Abstract

<jats:p>&lt;div&gt;In the given work the design and stress–strain calculation of housing parts oflarge machines during operation are considered. At the same time, both classicalelectromagnetic forces and technological operations necessary for mechanicalprocessing and assembly of such objects as well as transportation processes aretaken into account for the first time. The task of analyzing of thestress–strain state of the framework was solved in the three-dimensional settingusing the finite element method by the SolidWorks software complex.&lt;/div&gt;&lt;div&gt;The three-dimensional analysis of the stress–strain state of the structure fortechnological operations, namely tilting, lifting, and moving the large DCmachines frame without poles and with poles, showed that the values ofmechanical stresses that arise in the connections of the frame exceed thepermissible limits, resulting in significant deformation of the structure. Thework proposed the modernized frame design with additional stiffeners andre-calculated the stress–strain state of the unit. The analysis, that wascarried out, showed that when performing technological operations, themechanical stresses that arise do not exceed the permissible ones, and alldeformations are in the elastic zone for the given metal.&lt;/div&gt;</jats:p>
