Introduction

The automotive industry has witnessed a significant shift towards the use of aluminum alloy in the production of car rims. This material is preferred due to its high strength-to-weight ratio, corrosion resistance, and aesthetic appeal. However, the failure of aluminum alloy-based car rims can result in significant losses, both in terms of material and non-material. This study aims to determine the cause of failure in aluminum alloy alloy wheels through experimental testing and numerical simulations.

Research Objectives

The primary objective of this study is to investigate the cause of failure in aluminum alloy alloy wheels. The specific objectives are:

To determine the chemical composition of the aluminum alloy used in the car rims
To evaluate the hardness and tensile properties of the aluminum alloy
To analyze the microstructure of the aluminum alloy using metallographic tests
To conduct numerical simulations to predict the behavior of the aluminum alloy under various loading conditions

Research Methodology

The research methodology employed in this study involves a combination of experimental testing and numerical simulations. The experimental testing includes:

Chemical composition tests to determine the type of aluminum alloy used
Hardness tests to evaluate the hardness of the aluminum alloy
Tensile tests to determine the tensile properties of the aluminum alloy
Metallographic tests to analyze the microstructure of the aluminum alloy

The numerical simulations were conducted using Ansys Workbench 14.0 software to predict the behavior of the aluminum alloy under various loading conditions.

Experimental Testing Results

The experimental testing results show that the composition of the aluminum alloy used in the car rims is A413.0 type. The hardness test results indicate that the normal flange area of the alloy wheels has a hardness of 80.9 bhn, while the area that underwent plastic deformation has a hardness of 74.7 bhn. The tensile test results show that the maximum tensile stress is 232,990 MPa with an elongation of 5.48%. The metallographic test results reveal the presence of porosity in the plastic deformation area of the wheels.

Numerical Simulation Results

The numerical simulation results show that the maximum total deformation that occurs is 0.64872 mm from its original form. The equivalent stress simulation produces a maximum stress of 71.023 MPa, while the minimum stress is recorded at 0.039784 MPa.

Factors Causing Aluminum Alloy Alloy Wheels Failure

The analysis and testing conducted in this study reveal that the main cause of failure in aluminum alloy wheels is the presence of porosity in various areas. This porosity causes a decrease in the hardness of materials that experience plastic deformation, thereby increasing the risk of more severe damage. The other factors that contribute to the failure of aluminum alloy alloy wheels are:

1. Porosity

The existence of porosity in the material structure greatly affects the strength and endurance of the wheels. Porosity usually occurs due to imperfect smelting or printing process, which can cause structural weaknesses.

2. Material Quality

The use of aluminum alloy material with inappropriate or defective composition can be a cause of failure. Therefore, it is essential to test material quality before production.

3. Environmental Effects

External factors such as weather conditions, temperature, and humidity can also affect the integrity of the wheels structure. For example, high temperatures can reduce material hardness.

4. Loads that Exceed Design Capacity

Loads that exceed the design capacity can cause structural failure, especially if the wheels experience plastic deformation.

5. Lack of Maintenance

Inadequate maintenance of alloy wheels, such as routine examinations and cleaning, can also trigger further damage that is not detected.

Conclusion

With a deeper understanding of the cause of the failure of aluminum alloy alloy wheels, producers and users are expected to take preventive steps to prevent similar damage in the future. Increased quality control in a better production and maintenance process can contribute to the resistance of wheels, as well as user safety.

Recommendations

Based on the findings of this study, the following recommendations are made:

Producers should implement quality control measures to ensure that the aluminum alloy used in the production of car rims is of high quality and free from porosity.
Users should regularly inspect and maintain their alloy wheels to prevent damage and ensure safety.
Further research should be conducted to investigate the effects of environmental factors on the integrity of alloy wheels.
