AB - This study aimed to reduce the weight and improve the performance of an electric vehicle (EV) front axle knuckle by utilizing topology optimization using CFRP materials. Aluminum alloy-based steering knuckles are currently used in major vehicle models production. To further improve the energy efficiency and maneuverability of electric vehicles and reduce unsprung mass, CFRP composites material change and finite element analysis and topology optimization technology were applied to predict weight loss and performance of the front steering knuckle carriers. Through the application of composite materials and the optimal design, we achieved a weight reduction of about 50.7 % compared to the existing aluminum alloy steering knuckle products. From the analysis results under various load conditions (static loading, driving, braking, cornering), it was found that the shape of the CFRP steering knuckle can improve stress distribution and demonstrate excellent safety while maintaining high rigidity and stability. In addition, it is expected that this weight reduction will be applied to contribute to the improvement of vehicle energy efficiency and driving performance. We intend to apply these research results to the industrial field and use them as technical data for the development of new product concepts
