Item Picture
written by Wolfgang Christian
The Driven Wave Machine model simulates a wave machine driven by a sinusoidal oscillator.  The machine consists of horizontal bars welded to a torsion rod that is perpendicular to the bars.  The simulation allows the user to change the number of bars, the drive frequency, and the boundary conditions.   The simulation also allows the user to change the lengths of the bars, thereby simulating the effect of a wave propagating in a non-uniform medium.

The Driven Wave Machine model was created using the Easy Java Simulations (EJS) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.  Double clicking the ejs_mech_osc_chains_DrivenWaveMachine.jar file will run the program if Java is installed.

Please note that this resource requires at least version 1.5 of Java.

The EJS API for handling ODE errors has changed.  I have updated to source code to the new API.
