Modeling and Analysis of Knuckle Joint used in Tractor
0 likes270 views
This document summarizes research on modeling and analyzing the knuckle joint used to connect tractors and trailers. The knuckle joint consists of eye forks and a pin and is subjected to tensile and compressive forces during vehicle motion. Previous studies analyzed knuckle joints using finite element analysis in ANSYS and modeling in CATIA to determine stress levels and potential failure modes like pin shear, pin crushing, or bar tensile failure. The current study models and analyzes the knuckle pin using CATIA and ANSYS to calculate stresses under 50kN of load. Preliminary results found stresses on the pin increased with load but could be reduced by increasing the pin diameter.

Abstract - Tractor and trailer is a very useful component in
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. Intheknuckle
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 stressesinpingoingto be
study by using catia V5 and finite element method to be used
in analysis.

1.INTRODUCTION
Knuckle joint is a joint which is used to connect two rods
under the tensile load. It is a type of hingedjoint.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.
1.1 COMPONENTS OF KNUCKLE JOINT
A knuckle joint can be following these four components
2) Single eye end
3) Double eye end
4) Knuckle pin
5) Collar pin
6) Taper pin / Split 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
2. LITRATURE REVIEW:
Dharpure and mate: They are working in the study and
analysis of the failurecondition inknucklejointwhichisused
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 overithoweverdue
to the manufactureof the knuckle and theircauseoffailureof
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
failureand 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 materialalso prohibited to rust and corrosionand
there is low coefficient of friction between the knuckle , pin
and coupler body [1].

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 theoreticaland F.E.A to determinethecauseoffailure
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].](https://image.slidesharecdn.com/irjet-v4i7495-170911072322/85/Modeling-and-Analysis-of-Knuckle-Joint-used-in-Tractor-1-320.jpg)

Fig: design of knuckle joint (3D)
Bhasha and Vanka :In this paper he had been using the
finite element method to perform the modeling and analysis
of the knuckle joint. For 3D model is modeling in catia
software and analysis is done on ANSIS soft ware. He applied
the F.E.A method for stainless steel , grey cast iron , and
Teflon material.after that they check the various failure
modes in different loading condition and they designed the
knuckle for 50KN axial load in theoretical calculation and
stress produced in Teflon material is very close to stainless
steel and grey cast iron [3].
Patil et. Al.: In this paper they calculate the knuckle joint
stress with using the analyticalmethod.Inthesepeoplestudy
about the modeling and analysis of a knuckle joint using
F.E.M. he also define the failure modes of knuckle joint dueto
various stresses are develop for reducing the stress they
using the F.E.M in their research paper. first of all they draw
the geometric model in catia V5 and after that analytical
simulation is to be proceed in the several material choose for
manufacturing of knuckle joint such cast iron . they finalized
the structural steel to be used for modeling and analysis. In
catia V5 concluded that generating the meshes and given the
second ordertetrahedronmeshingtotalelementcontendand
total nodes contained , after completing the meshing they
simulated in the ANSYS software and we obtained stress are
very less than the yield stress of steel [4].
Shinde and kalita : In this paper said that about the
knuckle joint which is used in the tractor trollry. He said that
tractor acceleration is main reason for force acting on the
knuckle joint, they consider the newton second law for case
study their first step has to be modeling and analyzing
machine component and draw on the solid model.They seen
that accuracy of solid model is directly depend on the
obtained result from ANSYS. It is based on the actually
dimension are calculated for a traile [5].
Herakal et. Al.: They study the knuckle joint using the finite
element method .Theknuckle joint is modeled in catia V5 .he
study about the geometric modelanddrawitandafterthatis
meshing in ANSYS and the result says that under loading
condition igher stress developed in the fork and the less
stress developed in eye and applied stress in the fork is more
higher than allowable stress then it is not able to design the
component as the safe point of view [6].
3. CONCLUSIONS
After studying the knuckle joint which is used in tractor and
trolley , modeling and analysis on knuckle pin as following:
According to our theoretical study , calculation and F.E.A
have to around similar results on 50 mm diameter at 60 KN.
We also find the when increase the stress on pin can be
bending but we increase the pin diameter. it will wear
maximum stress on that force.
