Contribution of functionally graded material modelling on finite element simulation of rod end parts in automotive steering system
(KOREAN SOC MECHANICAL ENGINEERS, 2016) Toros, Serkan; Altinel, Kayhan
One of the most important manufacturing steps of the rod end materials is the induction process by which the both hardness of the surfaces and the toughness of the part can be adjusted at the same time. In the study, rod end materials which are inducted and non-inducted are simulated in the view of the fatigue life properties. In the simulations, the rod end parts are defined as functionally graded materials where the mechanical properties of the materials are varying with the dimensions. Additionally, the noninducted material properties or fully strengthened material properties are defined for the geometry in order to comprehend the contribution of the definitions on the congruity of the finite element simulation results with the experiments. When the materials properties of the rod end part are defined as functional graded, the simulation results are found to be much more close to the experimental results.
