The increasing adoption of Electric Vehicles (EVs) necessitates innovative approaches to develop efficient and lightweight components. This article presents a comprehensive investigation into the design and structural analysis of driveshafts for EVs, with a focus on utilizing Aluminum Alloy 7075 as the primary material. The design process prioritized critical factors affecting driveshaft performance, including torque transmission, torsional and shear stress considerations and dynamic behavior. A comparative evaluation with Steel SM45C was conducted, considering parameters such as equivalent elastic strain, equivalent stress, total deformation and maximum shear stress. The results showed that Aluminum Alloy 7075 exhibited higher deformation and stress under applied loads, emphasizing the significance of material properties in ensuring structural integrity. Additionally, modal analysis, the natural frequencies and mode shapes were investigated for both materials. The findings revealed varying natural frequencies, with Steel SM45C displaying slightly lower values in most modes, indicating its potential for better resistance to vibration-induced fatigue and resonant frequencies. It is recommendedthat testing should be done to validate the findings and experimentation with hybrid materials to optimize weight, strength, and durability. By comprehensively examining both static and dynamic behaviours, this research offers vital insights for designing driveshafts that meet the unique demands of electric vehicles.
