ANALYSIS OF HEAT LOSSES IN YTTRIA ZIRCONIA, CHROMIUM
OXIDE & TUNGSTEN CARBIDE COATED ON PISTON CROWN IN
SI ENGINE
ABSTRACT
The demand for increasing the efficiency of an
internal combustion engine has been going on ever since the
invention of this reliable workhorse of the automotive world.
Recently, researches have been focused on achieving this goal by
reducing energy lost to the coolant during the power stroke of the
cycle. Yttria Zirconia, Tungsten carbide and Chromium oxide
coatings have a significant effect in the reduction of wear and
abrasion failure in reciprocating and rotary engines for
transportation and stationary power. As operating temperatures are
pushed higher to improve efficiency in these engines, the
wear/abrasion problem becomes more challenging because
lubrication in the high temperature locations becomes increasingly
problematic. These coatings also have applications as thermal
barriers to improve the efficiency of the engines, by reducing energy
loss and cooling requirements. The main aim of this project is to
evaluate the effects of ceramic coating on petrol engines effective
efficiency at different engine loads and speeds. These coated piston
have low thermal conductivity so thermal barrier leads to the
increase in efficiency and performance. The results showed a
reduction in heat loss to the coolant. The steady state thermal
analysis is to be done over the uncoated and ceramic coated piston
and the distribution of heat over the crown is to be studied.

The Automobile Industry has shown increase interest for
replacement of steel leaf spring with that of composite leaf
spring, since the composite material has high strength to
weight ratio, good corrosion resistance and tailor-able
properties. The paper describes static analysis of steel leaf
spring and laminated composite Multi leaf spring. The
objective is to compare the load carrying capacity, stiffness
and weight savings of composite leaf spring with that of steel

CAD MODELING AND STATIC STRUCURAL ANALYSIS IN
MATERIALS OF ALLOY WHEEL RIM FOR TWO WHEELER
ABSTRACT
The project is to design the motorcycle alloy wheel using the
PRO-E and Analyzed with the ANSYS. Ansys is a tool used for the
evaluation of systems and structures. It is needed to analyze
complex structures, whereas very simple ones. There are three
processes involved which are preprocessing, analysis and
visualization. The PRO-E is used because specialized modules, so
phisticated shape modeling, can be designed for large teams and
easy to use. There was two way analyzed which were analysis the
rim statically in a straight road and cornering. The chosen material
was an Aluminum alloy, magnesium alloy, titanium alloy. The
aluminum alloy is better to the conventional steel wheels in
strength and durability. It has excellent wear resistance,
anticorrosion properties and longer service life as estimated by the
stress frequency distribution. The analysis is done with the
maximum load can be applied on rim. The rear wheel and front
wheel have their own maximum load that can be supported. It is
because the rear wheel is carrying a person while the front wheel
only the weight of the bike like mark guard and motorcycle handle
that assembles to it. It was found that the stress of the analysis is
still in the range of the yield strength of Aluminum alloy. The
Displacement is at the low value. This design is still in the safe
condition. The project is to sharpen skill using CAD (PRO-E) and
CAE (ANSYS), practice to be creative in design the bike alloy wheel
and analyze the result of ANSYS. It is recommended if analyze with
different material and can be manufactured for further study.

DESIGN OF WIND TURBINEBLADE BY USING COMPOSITE
MATERIAL
ABSTRACT
The wind turbine blade is a very important part of the rotor.
Extraction of energy from wind depends on the design of the blade.
The advancement of fibre composite materials has provided the best
solutions to overcome inefficiencies caused by traditional materials
used in wind turbine construction.
At present, the majority of wind turbine blades are
constructed with glass fibre reinforced plastic (GFRP). The use of
composite materials eventually have solved some of the problems
associated with efficient operation of horizontal axis wind turbines
(HAWTs) such as gravitational forces due to weight but there are
other unresolved problems such as long term material property
degradation, local shape deformation of the profile of the wind
turbine blades etc.
This project aims to address the adverse structural response
of the blade profile with the variation of operational parameters
such as wind velocity and material properties on blade’s
performances. A parametric blade model utilising the ANSYS finite
element program has been developed to efficiently predict the
deflection of the blade.

modal and the distortion and stress status of the crank throw. The
maximum deformation, maximum stress point and dangerous areas
are found by the stress analysis of crank throw. The relationship
between the frequency and the vibration modal is explained by the
modal analysis of crankshaft. The results would provide a valuable
theoretical foundation for the optimization and improvement of
engine design.

