Design of a Simple and Economic Device for the Experimental Verification of the Theory of Multi-Degree-of-Freedom Vibration Systems

Abstract

This contribution presents the design and evaluation of a simple and economic device for experimental verification of the theory of multi-degree-of-freedom vibration systems. The experimental verification of the theory can be carried out, in its most basic way, with the sole help of a tachometer. Of course, if more sophisticated instrumentation is available, it is possible to obtain additional data that verify more thoroughly the theory of the systems at hand. The device is designed so that it can be easily constructed with a small investment, less that $1500, well within the reach of even the less favored universities or technical schools.
