Metodologia para otimização topológica de polias usando Ansys APDL

Abstract

The present work develops a method of topological optimization, for application in a transmission pulley used in an energy efficiency team, with the purpose of reducing mass while still maintaining a satisfactory resistance for its application. For this, some recurring problems with this type of optimization were discussed and from there possible solutions were presented. Regarding the application, a methodology was presented that seeks to simplify the use of the results obtained in this type of optimization, taking into account the importance of obtaining geometries that are easy to manufacture at the end of the process. The study was developed through finite element analysis and using the Ansys 18.2 program in APDL language, with the main tool being the use of the TOPDEF command and the TOPITER, which are responsible for much of the topological optimization process, in addition to all the others parameters and codes used are presented and discussed, at the end a wide variety of results were obtained with variations in quantity of rays, percentage of material removed, number of iterations among other parameters, finally this work results in a new opening for improvements of the method code and applications. However, the final results demonstrate the advantages of using topological optimization, contributing significantly to the final result of a project.
