Structural and Material Analysis of an Automobile Wheel Rim using ANSYS Sudhakar Mishra1, Dr. L.P. Singh2 1M.
Tech Student, Thermal Engg. (Mechanical Engineering Dept.), SHUATS, Prayagraj, India 2Associate Professor (Mechanical Engineering Dept.), SHUATS, Prayagraj, India ---------------------------------------------------------------------***---------------------------------------------------------------------Abstract - A rim model was made with Solidworks 2018 software. Load analysis was performed based on the input data in ANSYS software. The results obtained after performing the analysis shows the difference in the structural behaviour of the rim model. A standard rim size according to SAE of 17 inch is taken and analysed. For analysis, ANSYS WORKBENCH 19.2 software is used. Fixed support is applied on the 5 lug holes. Pressure of 0.34474 MPa (50 psi) is applied on the outer surface (wheel barrel). Meshing is performed, then materials are applied. For the ease of work, four different ANSYS workbench files were created with different materials. Parameters of fixed support and pressure were applied on the model with different materials (Steel, Aluminum alloy, Titanium alloy, Magnesium alloy).
4.
It should be possible to remove or mount the wheel easily.
5.
Its material should not deteriorate with weathering and age. In case the material is susceptible to corrosion, it must be given suitable protective treatment.
Key Words: Alloy wheel, wheel rim, SOLIDWORKS, ANSYS Workbench, stress analysis, deformation analysis.
The following are the main functions of a wheel rim:
1. DEFINITION OF WHEEL A wheel is a circular block of a hard and durable material at whose center has been bored a circular hole through which is placed an axle bearing about which the wheel rotates when a moment is applied by gravity or torque to the wheel about its axis, thereby making together one of the six simple machines. When placed vertically under a load-bearing platform or case, the wheel turning on the horizontal axle makes it possible to transport heavy loads. Alloy wheel rims are automobile wheels which are made from an alloy of aluminum or magnesium metals or sometimes a mixture of both. Difference between Alloy wheels rim and normal steel wheel rim is due to their low weight, which improves the routing and the velocity of the car.
1.
Transferring torque (braking and acceleration)
2.
Support mass (support the mass of the motor vehicle)
3.
Adds mass (damped mass for diving comfort)
4.
Dissipating heat (due to braking)
5.
Absorb Impact (road hazard)
6.
Conserve Energy (potential energy in momentum)
2. METHODOLOGY: The following parameters were considered during modeling of the Wheel listed in table 1. A standard rim size according to SAE of 17 inch is taken and analysed as shown in figure 1. The wheel has 5 major spokes which are split in two parts. Table -1: Parameters of model of the wheel rim. Parameter

1.1 Requirements and Functions of a wheel: The various requirements of an automobile wheel are: 1.
It must be strong enough to perform the above functions.
2.
It should be balanced both statically as well as dynamically.
3.
It should be as light as possible so that the unsprung weight is least.
