Based on the example of a real three-dimensional object (the traverse of a column press) the results of applying the most common topological optimization methods (ESO and SIMP) in terms of accuracy and speed are presented. Two formulations of the topological optimization problem are considered: minimization of compliance with a limit on volume and minimization of volume with a limit on equivalent stresses. Engineering interpretations of optimized structures are proposed and the results of their comparison with the existing version of the traverse are presented.
