Purpose: Application of approximate method was main purpose of work to solution task of assignment of frequency-modal analysis and characteristics of mechatronical system. Design/methodology/approach: The problem in the form of set of differential equation of motion and state equation of considered mechatronical model of object has been formulated and solved. Galerkin’s method to solving has been used. The considered torsionally vibrating mechanical system is a continuous bar of circular cross-section, clamped on one end. A ring transducer, which is the integral part of mechatronical system, extorted by harmonic voltage excitation is assumed to be perfectly bonded to the bar surface. Findings: Parameters of the transducer have important influence of values of natural frequencies and on form of characteristics of considered mechatronical system. The poles of dynamical characteristic calculated by mathematical exact method and the Galerkin’s method have approximately the same values. The results of the calculations were not only presented in mathematical form but also as a transients of examined dynamical characteristic which are function of frequency of assumed excitation. Research limitations/implications: In the paper the linear mechatronical system has been considered, but for this kind of systems the approach is sufficient. Practical implications: In article other approach is presented, that means in domain frequency spectrum the analysis has been considered. Originality/value: The mechatronical system created from mechanical and electrical subsystems with electromechanical bondage has been considered. This approach is other from considered so far. Using methods and obtained results can be value for designers of mechatronical systems.
