El MMA ha demostrat les seves capacitats com a mètode
doptimització per a problemes estructurals. La proposta vol proporcionar a lalumne el coneixement sobre el mètode i la seva implementació a través del codi original del seu desenvolupador en MATLAB. Les aplicacions en problemes estructurals serviran per consolidar i entendre el funcionament del MMA i ser capaços de definir noves aplicacions. Pla de treball El projecte es desenvoluparà en diferents fases: - Estudi de lestat de lart: o Optimització topològica per a problemes estructurals o Visió general dels mètodes doptimització - Mètode de les asímptotes movibles; MMA - Implementació en MATLAB del mètode - Validació de la implementació - Aplicacions del mètode |

Overview (resum en anglès): | |
Application of the Method of Moving Asymptotes
The Method of Moving Asymptotes (MMA) has been revealed as a useful tool for solving approaches that appear in the field of topological optimization. In structural problems, from certain limitations set within a domain, we can get the design variables that maximize or minimize a previously chosen feature. Thus, it is possible to make parts or structures optimal for the application for which they are required. This project aims to study the validity of MMA for topological optimization problems performing a theoretical and numerical study of the method and implementing codes provided by the original developer, noting that the results are valid and accurate enough for the requirements that have been previously established. The project has been developed in three phases. First, we have proceeded to a study of the state of the art, which defines the concept of topological optimization and performs an overview of the current existing methods. We have also studied the advantages and disadvantages they have and mentioned some examples of these methods with their basic characteristics and some particularities. Second, we have defined the Method of Moving Asymptotes (MMA), his mathematical procedure and its theoretical base of operation. Then, we have implemented the codes provided by the developer of the method using the program MATLAB, verifying the performance and potential problems that may arise, achieving a more comprehensive understanding of the method and its operation. Finally, we have developed new optimization problems and we have generated the appropriate codes based on the method MMA, obtaining suitable solutions. Thus, the usefulness of the method has been validated and has been shown the consolidation of knowledge, in addition to establishing new possible applications. |
