Need help in simulation of a mini project using piezoelectricity

[Jeffrey1627]

Hello everyone.
I have a small project about piezoelectricity but Im a little stuck and don’t have enough time. My project is about studying the potential vibration control in a tennis racket using piezoelectric materials. The piezo role is to detect the vibrations then it will turn it to electrical signal, then it will get recaptured and by a microcontroller, the piezos will get enough voltage to then vibrate in the opposite way in order to cancel the vibrations immediately.

Now, I want to do a simulation of all this because it’s just hard for me to do it manually at home, but I don’t know what software to use and how to do it, idk even if it’s feasable and I need help.

What frequencies do tennis racquets vibrate at after hitting a ball?

Would you start there first?

I don't know but imagine the frequencies are all sub 15kHz or thereabouts. Would destructive ultrasound frequencies work?

How much power would you need to dampen the string vibration and how fast would you want it to happen?

I may be wildly wrong but this is my guess at an approach.

I appreciate the reply! I have a project that I should do as a uni assignment and I found this one very interesting and already fixed, so I can’t really do another project or even change the approach of this study. I just need a software that can simulate this happening like in real life, then I will get real data from the software about the different vibrations that were canceled and how fast the response was for each one.

It is a mechanical system, the racket, you would need to model the racket frame if not also the strings in a mechanical CAD simulation package. How to do that accurately would require significant effort. The piezos would almost be an after thought compared to the racket.
