RESUMO

The objective of this work is to achieve a procedure for structural design optimized metal brackets used in the chassis of commercial vehicles, which have in the most of the cases limitations related to product design and manufacturing. Was carried out a bibliographic review of structural optimization main methods, covering problems and solutions related to their use, were also considered the concepts of design for manufacture and assembly. It was proposed a procedure for structural brackets design, using the finite element analysis, parametric, shape and topology optimization. The proposal also notes items such as structural stability; type of element used and to improvement of fabrication and assembly. The procedure was applied in the case study to the development of a shock absorber, which has failed in the field. It was possible to represent the brackets failure of support with the finite element model and optimized structures have been proposed to resolve the failure and confirmed the effectiveness of the proposed procedure at work. One application benefit for topology optimization is the ability of the method to obtain new structures with lower weight and higher stiffness level, and considering manufacturing and assembly needs.
