KEYWORDS: Solidworks, ANSYS Workbench, Rigid Flange Coupling, Finite Element Method (FEM). I. INTRODUCTION Coupling is a device used to connect the shafts together for the purpose of transmitting power and torque. Generally,couplings are used for connection of shafts unit that are manufactured separately. Such as motor and generator; electric motor and centrifugal pump etc. [1] Due to the inconvenience in transportation of shaft of greater length, it becomes necessary to join two or more shafts by means of coupling. The shafts that are connected by coupling should be easy enough to assemble and dismantle for the purpose of repair and alterations.The severe failure due to shearing of bolts head, key head, nuts and other projecting parts may cause accidents. So, it should be covered by giving suitable shape to the flanges or by providing guards. The shaft to be connected by the coupling may have collinear axes, intercepting axes or a parallel axes with a small distance in between them. [2] The flange coupling is further classified into two types; Rigid and Flexible Coupling.Rigid flange couplingconsists of two separate grey cast iron flanges. One keyed to the driving shaft and the other to the driven shaft by means of nuts and bolts arranged on a circle concentric with the axes of the shafts. [3] There are two types of rigid flange couplings; Protected and Unprotected rigid flange coupling. In a protected rigid flange coupling, a protective circumferential rim covers the nut and bolt head. So in any case of failure of bolts during operation, broken piece of bolt will dash against this rim and eventually fall down, protecting the operator from any possible injuries.In unprotected rigid flange coupling such protective circumferential rim is absent. So, in any case of failure of bolts, it may hit and harm the operator.

ABSTRACT: A Coupling is a device which is responsible for the operative power transmission between two shafts
rotating at particularRPM. Coupling is used to connect two different shafts at their end and can slip or fail depending
upon the torque limit. It is the crucial part of any power transmission and may last for very long time if designed and
maintained properly. The present study of this paper is to reduce the maximum shear stress by selecting a suitable
material for flange coupling. For this purpose, modelling of the rigid-flange coupling is carried out in Solidworks and
