and specify the pulse width such that it only goes high during one cycle.period of your sinusoidal signal. Then add an user defined function where you will specify your formula. you can specify sth like: 100*sin(2*pi*f0*t)*rect(t). This will give you one cycle of the sinusoidal signal. you can use any name for this function and call it where ever you want maybe in electrical potential BC.
could you please specify the problem in more detail Mr. Higgins?
You may also provide a diagram and specification of your actuator in this particular case.
Sorry for the delayed reply. I was able to use a method similar to that recommended by Mr. Zangabad to apply the voltage. Thank you both for your help Sirs.
