MULTI-OBJECTIVE OPTIMIZATION AND INVESTIGATION OF MATERIAL EFFECT FOR AUTOMOTIVE GOR PART
 
Material development studies in the automotive sector have gained attention in recent years. Based on this, computer-aided engineering (CAE) analyses are performed before prototype production and material validation can be achieved in a virtual environment. Therefore, a balance must be maintained between design optimization and material selection considering the strength and displacement issues. The motivation of the study is to select the optimum material for the Gor part used in passenger cars according to the analysis requirements with the Ls Opt program and to investigate the effect of different materials on the strength. In our study, a typical material selection difficulty for different engineering applications is also discussed. Ls Opt is used in our paper in order to solve a multi-target optimization problem by considering factors such as material properties, material cost, weight, durability and efficiency. DP600, DP800 and WSS-M1A367-A22 steels were selected as target materials and a multi-target optimization algorithm was used to determine the most appropriate material combination considering the related material options. Besides, different thickness ranges were taken into account for the analyzed material groups by conducting finite element analysis and the effect of the design process on durability was examined. Displacement values were characterized for 3 different steels analyzed and it was determined that the lowest desired displacement was for WSS-M1A367-A22 steel. In addition, the displacement value of DP600 steel is worse than that of DP800 and relatively higher carbon and higher chromium have impact on mechanical properties.
