LITRATURE REVIEW: Abstract - Tractor and trailer is a very useful component in 2Assistant
agriculture field and transportation the goods in rural and urban area. A knuckle joint which is used to connect the tractor and trailer .It consist of eye forks and pin .The effective design of the component which is attached to the trailer and tractor .When the vehicle is motion the forces is acting on the joint is tensile and it’s opposite it is compressive. In the knuckle pin stresses are developed during its operation. Force acting on the fork and pin is calculated by the theoretical study and analytical method. Subjected to high stresses in pin going to be study by using catia V5 and finite element method to be used in analysis.
Key Words: knuckle joint, F.E.A, catia V5, ANSYS software 1.INTRODUCTION Knuckle joint is a joint which is used to connect two rods under the tensile load. It is a type of hinged joint. However , if the joint is instruct , it may backing a compressive load. This joint can be easily connect and disconnect for adjustment or repairing. The example of knuckle joints are: tension link in bridge structure , tie rod joint of roof truss , link of roller chain , jib crane and railway wagon. This joint permitted limited angular movement between roods about its axis of the pin.
Dharpure and mate: They are working in the study and analysis of the failure condition in knuckle joint which is used in railway couples overdue to shearing as the part of the knuckle pin that a pin is convenient for working of knuckle and there are no loading case is obtained over it however due to the manufacture of the knuckle and their cause of failure of knuckle is initiated in their paper. They using finite element method for describe the possible failure and elasticity required in the material. Such as shear failure of pin , crushing failure of pin ,crushing failure of pin in coupler , bending failure of pin . After finding the various possible failure and elasticity of the material. Their analysis is done in the using of catia software and they concluded that due to better flexible material is used for pin is plastic material i.e. steel. That material also prohibited to rust and corrosion and there is low coefficient of friction between the knuckle , pin and coupler body [1].
1.1 COMPONENTS OF KNUCKLE JOINT A knuckle joint can be following these four 2) Single eye end 3) Double eye end 4) Knuckle pin 5) Collar pin 6) Taper pin / Split pin
components fig. failure of knuckle pin
1.2 FAILURE OF KNUCKLE JOINT A knuckle joint can be failed on the following three modes are: 1) Shear failure of pin (single shear) 2) Crushing of pin against rod 3) Tensile failure of flat end bar

Rangari et. Al.: They analyzed the knuckle joint used in Mahindra 575 DL . their views on knuckle joint is failure in various condition like single eye , double eye or fork pin .He hinds the mainly failure in the knuckle pin which is bending during the carry heavy loads. So they have to change the pin again and again .In engineering field we have to reduce the cause of failure of pin to using various methodology. they used to theoretical and F.E.A to determine the cause of failure also they using the different material for designing the knuckle pin like grey cast iron, steel and titanium at equal loading condition they found that there is equivalent stress , shear stress and total deformation is maximum stresses on same loading condition[2].
