Аннотация:The object of the research is a part “Flange half of differential case”, which has complex shape of a housing. The subjects of the research are the processes of selection of analogue material, workpiece production method, and justification of the structural and technological parameters of a part, taking into account 3D-modeling of the structure, deformations, displacements, stresses, and safety factor. The selection of analogue material is connected with suspension of production of open-hearth steel grade Mst.6 GOST 380-50. The objectives of the work include juxtaposition of computer models of deformations, displacements, stresses, safety factors of the part made of different analogue materials; comparison of models according workpiece production methods with consideration of material utilization ratio, structural and
technological features of resulting workpieces. For modelling we have chosen the
several types of materials. Research on modelling processes was fulfilled by means
of software of Kompasv17, Solid Works, Solid works simulation. Volumetric models
of parts and workpieces for all studied materials have been created taking into
account the deformations, displacements, stresses, and safety factor. There results
of modelling of “Flange half of differential case” allowed us to make recommendations
for production conditions. These recommendations include the use of steel 45 GOST 1050-2013 as analogue material, hot forging of a workpiece on a horizontal forging
machine, creating of design and technological documentation for the manufacture of
the part.
