Improvement study of Style steel wheel durability in Multiple pothole impacts

This study focuses on improving the durability of steel wheel rims subjected to Multiple Pothole which is commonly found in Indian village roads - a critical scenario affecting vehicle safety and wheel lifespan. Initial steel wheel designs often face significant deformation or failure under repeated strikes and resulting in tyre air loss due to wheel bend, prompting the need for enhanced performance standards. In this research, a combination of finite element modelling, experimental impact testing, and material optimization strategies were employed to assess and improve the structural integrity of steel rims. Key parameters such as rim profile geometry & material composition were systematically varied to evaluate their influence on impact resistance. Results demonstrate that strategic design modifications and material enhancements can significantly increase the rim's ability to absorb energy and resist bending without substantial weight penalties. The findings offer practical guidelines for the automotive industry to produce more robust steel wheels, enhancing vehicle safety and reducing warranty costs associated with curb impact damage. The improved steel wheel rim design was validated through double curb impact testing, successfully meeting performance criteria and demonstrating enhanced durability without failure
