Validação de metodologia de otimização topológica com ferramentas de código livre

Abstract

Optimization is a fundamental aspect of engineering, seeking to find the best solution, considering the sets of variables and restrictions that govern the performance of a system. Topology optimization is a technique that seeks to obtain the best material distribution and performance within a volume. Applied in engineering, it allows the design of lighter and more resistant structures, or surfaces where there is maximum transport flow. Free and open source software are those in which the freedoms of reading, executing, redistributing and modifying their algorithms are granted. When used, they indefinitely guarantee the validity, accessibility and evolution of a project’s files and calculations. With the aim of exploring topological optimization using only free code programs, this work presents algorithms and recent research, where the study and application of topological optimization in projects in sectors such as civil and aeronautical brought benefits, concluding in an implementation in which use only free and open source tools are used to carry out the design, modelling, simulation, optimization, and post-processing of a part, of which a pair was manufactured, original and relieved, that were then subjected to mechanical behavior tests, in order to document the process and validate the programs used to obtain satisfactory engineering results, offering a reliable alternative.
