Abstracts: This project presents design method and static analysis of propeller shafts. A propeller shaft is used in vehicles as well as in many transmission applications. The objective of the propeller shaft is to transmit the power generated by engine to the differential and rear wheel drive of the vehicle. In which we use two different material for propeller shaft and design and analyse according to it. We use ? steel ( SM45C8) ? HS carbon epoxy composite material The aim is to compare a steel shaft and composite shaft and gives batter from two propeller shaft. Designing of a propeller shaft is made according to tortional, bending and combined theory of shaft design. In composite shaft design some parameters such as critical speed, static torque are studied; the behaviour of materials is considered linear isotropic for steel and orthotropic for composite shaft. Along with the design all the analyses are performed using finite element software (ANSYS workbench). The results show significant points about optimum design of composite propeller shafts. In ansys we analyse the deformation, maximum shear stress and von-mises stress. We represent reduction of weight without significant decrease in vehicle quality and reliability. This is due to the fact that the reduction of weight of a vehicle directly impacts its fuel consumption. The reduction of weight is almost directly proportional to fuel consumption of the vehicle.
