ABSTRACT
The article describes the mechanical system developed at our department. It examines shaft couplings and their impact of torsional oscillation and vibrations on noisiness of the mechanical system. The noisiness of the mechanical system is compared with the vibrations measured in a given mechanical system. The article also presents the apparatus used for measurements. Every device is described in detail and highlights its use in practice. These devices were used for measurements in the laboratory and the results of the measurements are shown in the graphs. From the results, we can evaluate that vibration and noisiness are closely related. A detailed evaluation of the changes of individual values using a variety of shaft couplings is summarized at the end of the article.
