Topological Optimization Design of the Vertical Machining Center Workbench Based on ANSYS

The vertical machining center workbench solid modal had been built through Pro/E , the static stiffness analysis had been computed by using the finite element software ANSYS, and the workbench static stiffness had been checked according to the calculated result. To lose weight as optimal objective,by using the topological optimization function of ANSYS software, and take into account the stress condition and manufacturing process, the structure of the workbench was improved, the static stiffness was the same as original design. Comparing with the original design, the weight of the optimized structure was reduced by 12%.
