Effect of the environment on the dynamic properties of simple parts
Nováková, Soňa ; Himr, Daniel (oponent) ; Habán, Vladimír (vedoucí práce)
The dynamic characteristics of the object are influenced by the changes of the envi-ronment. The objective of this report is to examine how the changes of the environment influ-ence the dynamic characteristics of the object. The main aim is to compare the natural fre-quencies of the object when suspended and then actuated when being surrounded by air and submerged in water. The object in question is a cylindrical pipe, which was gradually short-ened during the experiment. These changes in size also affected the natural frequencies and the mode shape, which is discussed as well. The results of the experimental modal analysis are compared to calculations run in ANSYS software.
