Topological optimization of a part taking into account technological constraints

Abstract

Annotation. In this work, the topological optimization of an aluminum alloy bracket with specified mass restrictions and maximum von Mises stress intensities arising under the influence of load is carried out. The part was redesigned for the additive manufacturing method without forming a support structure, for this, restrictions on the overhang angle between the surfaces of the part and the build platform were used, all surfaces are considered self-supporting. Comparison of strength and stiffness characteristics of parts for bracket options, including both the original one, created by the designer, and those obtained after optimization, taking into account and without taking into account restrictions on the method of technological manufacture of the product, is performed.
