The Vibrating Drumhead model displays the analytical wave equation solution for a thin circular membrane with a fixed boundary. The spatial part of the analytic solution u(r,?) is expressed in polar coordinates using Bessel functions and sinusoidal functions. The complete solution to drumhead motion is a superposition (sum) of single frequency oscillatory solutions. These vibrations are known as modes and are enumerated by integers m and n where n is a positive integer that counts the number of radial nodes and m counts the number of azimuthal (angular) nodes.
The Vibrating Drumhead JavaScript Model was developed using version 5 of the Easy Java Simulations (EJS 5) modeling tool. Although EJS is a Java program, EJS 5 creates stand alone JavaScript programs that run in almost any browser.
Please note that this resource requires
at least version 1.5 of Java.
