For this purpose we have studied so many authors to get the parameters which affect the performance of universal joint. We found that factors and parameters such as material of universal joint, Construction and size of the universal joint, Mechanical properties of universal joint, Optimization methods for universal joint system, Innovative design of universal joint are the parameters which can be optimized for getting better results of structural performance enhancement of universal joint. Following the review process we modeled a 3d geometry of universal joint in CATIA V5 and performed structural analysis on ANSYS 14.0. we found out by solution of the analysis that beryllium copper is more suitable for manufacturing of universal joint since we got less total deformation for beryllium copper when compared with the conventional material of universal joint i.e. structural steel. The values of stresses and strains were found to be optimum as well. These all contributed to increase the structural performance of universal joint by using alloy material beryllium copper.

INTRODUCTION A universal joint is a positive, mechanical connection between rotating shafts, which are usually not parallel, but intersecting. They are used to transmit motion, power, or both. The simplest and most common type is called the Cardan joint or Hooke joint. It is shown in Figure 1. It consists of two yokes, one on each shaft, connected by a cross-shaped intermediate member called the spider. The angle between the two shafts is called the operating angle. It is generally, but in01 necessarily, constant during operation. Good design practice calls for low operating angles, often less than 25°, depending on the application. Independent of this guideline, mechanical interference in the construction of Cardan joints limits the operating angle to a maximum (often about i37½°), depending on its proportions. The two fork ends are assembled co-axially with respect to the center block. The pins are assembled into the holes provided in the fork end. they are held in position by means of a collar and a collar ipin. Fig 1.1) universal joint II.
