Özet:

In this study, the mechanical evaluation of the front bumper middle bracket of the automobile was carried out by using the numerical method. The finite element method was used in the numerical analysis studies. In the mechanical evaluation process, the deformation response to be given against the loading conditions determined by static structural analysis was obtained. With the design improvement study, steps were taken to reduce the deformation response of the part under loading conditions. Six different materials, which were considered in the material evaluation stage, were included in the numerical analysis under the same boundary conditions and deformation evaluation was made. In the modal analysis study, taking into account the boundary conditions of the part, frequency and deformation values for the first 20 modes were obtained and resonance evaluation was made for the part. In the fatigue analysis stage, the number of resistance to the determined forces of the part, for which the reference material was defined, was calculated. In quality function deployment, the determination of the quality enhancing parameters between the user and the engineering parties for the bracket part and which ones are the most effective were revealed. In the results of the study, a bracket model whose mechanical evaluation has been completed, and the results obtained have the quality to guide automobile part designs.
