Theoretical and experimental modal analysis of the cylinder unit filled with PUR foam

Popis výsledku v původním jazyce

In the paper the dynamic properties of the cylinder unit as a part of the theatre scenography lifting mechanism have been investigated. The noise and vibration problém of the cylinder unit when lifting loads turned out to be the crucial limit in application of the whole mechanism for lifting scenography elements on a theatre stage. The construction of the mechanism was examined and the main source of noise was identified as the cylinder unit. Theoretical modal analysis confirmed that thesis. Experimental modal analyses of the hollow cylinder unit as well as the cylinder with the PUR foam filling were performed. The results showed significant improvement of the dynamic properties due to the vibration amplitudě decrease for the first three vibration modes of the filled cylinder. The research method of modal analysis turned out to be highly efficient in dynamic properties determination in the industrial practice. The method of improving the dynamic properties of the mechanical construction byfilling dosed regions with PUR foam is of a great importance for industrial application and seems to be economically effective.