DESIGN AND COMPARATIVE THERMAL ANALYSIS DISK BRAKE
FOR FOUR WHEELER
ABSTRACT
The disc brake is a device for slowing or stopping the rotation of a
wheel. A brake disc (or rotor ) usually made of cast iron or ceramic
composites (including carbon, Kevlar and silica), is connected to the
wheel and/or the axle. To stop the wheel, friction material in the
form of brake pads (mounted on a device called a brake caliper) is
forced mechanically, hydraulically, pneumatically or
electromagnetically against both sides of the disc. Friction causes
the disc and attached wheel to slow or stop. Most modern cars have
disc brakes on the front wheels, and some have disc brakes on all
four wheels. This is the part of the brake system that does the
actual work of stopping the car. In today’s growing automotive
market the competition for better performance vehicle in growing
enormously.
The thermal properties of disc in disc brake are an important
factor. There are many types of disc brake. Each one shows
different braking performance in braking. So the factors influencing
the performance should be found out and a better new or modified
disc brake should be created
The defects in disc brake are enormous. In order to rectify all these
defects a new modified rotor is created. The model of disc drake as
per given specification of FORD vehicle using PRO-E W/F 5.0
software and the analysis is done in ANSYS 12.0 software. All the
analysis report is included in this report

ANALYSIS OF HEAT TRANSFER AND EXPERIMENTAL
INVESTIGATION OF AIR COMPRESSOR CYLINDER BY
MODIFYING EXTERNAL FINS
ABSTRACT
Most air compressors are either reciprocating
piston type or rotary vane or rotary screw. Centrifugal compressors
are common in very large applications such as supply a high-
pressure clean air to fill gas cylinders, supply a large amount of
moderate pressure air to power pneumatic tools.
In air compressor heat can be generated by two ways, heat
produced by friction as well as by due to compressing of air at high
pressure .So this heat will transfer to atmosphere by fins. As
engineers we are primarily interested in knowing the extent to
which particular extended surfaces or fin arrangements could
improve heat transfer from a surface to the surrounding fluid.
To determine the heat transfer rate associated with a fin, we
must first obtain the temperature distribution along the fin. But
normally annular fin is one that is circumferentially attached to a
cylinder, and its cross section varies with radius from the centerline
of the cylinder. In our project we altered geometrical shapes of fins
for experiment process and select most effective cooling fin.
Finite element method (FEM) is important numerical
techniques used in engineering analyses. Usually elements are sub-
divided uniformly in FEM (conventional FEM, CFEM) to obtain
temperature distribution behavior in a fin or plate. In this project,
non-uniform sub-elements are considered for FEM solution to
reduce the computational complexity. Then this FEM is applied for
the solution of one-dimensional heat transfer problem in a
rectangular thin fin.

the various types of cooling Method. Using Neutral file format the model was
imported into HYPERMESH. Here the solid model was converted into Finite
Element model. Boundary conditions such as maximum temperature of the
cylinder, convective heat transfer coefficient, ambient temperature and material
properties such as thermal conductivity of the material are used as set of
parameters for the program. Heat flux and temperature profiles were used as
measure of efficiency.
ANALYSIS OF CHASSIS CROSS SECTION “C” and “BOX” channel
with LOADING CONDITION
ABSTRACT

