1.2 Failure modes of Shaft
rear wheel drive and front engine installation has transmission shafts. The weight reduction of the drive shaft can be achieved without increase in cost and decrease in quality and reliability. To achieve such criteria, we need to design composite drive shaft with less weight to increase the first natural frequency of the shaft. This work deals with the replacement of a conventional steel drive shaft with High Strength light weight Composite shafts for an automobile application. In this Study, the drive shaft of a vehicle will be considered for testing and analysis. The modeling and analysis will be performed using CREO and ANSYS software respectively. The analysis will be done for both the materials. Key Words: Torsional Strength, Optimization, FEA, Matrix Composites.
Drive
The main purpose of shaft is that it must transmit the torque from transmission of Differential Gear Box. As its aim to transfer speed, it should be capable of rotating at fast speed as required by the vehicle. It must operate through constantly changing angles between the transmission, differential and axels. Due to its functional conditions, the shaft is subject to torsional and bending forces under operating conditions.

1. INTRODUCTION 1.1 Drive Shafts: Drive shafts are mechanical components that are widely used in vehicle powertrain systems to transmit torque and rotation between different components which are not in line or cannot be connected directly. Drive shafts must have elements, such as splines, gears, grooves and oil galleries, mounted or manufactured on to transmit power or deliver lubricant. The shaft must be strong enough to bear the stress for short term loading, the stress state is quasi static and the drive shaft should be designed to prevent plastic deformation; for long term loading, the stress state is dynamic therefore the shaft must be designed for millions of stress cycles. It is a driveshaft that is designed for applications that call for increased horsepower, so you can hit the road with confidence. Reduced overall weight and rotating mass, delivers improved driving performance and Provides quicker acceleration.
