Problem statement for the analysis of electromechanical systems by simulation modeling methods

Abstract

The article presents an approach to the complex analysis of electromechanical systems using specialized packages of applied simulation programs. It is shown that the choice of research methodology is due to the complexity and mutual influence of energy processes in electromechanical converters and the absence of verified analytical solutions.The main research stages are defined, including the construction of a geometric model of the object, determination of the problem type to be solved and relevant initial and boundary conditions, justification of defining criteria, modeling of electromagnetic, thermal and hydraulic processes and their analysis. The software packages are based on the classical equations of electrodynamics, heat transfer, energy, motion and continuity. Creation of three-dimensional solid parametric model is implemented in the T-FlexCAD system. The simulation experiment was carried out with the use of SolidWorksFlowSimulation system, that allows to process the initial array of design parameters in conditions of the multiphysics problem statement. The variables were ranked using Statistica, a statistical processing and data analysis program. Simulation results of energy exchange processes at varying geometry of defining design parameters allow to establish dependence of electromechanical system output characteristics on design and dimension relations of system elements parameters and to design high-efficiency electromechanical systems on this basis.
