Stress Analysis of I.C.Engine Connecting Rod by FEM and PhotoelasticityIOSR Journals
Abstract: The automobile engine connecting rod is a high volume production critical component. Every vehicle
that uses an internal combustion engine requires at least one connecting rod .From the viewpoint of
functionality, connecting rods must have the highest possible rigidity at the lowest weight. The major stress
induced in the connecting rod is a combination of axial and bending stresses in operation. The axial stresses are
produced due to cylinder gas pressure (compressive only) and the inertia force arising in account of
reciprocating action (both tensile as well as compressive), where as bending stresses are caused due to the
centrifugal effects. The result of which is, the maximum stresses are developed at the fillet section of the big and
the small end.Hence, the paper deals with the stress analysis of connecting rod by Finite Element Method using
Pro/E Wildfire 4.0 and ANSYS WORKBENCH 11.0 software. The comparison and verification of the results
obtained in FEA is done experimentally by the method of Photo elasticity(Optical Method). The method of
Photoelasticity includes the casting of Photoelastic sheet using Resin AY103 and Hardner HY951, preparation
of the model from Photoelastic sheet calibration of the sheet to determine material fringe value.

The IC engine has seen numerous revolutionary and e volutionary modifications in technology and design over the past few decades. The sole motto behind the modifications wa s to increase the overall efficiency of the IC Engi ne including volumetric and thermal efficiency. Recently few benchmarking techn ologies like the CRDI,MPFI,HCCI,etc. in the Otto cycle and Diesel cycle engines have created an enormous revolution in the automobile industry. In spite of these technologica l and design advances,the efficiencies are not being more than a particular l imit. However,the concept of split cycle engines has dra stically increased the overall performance in all respect. The split cycle concept basically separates the fou r strokes of the conventional cycle. The Scuderi engine one of the best-in-class engine desi gns based on the split cycle concept. The Scuderi engine works on the split cycle and gives higher efficiency than the previous split cycle engines resulting overall high perform ance. It also eliminates the problems faced by previous engines based on the spl it cycle in terms of breathing (volumetric efficien cy) and thermal efficiency. This paper throws light on the greater volumetric,thermal and overall efficiency key points related t o the Scuderi Engines.

STUDY OF SOLAR THERMAL CAVITY RECEIVER FOR PARABOLIC CONCENTRATING COLLECTOR ijiert bestjournal
Energy is one of the building blocks of the country . The growth of the country has been fueled by chea p,abundant energy resources. Solar energy is a form of renewable ener gy which is available abundantly and collected unre servedly. The parabolic concentrator reflects the direct incident solar rad iation onto a receiver mounted above the dish at it s focal point. The conversion of concentrated solar radiation to heat takes place in receiver. The heat transfer characteristics of the receiver changes during the rotation of the receiver which affects thermal performance. The working temperature may also influence the ther mal performance and overall efficiency of the system. Thermal as well as optica l losses affect the performance of a solar paraboli c dish-cavity receiver system. The thermal losses of a solar cavity receiver include c onvective and radiative losses to the air in the ca vity and conductive heat loss through the insulation used behind the helical tube surface. Convective and radiative heat losses form the major constituents of the thermal losses. The convection heat loss from cavit y receiver in parabolic dish solar thermal power sy stem can significantly reduce the efficiency and consequently the cost effectiveness of the system. It is important to assess this heat loss and subsequently improve the thermal performance of the receiver.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

ABSTRACT
The automobile engine connecting rod is a high volume production, critical component. It connects reciprocating piston to
rotating crankshaft, transmitting the thrust of the piston to the crankshaft. Every vehicle that uses an internal combustion engine
requires at least one connecting rod depending upon the number of cylinders in the engine. As the purpose of the connecting rod is
to transfer the reciprocating motion of the piston into rotary motion of the crankshaft. Connecting rods for automotive applications
are typically manufactured by forging from either wrought steel or powdered metal. the material used for this process is Mg-Alloy
and also finite element analysis of connecting rod
INTRODUCTION
Connecting rods for automotive applications are typically manufactured by forging from either wrought steel or powdered
metal. They could also be cast. However, castin gs could have blow-holes which are detrimental from durability and fatigue points
of view. The fact that forgings produce blow-hole-free and better rods gives them an advantage over cast rods. Between the
forging processes, powder forged or drop forged, each process has its own pros and cons. Powder metal manufactured blanks have
the advantage of being near net shape, reducing material waste. However, the cost of the blank is high due to the high material
cost and sophisticated manufacturing techniques. With steel forging, the material is inexpensive and the rough part manufacturing
process is cost effective. Bringing the part to final dimensions under tight tolerance results in high expenditure for machining, as
the blank usually contains more excess material. The main objective of this study was to explore weight and cost reduction
opportunities for a production forged steel connecting rod. This has entailed performing a detailed load analysis. Therefore, this
study has dealt with two subjects, first, dynamic load and quasi-dynamic stress analysis of the connecting rod. The loads acting on
the connecting rod as a function of time were obtained. The relations for obtaining the loads and accelerations for the connecting
rod at a given constant speedof the crankshaft were also determined. Quasidynamic finite element analysis was performed at
several crank angles. The stress-time history for a few locations was obtained. The difference between the static FEA,
quasidynamic FEA was studied.
Based on the observations of the quasi-dynamic FEA, static FEA and the load analysis results, the load for the optimization study
was selected. The results were also used to determine the variation of R-ratio, degree of stress multiaxiality, and the fatigue model
to be used for analyzing the fatigue strength. The component was optimized for weight and cost subject to fatigue life and space
constraints and manufacturability. It is the conclusion of this study that the connecting
rod can be designed and optimized under a load range comprising tensile load corresponding to 360° crank angle at the maximum
engine speed as one extreme load, and compressive load corresponding to the peak gas pressure as the other extreme load.
Furthermore, the existing connecting rod can be replaced with a new connecting rod made of C-70 steel that is 10% lighter and
25% less expensive due to the steel’s fracture crack ability. The fracture crack ability feature facilitates separation of cap from rod
without additional machining of the mating surfaces. Yet, the same performance can be expected in terms of component
durability.
