Özet

Rims are important parts that ensure vehicle contact with the road. They are subjected to a variety of forces and reactions, including the vehicle's load and factors on the road. The designs of the rims, which are produced from different materials to be light and durable, are constantly changing. Fatigue is a form of damage that does not cause sufficient deformation of the part in a single application under repeated or variable loading. Fatigue in rims occurs as a result of being exposed to constantly changing forces while driving. In this study, fatigue analysis of rims with different materials was performed and the fatigue performance of the materials was compared. In order to compare the values between the materials used, the designs were kept constant, and the force and pressure values acting on the rim were also kept constant in the analysis. The design of the rim was created using the CATIA V5 R21 program and the analyzes were carried out using the ANSYS WORKBENCH 18.0 program. The materials used in the analysis of the wheel design were determined as Al 6061, 4340 Steel and aluminum alloy and structural steel, which are widely used in the automotive industry. Important factors in determining these materials are the active use of Al 6061 in wheel production and the use of 4340 steel in areas such as shafts, gears and bearings in vehicles. The reason why aluminum alloys and structural steels are chosen is to compare these general materials with special materials. As a result of the analysis, it was determined that the rims with aluminum material design are 2.88 times lighter than the rims with steel material design, the safety factor is 1.43 times higher, and the aluminum material designs have 1.26 times longer service life. The total maximum deformation of the Al 6061 material design was found to be 2.43 mm, the minimum number of cycles was 774210 and the safety factor was 0.95. After the design with Al 6061 material, it is seen that the design with 4340 steel is the second-best result with a minimum of 596590 cycles. Considering the costs, Al 6061 material designs have been found to be the most suitable option for mini electric vehicle rims
