In this work the design and stress–strain calculation of housing parts of large
machines during operation are considered. At the same time, both classical
electromagnetic forces and technological operations necessary for mechanical
processing and assembly of such objects as well as transportation processes are
taken into account for the first time. The task of analyzing of the
stress–strain state of the framework was solved in the three-dimensional setting
using the finite element method by the SolidWorks software complex.
The three-dimensional analysis of the stress–strain state of the structure for
technological operations, namely tilting, lifting, and moving the large DC
machines frame without poles and with poles, showed that the values of
mechanical stresses that arise in the connections of the frame exceed the
permissible limits, resulting in significant deformation of the structure. The
work proposed the modernized frame design with additional stiffeners and
re-calculated the stress–strain state of the unit. The analysis, that was
carried out, showed that when performing technological operations, the
mechanical stresses that arise do not exceed the permissible ones, and all
deformations are in the elastic zone for the given metal.
