Application of the GMSH&GETDP Program Complex for the Evaluation of the Stress-Strain State of Electromechanical Converter Structural Elements

Abstract

The work is a continuation of a series of articles that consider the use of open source software Gmsh&GetDP for computer simulation of electromechanical transducer. An assessment of the reliability of particular solutions of problems of static linear elasticity obtained in practice by grid methods using the Gmsh&GetDP software has been performed. Issues of validation of computer models for calculating mechanical stresses and displacements are considered. The results of calculations and comparisons for standard problems of mechanics are presented. The obtained numerical results are compared with analytical solutions. The effectiveness of using the Gmsh&GetDP software for solving particular problems of continuum mechanics is shown. The presented results can be used to form verification and validation matrices in assessing the reliability of numerical models, as well as in the development of new electromechanical transducer. A simulation of a rapidly rotating perforated thin-walled round disk of a power tool engine was performed, which did not reveal an excess of the stress-strain state parameters over the allowable values.
