TOPOLOGY OPTIMISATION OF HYDRAULIC PRESS STRUCTURE

P.S Burli

Abstract: Topology optimisation is carried out to find the zones of material removal on final size optimised structure. The results are represented and density plots are presented. The zones represented by blue can be removed for better material saving. The density plots are represented showing convergence of solution rapidly in the beginning and slowly in the later iterations. Finally wolf’s law is applied for material removal and addition for better strength. After iterations, the results are presented for vonmises and displacements. The results shows a vonmises stress of around 105 N/mm2 and a displacement value of 1.457mm. The final weight is observed to be around 15501kgs. The results shows efficiency of combination of three techniques in reducing the weigh of machine structures efficiently and useful for industrial applications as a combination. All the results are represented with necessary graphical pictures. The geometry is removed based on topology optimization and results are obtained based on wolff’s law. The structural results are presented.
