Reprojeto estrutural de um posicionador de solda de uma célula robotizada com aplicação de ferramenta de otimização topológica

Abstract

Robot welding operations have increased the demand for highly robust and safe mechanical components. The weld positioner is a key element that directly influences the quality of the final product. This work proposed the structural redesign of a weld positioner in a robotic cell. The weld positioner, a structure that precisely controls and maintains the position of an object during the welding process, was analyzed and tested to ensure its stability under maximum operating loads. Using the Finite Element Method (FEM), Meshless Method and topological optimization techniques, it was possible to develop a detailed model of the positioner and simulate its behavior under different load conditions. The application of topological optimization allowed the definition of a new geometric concept for the structure, enabling the development of a new set of plates that make up the internal and external structure, resulting in a mass reduction of approximately 26%. The analyses carried out showed that the new positioner model maintained its ability to withstand operational loads, with maximum displacements of less than 1 mm under maximum load.
