I am working on some acoustic synthesis models of real world instruments. The Bessel Function zeros give the vibration modes of a circular membrane, which can be used to model a drum head or even roughly a cymbal.
However, much of a drum's sound (especially snare) comes from the "ring" of the shell itself, which is a cylinder.
I found an article from 1996 which seems to propose a method of calculating expected modes of a cylinder using ANSYS. I have attached it for reference.
However, I have never used ANSYS and the math is a bit over my head.
I will learn whatever I have to, including ANSYS however, to get the answer. I am wondering how I should go about this and if there are easier ways to model this problem, now that it is 22 years later from that article.
Any suggestions?
Thanks.
