2. INTRODUCTION
• Clutch is a mechanical device located between a vehicle
engine and its transmission and provides mechanical coupling
between the engine and transmission input shaft. Clutch
system comprise of flywheel, clutch disc plate and friction
material, pressure plate, clutch cover, diaphragm spring and
the linkage necessary to operate the clutch.
• The clutch engages the transmission gradually by allowing a
certain amount of slippage between the flywheel and the
transmission input shaft. However, the slipping mechanism of
the clutch generates heat energy due to friction between the
clutch disc and the flywheel.
• Clutch works on the principle of friction. When two friction
surfaces are brought in contact with each other and pressed
they are united due to the friction between them.

3. • The friction between the two surfaces depends upon the area
of the surfaces, pressure applied on them and co-efficient of
friction of the surface material. The two surfaces can be
separated and brought into contact when required.
• One surface is considered as a driving member the other as a
driven member. The driving member is kept rotating, when the
driven member is brought in contact with the driving member
it also rotates. When the driven member is separated from the
driving member it does not rotate. This is the principle on
which the clutch operates.

4. OBJECTIVE
• To carry out the dynamic analysis of friction plate using
different friction materials.
• Using sintered metals we can reduce the wear of friction plate.
• The stress and deformation is to be obtain for the different
materials and compare their results.

2 Design and analysis of clutch
using sintered iron as a friction
material
Mamta G. Pawar, Monarch K.
Warambhe and Gautam R. Jodh
In this project after designing of clutch
disc, the analysis is done by varying the
friction material & following
conclusion is drawn. The analysis is
done for worn out friction disc. The
stresses using Kevlar as a friction
material & sintered iron is near about
same. Torque transmission capacity of
sintered-iron friction material is 350 to
400N which is more than Kevlar. Total
deformation in Kevlar material is less
than sintered-iron friction material.
Sintered-iron material can sustain
higher temperature. By applying the
maximum force i.e, 220 N of the
friction plate of single plate clutch, after
analytical calculations & software
analysis the following observations can
be obtained.

In this project, a 3D model of multi-
plate clutch and its assembly has been
done using Pro-E software packages.
Structural analysis on clutch plate has
been carried out using ANSYS
workbench for copper, cork and SA92
as friction lining materials. Ultimately,
from this analysis it can be concluded
that, on the strength basis, SA92 is
more suitable and quite better friction

4 Dynamic analysis of crack in
composite material
K.Praveen, rakesh jalla
In this paper, to investigate how a
crack propagates and grows in a clutch.
The finite element program ANSYS is
used to simulate crack growth and to
compute the stresses and the stress-
intensity factor. By observing the
analysis results, the stress values are
more for composite materials and when
the crack is started the composite
materials, stress values increases more
than the condition of no crack so the
composite materials fails faster once the
crack propagates.
So we can conclude that if the crack
propagates in the composite materials,
they tend to fail faster than aluminum
alloys thereby reducing their life. So
care should be taken for composite
materials not to get the crack.

In engineering application is largely dependent on the
development of higher density materials and
improved mechanical properties. An experimental
investigation have been undertaken in order to
understand the variation of density with respect to the
variation of process parameters such as compaction
load, sinter temperature and sintering time.
In this project, a detail microstructure analysis has
been made which confirms that the density of the P/M
product considerably increases with the increase in
compaction load, sintering temperature and sintering
time. The results obtained have been analyzed
through the response surface model.

8 THE EFFECT OF BORON LIQUID PHASE
SINTERING ON PROPERTIES OF ni-,
mo-, cr- ALLOYED STURUCTURAL
STEELS
M. Selecka, A. Salak and H.
Danninger
In this project, they concluded that Boron is
evaluated as the best sintering enhancing element
in terms of identifying the iron-based materials
by formation the liquid phase. The influence of
boron addition (up to 0.6%) on the density,
microstructure formation and the strength of the
different pre-alloyed powders. Micro-structural
analysis showed an interaction of boron with
matrix alloying elements. The formation of
borides caused the increase of micro-hardness
and hardness values of matrix. The higher
density and micro-hardness expressed in higher
strength of materials. The material systems based
on iron, Ni-, Mo- and Cr- pre-alloyed powders
with boron addition up to 0.6% after sintering at
1200 ◦C for 60 min in hydrogen were
investigated.
A positive effect of boron liquid phase sintering
on the properties of Ni-, Mo- and Cr-alloyed
material systems was demonstrated.

