Engines are power source to the automobiles. Engine that converts combustion of fuel gas
energy in to some mechanical power . The main components of engines are piston, cylinder
block, cylinder head, crank shaft, connecting rod, cam shaft, and there are other components. In
this project we are studying about the structural analysis on piston .Piston that transfer the
combustive gases power to the connecting rod. To improve the efficiency of the engine there is a
need to study about the piston. Pistons that are usually made up with alloy steels that shows the
grate resistant against thermal loads and structural loads. Alloy steel pistons are light weight in
nature and they can with stand against the high compressive and tensile loads. In the project we
design a piston by using solid works software 2016 and we did the structural load analysis and
thermal analysis on piston by using solid works simulation software.

Piston is the part of engine which converts heat and pressure energy liberated by fuel combustion into
mechanical works. Engine piston is the most complex component among the automotives. Weight
reduction has been gaining importance in automobile field because reducing in weight decreases load
on the engine and thus increasing efficiency of the engine. As we all Know that Piston is made of
Aluminum Alloy Such that its weight is less. The automobile industry has shown increased interest in
replacingthe Pistonwiththe material havinghighstrengthtoweightratio.
Therefore the objective of this project is to present a general study on the performance comparison of
composite Piston and Aluminum Alloy Piston. Dimensions and specifications used in modeling are
collectedfromthe actual PistonofHero-HondaSplendorBike.The Pistonismodeling insolidWorks.

A piston is a disc which reciprocates within a cylinder. It is either moved by the fluid or it moves the fluid
which enters the cylinder. The main function of the piston of an IC engine is to receive the impulse from
the expanding gas and to transmit the energy to the crankshaft through the connecting rod. The piston
must also disperse a large amount of heat from the combustion chamber to the cylinder walls. Cast iron,
Aluminium Alloy and Cast Steel etc. are the common materials used for piston of an Internal Combustion
Engine. In this project here we were taken steel is an existing material and aluminium is another
material.The material used is Aluminium Alloy and steel are used to determine the good material for
manufacture of the piston here we analyze the two materials with the help of fem. In order to get better
results here we are adding 0.4mm ceramic layer for both material and analysed with same boundary
conditions. And calculating results like deformation, stress, safety factor. And total temperature and
heat flux also. The main objective piston is investigate and analyze the thermal stress distribution of
piston at the real engine condition during combustion process, in this process we applied temperature
and convection as boundary conditions and we determining total temperature on the body, total heat
flux values.

A piston is a component of reciprocating engines, reciprocating pumps, compressors and pneumatic
cylinders, among other similar mechanisms. It is the moving component that is contained by a cylinder
and is made gas-tight by piston rings. The piston transforms the energy of the expanding gasses into
mechanical energy. The piston rides in the cylinder liner or sleeve. Pistons are commonly made of
aluminum or cast iron alloys The present project to designed a piston for 1300cc diesel engine car and
taken 3 different profile rings .A 2D drawing is created from the calculations. The piston and piston rings
are modeled using Pro/Engineer software, The stress and displacement are analyzed for the piston and
piston rings by applying pressure on it in Structural analysis. By observing the analysis results, we can
decide whether our designed piston is safe or not under applied load conditions. The thermal flux,
thermal temperature distribution is analyzed by applying temperatures on the piston surface in Thermal
analysis. The structural and thermal analysis were also done on the piston and piston rings model using
Cast iron, Aluminum Alloy A360 and Zamak. By comparing both the material analysis and decided which
material is better for manufacturing of Piston and piston rings. Structural and Thermal analysiswere also
performedinANSYSsoftware.

In this paper, the wok is carried out to measure the stress and temperature distribution on the top
surface of the piston. In I.C. Engine piston is most complex and important part therefore for smooth
running of vehicle piston should be in proper working condition. Pistons fail mainly due to mechanical
stresses and thermal stresses. Analysis of piston is done with boundary conditions, which includes
pressure on piston head during working condition and uneven temperature distribution from piston
head to skirt. The analysis predicts that due to temperature whether the top surface of the piston may
be damaged or broken during the operating conditions, because damaged or broken parts are so
expensive to replace and generally are not easily available. The CAD model is created using CATIA V5
tool. CAD model is imported into the Hyper Mesh for geometry cleaning and meshing purpose. The FEA
is performed by using RADIOSS. The topology optimization of the model is done using OptiStruct module
of HyperWorkssoftware.

The Braking system is an important aspect of the vehicle. Disc brake system comprises of
disc placed between two pads. Hydraulic system helps these pads to come in contact with the
disc to slow down the rotation of wheel and finally to stop the vehicle. The disc brakes are of two
types a solid type and vented, vented disc have fins to allow air to pass through.
The project aims to study and analyze the disc in the disc brake system with changing
parameters like material and area of contact of pad with disc. A non vented disc brake is
designed and results are studied.
The CAD models are built in CATIA The model is imported into HYPERMESH
software and analysis is done using RADIOSS module of Hyper mesh 11 software by using
calculated values as input and finally the best material for disc brake is found among the
selected materials.

ABSTRACT: Engine pistons are one of the most complex components among all automotive or other
industry field components. The engine can be called the heart of a car and the piston may be considered
the most important part of an engine. There are lots of research works proposing, for engine pistons,
new geometries, materials and manufacturing techniques, and this evolution has undergone with a
continuous improvement over the last decades and required thorough examination of the smallest
details. Notwithstanding all these studies, there are a huge number of damaged pistons. Damage
mechanisms have different origins and are mainly wear, temperature, and fatigue related. Among the
fatigue damages, thermal fatigue and mechanical fatigue, either at room or at high temperature, play a
prominent role. In this present work a piston is designed using CATIA V5R20 software. Complete design
is imported to ANSYS 14.5 software then analysis is performed. Aluminium alloy have been selected for
structural and thermal analysis of piston. An analysis of thermal stress and damages due to application
of pressure is presented and analyzed in this work. Results are shown and a comparison is made to find
the most suiteddesign.
