On optimization of a car rim using finite element method
This paper presents the optimization of an octopus-type car rim for which critical zones were found first and then optimum thickness was investigated using an elasto-plastic analysis. In this study, three-dimensional finite element method was used for conducting elasto-plastic analysis. In the finite elements analysis, the elements forming the meshes are hexahedral linear elements with eight nodes. Twelve different meshes were used. A quadrant of the rim was utilized due to its symmetric shape. The theoretical results were compared with experimental ones. It seems that the theoretical results are in agreement with the experimental ones. The results are presented in tabular and graphical forms.