9 Hoganas “(SINTERED IRON BASED
MATERIALS)”
Hoganas has developed a variety of
materials containing Mo in combination
with Ni or Cu, or both Ni and Cu, which
have proven very successful in the
production of structural parts for high-
strength and high-accuracy applications.
Some of these materials are homogenous
alloys with the trade-name Astaloy, but most
of them are partially pre-alloyed non-
segregable powder mixes with the trade-
name Distaloy.
Mixed with appropriate amounts of
graphite, Astaloy- and Distaloy-materials,
yield high strength properties, show good
dimensional stability during sintering, and
respond very well to subsequent heat-
treatment.

10 Experimental
characterization of frictional
behaviour of clutch facings
using Pin-on-disk machine
M.Bezzazi, A. Khamlichi
During the clutch engagement, sliding contact
occurs between the pair of clutch facings mounted
on the friction disk and the counter faces
belonging to the flywheel and the pressure plate.
The transmitted torque is proportional to the
overall coefficient of friction which depends
essentially on temperature, normal pressure load
and relative sliding velocity. In this work,
performance of the friction coefficient is
investigated experimentally. Samples of a
commercial clutch facings material have been
tested using a Pin-on-disk apparatus. When the
previous three parameters are preset constant, this
machine provides automatic acquisition of friction
coefficient and wear measurements. The obtained
results are compared with the classical SAE J661a
standard test.

PROBLEM DEFINITION

17. • The problems with a slipping clutch are that the friction material’s
coefficient of friction is affected by heat. As temperature goes up the
coefficient of friction goes down, and the total clutch capacity decreases.
Heat reduces friction, which increases slippage, which increases heat the
cycle becomes self-limiting when the torque capacity of the clutch drops
to zero.

19. • On the flip side, organic material does have less heat
capacity than most other common lining material and it wears
fast than some other. The heat created by a Kevlar disc
slipping against flywheel and will burn the flywheel.
• The clutch engages the transmission gradually by
allowing a certain amount of slippage between the flywheel
and the transmission input shaft. However, the slipping
mechanism of the clutch generates heat energy due to friction
between the clutch disc and the flywheel.

20. • At high sliding velocity, excessive frictional heat is
generated which lead to high temperature rise at the
clutch disc surface, and this causes thermo-mechanical
problems such as thermal deformations and thermo-
elastic instability which can lead to thermal cracking,
wear and other mode of failure of the clutch disc
component.
• By using Iron - Copper - Nickel - Molybdenum –
Carbon, Hoganas has developed a variety of materials
containing Mo in combination with Ni or Cu, or both Ni
and Cu, which have proven very successful in the
production of structural parts for high-strength and high-
accuracy applications. Such as Distaloy SA, Distaloy AB,
Distaloy SE, Distaloy AE.
• Dynamic analysis is carrying out to determine the
stress and deformation for different materials.

22. Selection of friction materials
• Distaloy SA is based on the sponge iron grade SC100.26 to
which 1.75%Ni, 1.5%Cu and 0.5%Mo have been diffusion-
bonded. Being based on sponge iron powder, this material has
high green-strength. Mixed with appropriate amounts of
graphite it yields high strength after sintering and responds
well to subsequent heat-treatment.
• Distaloy AB has the same chemical composition as Distaloy
SA but is based on the atomized iron powder grade
ASC100.29. Being based on atomized iron powder, it has high
compressibility. Mixed with appropriate amounts of graphite it
yields high strength after sintering and responds well to
subsequent heat-treatment.

23. CONT..
• Distaloy SE is based on the sponge iron grade SC100.26 to
which 4%Ni, 1.5%Cu and 0.5%Mo have been diffusion-
bonded. Being based on sponge iron powder, it has high green-
strength. Mixed with appropriate amounts of graphite it yields
high strength after sintering and responds very well to
subsequent heat-treatment.
• Distaloy AE has the same chemical composition as Distaloy
SE but is based on the atomized iron powder grade
ASC100.29. Being based on atomized iron powder, it has high
compressibility. Mixed with appropriate amounts of graphite it
yields high strength after sintering and responds very well to
subsequent heat-treatment.

24. • Properties of distaloy-materials

25. Modeling of friction plate
• Solid modeling of friction plate is to be model by using
catia v5 software TATA SFC-407 specification.
Dynamic analysis
• The design of products that need to survive impacts or short-
duration high-pressure loadings can be greatly improved with
the use of ANSYS explicit dynamic solutions.
• By explicit dynamic analysis stress and deformation is to be
obtained by different materials and compare with the results.
