Type of Wheel / Rim (Material): Steel and light alloy are the main materials used for wheel manufacturing, however some composite materials including glass-fiber are being used for special wheels like Wire Spoke Wheel, Steel Disc Wheel, Light Alloy Wheel and Aluminum Alloy Wheel.
Same analysis can be performed with different materials by applying load at different areas on the wheel to lessen the weight, which eventually diminishes the overall cost with increase lifetime.
Comparing the stress, displacement, strain, total life and load factor of the testing of various materials, we suggest that aluminum alloy is the best compatible material by the standards of SAE J 175 and ISO 7141-Road vehicle wheels impact test procedure for the aluminium alloy wheels of passenger car.
