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
