Utilising the new FREE\u00a0topology optimisation ACT-extension, one can explore new innovative ways to reduce mass that were not available before.\u00a0The DoE (Design of Experiments)\u00a0approach may not be feasible if the design’s shape\u00a0is not\u00a0yet defined,\u00a0while creating CAD models to capture all the potential design possibilities may be impossible.<\/span><\/p>\n

Now imagine starting with an arbitrary volume and having each element within\u00a0either turned on or off to create the most optimum shape, taking into consideration\u00a0the applied loads, boundary conditions, and\u00a0design constraints (such as, a maximum displacement\/stress limit required for the design) to achieve an overall\u00a0weight reduction.<\/span><\/p>\n

In Shape Optimisation, we have constraints and objectives. Constraints\u00a0define the optimisation’s bounds, while\u00a0objectives are essentially the goal of the optimisation problem.<\/span><\/p>\n

In the following example, the imposed loadings on the Bell Crank\u00a0must not result\u00a0in excessive deformation, but the component is way too heavy\u00a0so mass needs to be removed.<\/span><\/p>\n