The present scenario in automotive industry is an sum in demand of trucks not
only on the cost and heaviness aspects but too on improved total vehicle features
and overall work performance. The chassis plays an important role in the design
of any truck.
Truck chassis forms the structural backbone of a commercial vehicle. The main
function of the truck chassis is to support the components and payload placed
upon it. When the truck travels along the road, the chassis is subjected to
vibration induced by road roughness and excitation by vibrating components
mounted on it. The responses of the truck chassis which include the stress
distribution and displacement under various loading condition are also observed.
The mode shape results determine the suitable mounting locations of
components like engine and suspension system. Some modifications are also
suggested to reduce the vibration and to improve the strength of the truck
chassis.
The chassis design in general is a complex methodology and to reach at a solution
which yields a good performance is a tedious task. Since the chassis has a complex
geometry and loading patterns, there is no well defined analytical procedure to
analyze the chassis. So the numerical route of analysis is adopted, in which Finite
Element Technique is most widely used route.
The main objective of this work is to assess static characteristics of a truck chassis
under different load conditions. Geometric modeling of the various components
of chassis has been carried out in part mode as 3-D models using PRO-E W/F. The
properties, viz. crossectional area, beam height, area moments of inertia of these
3-D modeled parts are estimated in PRO-E W/F. These properties have been used
as input while performing the Finite Element Analysis using ANSYS work bench.

Fiber Materials

ABSTRACT
Chassis is the foremost component of an automobile that acts as the
frame to support the vehicle body. Hence the frame ought to be very rigid and
robust enough to resist shocks vibrations and stresses acting on a moving
vehicle. Steel in its numerous forms is commonly used material for producing
chassis and overtime alumimium has acquired its use. However, in this study
traditional materials are replaced with ultra light weight carbon fiber materials.
High strength and low weight of carbon fibers makes it ideal for manufacturing
automotive chassis. This paper depicts the modal and static structural analysis
of TATA 407 fire truck chassis frame for steel as well as carbon fibers. From
the analyzed results, stress, strain and total deformation values were compared
for both the materials. Since it is easy to analyze structural systems by finite
element method, the chassis is modified using PRO-E and the Finite Element
Analysis is performed on ANSYS workbench
Modeling and Analysis of wheel rim comparative analysis with shape
optimization of for four wheeler

Abstract
Trucks have been basic backbone of the world's workforce for decades. They're big,
powerful, and can really get you through the roughest of terrains. But a truck can't do its job
without properly functioning wheels. AUTOMOTIVE rims need to be replaced if they're bent or
cracked for the sake of your truck's life - and sometimes just for an upgrade. Knowing your truck
rim options will greatly assist you in this process.
Most steel truck rims are created in the same way. It starts with a hard cast hub, with 4, 5 or even
6 holes for the bolts. A spun steel rim is then secured around this with a series of welds. The rim
is properly balanced and then given a smooth finish. Although some steel rims are available in
silver and chrome, most of those finishes are saved for alloy wheels.
Truck wheels need to be durable and able to carry around weight. You won't find many spoke
designs with these rims. They're usually as solid as possible. But that doesn't mean your options
aren't varied when looking for replacements. The most important thing to remember is to
purchase the same size rims you're replacing unless you're also planning on vehicle
modifications.
Lighter wheels can improve handling by reducing unstrung mass , allowing suspension to follow
the terrain more closely and thus improve grip, however not all alloy wheels are lighter than their
steel equivalents. Reduction in overall vehicle mass can also help to reduce fuel consumption .

BUCKLING AND STRUCTURAL ANALYSIS OF SHOCK ABSORBER USING ANSYS
Abstract
A suspension system or shock absorber is a mechanical device designed to smooth out or damp
shock impulse, and dissipate kinetic energy. The shock absorbers duty is to absorb or dissipate
energy. In a vehicle, it reduces the effect of traveling over rough ground, leading to improved
ride quality, and increase in comfort due to substantially reduced amplitude of disturbances.
When a vehicle is traveling on a level road and the wheels strike a bump, the spring is
compressed quickly. The compressed spring will attempt to return to its normal loaded length
and, in so doing, will rebound past its normal height, causing the body to be lifted. The weight of
the vehicle will then push the spring down below its normal loaded height. This, in turn, causes
the spring to rebound again. This bouncing process is repeated over and over, a little less each
time, until the up-and-down movement finally stops. If bouncing is allowed to go uncontrolled, it
will not only cause an uncomfortable ride but will make handling of the vehicle very difficult.
The design of spring in suspension system is very important.
In this project a shock absorber is designed and a 3D model is created using Pro/Engineer.
Buckling analysis and Structural analysis is done on the shock absorber by varying material for
spring, Structural Steel and Titanium alloy. The analysis is done by considering loads, bike with
2 persons. Structural analysis is done to validate the strength and displacements for different
materials. Comparison is done for two materials to verify best material for spring in Shock
absorber. Modeling is done in Pro/ENGINEER and analysis is done in ANSYS.

