Purpose: The purpose of this paper is to compare the transients of characteristics obtained by the approximate and exact method and to answer to the question - if the method can be used to nominate the characteristics of mechatronic systems. Design/methodology/approach: The main approach to the problem is to nominate the relevance or irrelevance between the characteristics obtained by different methods - especially the relevance of the pole values of characteristics. The main subject of the research is the continuous torsionally vibrating bar considered as a mechanical subsystem of the mechatronic system. Findings: The values of zeroes and poles of continuous mechanical system depend on the boundary conditions. Foreseeing approximate solutions fulfill some conditions only, particularly for flexibly vibrating beams. Research limitations/implications: The linear continuous torsionally vibrating bar is considered. Practical implications: The main point is the analysis and the examination of torsionaly vibrating continuous mechatronic systems which characteristics can be nominated with approximate methods only. Originality/value: The originality of the approach relies on the comparisation of the compatibility of the characteristics of the mechatronic and mechanical systems with demanded accuracy, nominated with the same approximate method.
