With the rapid development of the automotive industry and increasingly stringent environmental requirements, lightweight design has become a key technological direction in automotive manufacturing. As a critical component of the vehicle's power transmission system, the structural rationality, lightweighting level, and manufacturing process reliability of the drive shaft flange fork directly impact transmission efficiency, vehicle reliability, and fuel economy. Optimizing its performance is of great significance for vehicle energy conservation and emission reduction. This study employs ANSYS Workbench software to conduct finite element analysis and structural optimization of automotive drive shaft flange forks, evaluating stress and strain under high torque conditions of 24,000 N·m. Analysis reveals that while pre-optimization safety factors exceed industry standards, material redundancy exists. To address this, structural optimization was implemented through material reduction techniques. After optimization, the flange fork achieved approximately 9% weight reduction while maintaining safety factors that still meet requirements. This study validates the effectiveness of finite element analysis in lightweight design for drive shafts, providing theoretical basis and practical reference for automotive component optimization.