ANALYSIS OIL FLOW AND VELOCITY ANALYSIS OF OIL PUMPING IN A
RECIPROCATING COMPRESSOR (CFD)
ABSTRACT
The immediate provision of lubricant oil to the radial and thrust bearings and to
the piston-cylinder gap in reciprocating refrigeration compressors is a crucial
reliability issue following compressor start-up. The aim of this paper is to present
a hydrodynamic analysis of the lubricant oil pumping system of a reciprocating
compressor using Computational Fluid Dynamics (CFD). In the present system, oil
is pumped from the sump through a reed-type centrifugal pump located at the
bottom end of the shaft. The oil flows initially as a climbing film on the internal
surface of the shaft before it is directed to the external surface where it flows
along a helix channel carved on the shaft wall. The model was implemented on
the commercial package Fluent using the Volume of Fluid (VOF) Method to
resolve the free-surface oil flow. Parameters regarding the oil behavior during
start-up, such as the time required to reach steady-state operation and the
associated oil mass flow rate are explored in the manuscript.

Design and Analysis of Bell Mouth Inlet using CFD
ABSTRACT
The design and analysis of bell mouth inlet deals with aerodynamic study of
different inlet configurations. A bell-mouth inlet duct is extremely efficient, and is
used where there is little ram pressure available to force the air into the engine.
Bell-mouth ducts are used in engine test cells and on engines installed in
helicopters.The bellmouth cross sectional area is normally double that of the duct
area, so that the air velocity entering the bellmouth is low (to reduce noise,
turbulence and pressure drop), and gradually increases to the normal design
velocity of the ductwork.
Different designs are compared with different ambient conditions using CFD
analysis using Fluent software. The meshing is done as 2D model using Gambit
software. The overall performance of the final configuration is analyzed using
CFD analysis.

Abstract
Good fuel injector geometry is always in need for an efficient scramjet operation.
Injecting fuel into a supersonic flow is one of the challenging tasks during the
design of scramjet. Injection into a supersonic flow will result in total pressure loss
and increase in total drag of scramjet. A supersonic intake and the combustor
geometry for a typical scramjet engine without diffuser is designed and analysed.
A higher contraction ratio fixed geometry intake scramjet has been designed using
in viscid calculations and computational fluid dynamics. For the designed
geometry, the wall fuel injector geometry is designed. For the designed scramjet
geometry, numerical studies have been undertaken to study the fuel injection angle.

CFD ANALYSIS OF DRAG REDUCTION WIND ANGLE OPTIMIZATION
ON CARS
ABSTRACT
Recent spikes in fuel prices and concern regarding greenhouse gas emissions,
automotive design engineers are faced with the immediate task of introducing more
efficient aerodynamic designs vehicles. The aerodynamic drags of a road vehicle
are responsible for a large part of the vehicle’s fuel consumption and contribute up
to 50% of the total vehicle fuel consumption at highway speeds. One of the main
causes of aerodynamic drag on cars is separation of flow near the vehicles rear end
and front wind screen angle. Reduction of wind angle causes a reduction of
pressure rise in front of vehicle. And also reduces the turbulence intensity, and
pressure drop behind the vehicle. In this analysis, car model is analyzed with three
wind angle 60, 45 and 30 degree. Pressure, velocity and turbulence contours are
measured with different angle condition.
