Autoři :SMOLÍK L., HAJŽMAN M.
Abstrakt :Rotor dynamics is an interesting and useful engineering area with many types of industrial applications. An experimental verification of rotor models is a necessary part of rotor analyses and various calculations. The common sizes and weights of rotors, which can be found e.g. in the energy production industry, allow to employ a standard methodology of an experimental modal analysis. However certain applications with rotors of small weights lead to the usage of alternative measuring methods suitable for the identification of rotor eigenfrequencies. One of these methods, which is characterized by the measuring of noise, is introduced in this paper and the results for a particular rotor is presented. Moreover the tuning of the finite element rotor model on the basis of such measured values is shown.
