Journal of Achievements in Materials and Manufacturing Engineering

2008

Vol. 28, nr 1

43-46

Purpose: The purpose of this paper is application of approximate method of solving the task of assignment the frequency-modal analysis and characteristics of flexibly vibrating mechatronic system. Design/methodology/approach: The main approach of the subject was to formulate and solve the problem in the form of set of differential equation of motion and state equation of considered mechatronic model of object. Galerkin's solving method has been used. The considered flexibly vibrating mechanical system is a continuous beam, clamped at one of its end. Integral part of mechatronic system is a transducer, extorted by harmonic voltage excitation, to be perfectly bonded to the beam surface. Findings: The parameters of the transducer have important influence on values of natural frequencies and on form of characteristics of the discussed mechatronic system. Research limitations/implications: In the paper the linear mechanical subsystem and linear electric subsystem of mechatronic system has been considered, however for this kind of systems the approach is sufficient. Practical implications: The methods of analysis and obtained results can be base on design and investigation for this type of mechatronic systems. Originality/value: The mechatronic system formed from mechanical and electric subsystems with electromechanical bondage has been considered. This approach is different from those considered so far.

In this paper three methods were applied in order to synthesize the dynamical characteristics of the longitudinally or torsionally vibrating mechatronical system with cascade and branched structure. Obtained recurrent forms for the dynamical characteristics determinate a base to theirs programming in order to obtain the dynamical flexibilities for n-bars longitudinally or torsionally vibrating mechatronical systems.
