The topology optimization applied to the evaluation study of bracket caliper by using finite element method

The purpose of this article is to analyze the deformation, equivalent elastic strain, and safety factor of a bracket. The research applies a numerical study of topology optimization of evaluation for the structures by using a finite element analysis (FEA) and using aluminum alloy 6061 T6 and cast iron EN GJL 100 materials. The benchmarking of mesh condition by comparing the result with the reference’s data is in good agreement, with error correction less than 5%. On the other hand, the results of the bracket evaluation show that aluminum alloy is more elastic and durable than cast iron. However, cast iron has a higher safety factor than aluminum alloy. The safety factor indicates the structural integrity of a certain material by limiting the maximum force that may be applied. The FEA and optimization results showed that the optimization reduced deformation by 15%. Strain decreased by 21% after optimization. Stress experienced a 25% reduction due to optimization. In this specific topology, weight reduction occurs consistently, resulting in a 31% decrease. This means the topology optimization is effective to evaluate the design structure, such as the bracket caliper, and also shows the reduction in iteration time when the finite element method is applied.
