Exact and approximate analysis of mechanical and mechatronic systems

摘要: Purpose: of this paper is to compare the transients characteristics obtained by approximate method and exact one answer question – if can be used nominate mechatronic systems. Design/methodology/approach: was relevance or irrelevance between considered methods especially concerning pole values characteristics. The main subject research continuous torsionally vibrating bar as a mechanical subsystem system. Findings: approach fact, that solutions fulfill all conditions for bars some only, particularly flexibly beams. Research limitations/implications: linear considered. Practical implications: study point analysis examination torsionaly systems which nominated with similar only. Originality/value: relies on comparison compatibility demanded accuracy, method.
