400 Tonne Hydraulic Press FEA

Mechanika assisted with the design optimisation and structural analysis of a 400 tonne hydraulic guillotine press. The FEA was executed using ANSYS Mechanical Workbench 2020 R2, which was used to model the non-linear cutting action of the blade through the workpiece and to verify the stresses throughout the machine. Mechanika also modelled the hydraulic mechanism…
