Khalane and Miss. This article presents a method of modeling small-dimension rubber torsional vibration damper using MATLAB/Simulink, mathematical model of the damper and simulation studies. of vibration problems, and hopefully to provide both the novice and the experi-enced Matlab programmer a few new tricks with which to attack their problems of interest. Topics include single-degree-of-freedom free vibration, model development by modal analysis, measurement techniques, and receptance coupling.
