Graphs different category of subsystem as models to synthesis of transverse vibrating beam - system

Buchacz A.

Journal of Achievements in Materials and Manufacturing Engineering

2010

Vol. 43, nr 2

644--650

Purpose: of this paper is modeling by different categorygraphs and analysis of vibrating clamped - free beam as subsystem of transverse vibrating beam-system by the exact and approximate methods and creating the hypergraphs of the beams in case of presented methods of analysis. Design/methodology/approach: was to nominate the relevance or irrelevance between the characteristics obtained by considered methods - especially concerning the relevance of the natural frequencies-poles of characteristics of considered beam. The main subject of the research is the continuous clamped - free beam with constant cross sections as a subsystem of transverse vibrating beam - system. Findings: this approach is fact, that approximate solutions fulfill all conditions for vibrating beams and can be introduction to synthesis of these systems modeled by different category graphs. Research limitations/implications: is that linear continuous transverse vibrating clamped-free beam is considered. Practical implications: of this study is the main point is the introduction to synthesis of transverse vibrating continuous beam-systems with constant changeable cross-section. Originality/value: of this approach relies on application approximate methods of analysis of clamped - free beam and modeling the one of transformed hypergraph.

Rozważa się model belki swobodnej drgającej giętnie. Belka jest obciążona harmoniczną siła poprzeczną i znajduje się w ruchu, który w pracy jest traktowany jako ruch unoszenia. Belka jest wykonana z jednorodnego tworzywa a jej przekrój poprzeczny jest całkowicie wypełniony. Opisano ruch belki z uwzględnieniem jej odkształcalności oraz wpływu ruchu unoszenia.

In this thesis the transversally vibrations of the beam were considered. The beam was loaded by the harmonic bending force and one was in motion which was considered as transportation. The beam was made by homogenous elastic material and one has a full section. Analysis of mechanism's vibrations was made with taking into consideration the transportation effect.
