PowerPoint presentation of connecting rod

1. ABSTRACT
 Connecting rod is the one of the important components
of the wall engine assembly as it act as mediator between
piston assembly and crankshaft.
 It converting the reciprocating motion of the piston to
rotary motion of the crank. Also it faces a lot of tensile
and compressive loads during its life time.
 Generally connecting rod are manufactured using carbon
steel and in recent days aluminium alloys are finding its
application in connecting rod

2.  In this work connecting rod is replaced by aluminium
based composite material reinforced with silicon
carbide. It also describes the modelling and analysis
of connecting rod.
 Solid work modelling is a software used to generate
3-D solid model of connecting rod. Ansys software is
used to analyse the connecting rod.
 The main aim of the project is to analyse the stress,
strain, deformation of connecting rod by varying
material with same geometry.

5. INTRODUCTION
 A connecting rod is the link between the reciprocating
piston and rotating crank shaft. Small end of the
connecting rod is connected to the piston by means of
gudegeon pin.
 The big end of the connecting rod is connected to the
crank shaft. The combination of the axial and bending
stress act on the rod in operation.
 The axial stresses are product due to the cylinder gas
pressure and inertia force arising on the account of
reciprocating motion.

6.  To provide the maximum rigidity with minimum
weight to cross section of the connecting rod is made
as I-section and end of the rod is solid eye or split
eye, the end holding the piston.
 In some connecting rod hole is drilled between two
end for carrying lubricating oil from big end to the
small end for lubrication of piston and piston pin
axial stresses.
 There for in order to study strain intensity, stress
concentration and deformation in the crank end of the
connecting rod, based on the working parameter and
vehicle choosen the design parameter.

7. METHODOLOGY
 Synthesis : Try to develop different alternatives.
 Conceptualization : Draw sketches in exact scale for
different alternatives.
 Analysis : Analysis different alternatives with respect to
strength , stress etc.
 Selection : Select the best alternatives.
 Basic engineering: Prepare layout in exact scale,
calculate strength of component and select proper cost
effective material.
 Detail design : Prepare detail engineering drawing for
each component.

8. CASTING METHOD
Stir Casting
Stir Casting is an economical process for the fabrication
of the aluminium matrix composites. There are many parameters
in the process which affect the final microstructure and
mechanical properties of the composites.

22. Conclusion
 The present material used for connecting rod Al6061 is
high deformation when compare to Al6061+SiC. So
Al6061+SiC have low deformation the result is
increasing the life time of the connecting rod.
 As compared to Aluminium the composite material
having high von mises stress , so it has high strength.
 The composite material having high hardness because
of low von misses strain.
 Charpy and Izod test are performed for obtaining the
strength of the material. From the result we concluded
that Al6061+SiC has higher strength than the Al6061.
