Abstract

The propeller shaft is a component that transmits torque from the gearbox to the wheels. The complexity in manufacturing the propeller shaft lies in transmitting the torque from the gearbox to wheels in a reliable and vibration-free package. Two major design parameters to be taken into consideration are the weight and strength of the propeller shaft. Reduction in weight without compromising strength is of primary importance. This research paper aims at providing a comparative study on the design and analysis of solid and hollow propeller shafts. The drive system of a car used for SAEINDIA SUPRA is taken into consideration. The study also focuses on propeller shafts manufactured with composite materials, providing better strength and weight reduction. Solidworks are used for designing the parts, and analysis is carried out using Finite Element Methods in ANSYS Workbench. The Fatigue Tool in ANSYS Workbench software is used to analyze its strength, factor of safety, and fatigue life. The results are compared with results obtained by analytical methods. It is concluded that the hollow propeller shaft has a better fatigue factor of safety compared to the solid shaft.
