The article presents methods of testing the dynamic behavior of a machine. The analysis of structural vibration is neces-sary in order to calculate the natural frequencies of a machine, and the response to the expected excitation. The dynamic properties of the machine can be determined by experimental methods. Presents the results of the tractor–baler-wrapper unit tests using operating deflection shapes (ODS) analysis for determining the vibration patterns of machine under vari-ous operating conditions.
