Fatigue or Durability Analysis of Steering Knuckleijsrd.com
the purpose of the study of this thesis is to discuss analysis the acting force upon the steering knuckle while in track or random load for a vehicle. Steering knuckle is main important part in the vehicle because that requires lots of attention in selection because once it is damaged then it have to replace with the new one. Structural Components such as a steering knuckle might be strong enough to withstand a single applied load. But what happens when the part operates over and over, day after today? To predict component failure in such cases requires what's called fatigue or durability analysis. For our purposes, a constant or static load does not cause failure. What counts is the impact of working or fluctuating loads. Failures, or fractures, take place when cracks get so large that remaining material can no longer endure stresses and strains. In classic structural analyses, failure predictions are based solely on material strength or yield strength. Durability analysis goes beyond this, evaluating failure based on repeated simple or complex loading.

An excavator is a typical hydraulic heavy-duty human-operated machine used in general versatile construction operations,
such as digging, ground leveling, carrying loads, dumping loads and straight traction. Normally backhoe excavators
are working under worst working conditions. Due to severe working conditions, excavator parts are subjected to
high loads and must work reliably under unpredictable working conditions. Thus, it is necessary for the designers to
provide not only an equipment of maximum reliability but also of minimum weight and cost, keeping design safe under
all loading conditions.

These days we have an increased number of heart diseases including increased risk of heart attacks. Our proposed system users sensors that allow to detect heart rate of a person using heartbeat sensing even if the person is at home. The sensor is then interfaced to a microcontroller that allows checking heart rate readings and transmitting them over internet. The user may set the high as well as low levels of heart beat limit. After setting these limits, the system starts monitoring and as soon as patient heart beat goes above a certain limit, the system sends an alert to the controller which then transmits this over the internet and alerts the doctors as well as concerned users. Also the system alerts for lower heartbeats. Whenever the user logs on for monitoring, the system also displays the live heart rate of the patient. Thus concerned ones may monitor heart rate as well get an alert of heart attack to the patient immediately from anywhere and the person can be saved on time.This value will continue to grow if no proper solution is found. Internet of Things (IoT) technology developments allows humans to control a variety of high-tech equipment in our daily lives. One of these is the ease of checking health using gadgets, either a phone, tablet or laptop. we mainly focused on the safety measures for both driver and vehicle by using three types of sensors: Heartbeat sensor, Traffic light sensor and Level sensor. Heartbeat sensor is used to monitor heartbeat rate of the driver constantly and prevents from the accidents by controlling through IOT.
ABSTRACT The success of the cloud computing paradigm is due to its on-demand, self-service, and pay-by-use nature. Public key encryption with keyword search applies only to the certain circumstances that keyword cipher text can only be retrieved by a specific user and only supports single-keyword matching. In the existing searchable encryption schemes, either the communication mode is one-to-one, or only single-keyword search is supported. This paper proposes a searchable encryption that is based on attributes and supports multi-keyword search. Searchable encryption is a primitive, which not only protects data privacy of data owners but also enables data users to search over the encrypted data. Most existing searchable encryption schemes are in the single-user setting. There are only few schemes in the multiple data users setting, i.e., encrypted data sharing. Among these schemes, most of the early techniques depend on a trusted third party with interactive search protocols or need cumbersome key management. To remedy the defects, the most recent approaches borrow ideas from attribute-based encryption to enable attribute-based keyword search (ABKS
Cloud computing is the one of the emerging techniques to process the big data. Large collection of set or large
volume of data is known as big data. Processing of big data (MRI images and DICOM images) normally takes
more time compare with other data. The main tasks such as handling big data can be solved by using the concepts
of hadoop. Enhancing the hadoop concept it will help the user to process the large set of images or data. The
Advanced Hadoop Distributed File System (AHDF) and MapReduce are the two default main functions which
are used to enhance hadoop. HDF method is a hadoop file storing system, which is used for storing and retrieving
the data. MapReduce is the combinations of two functions namely maps and reduce. Map is the process of
splitting the inputs and reduce is the process of integrating the output of map’s input. Recently, in medical fields
the experienced problems like machine failure and fault tolerance while processing the result for the scanned
data. A unique optimized time scheduling algorithm, called Advanced Dynamic Handover Reduce Function
(ADHRF) algorithm is introduced in the reduce function. Enhancement of hadoop and cloud introduction of
ADHRF helps to overcome the processing risks, to get optimized result with less waiting time and reduction in
error percentage of the output image
Text mining has turned out to be one of the in vogue handle that has been joined in a few research
fields, for example, computational etymology, Information Retrieval (IR) and data mining. Natural
Language Processing (NLP) methods were utilized to extricate learning from the textual text that is
composed by people. Text mining peruses an unstructured form of data to give important
information designs in a most brief day and age. Long range interpersonal communication locales
are an awesome wellspring of correspondence as the vast majority of the general population in this
day and age utilize these destinations in their everyday lives to keep associated with each other. It
turns into a typical practice to not compose a sentence with remedy punctuation and spelling. This
training may prompt various types of ambiguities like lexical, syntactic, and semantic and because of
this kind of indistinct data; it is elusive out the genuine data arrange. As needs be, we are directing
an examination with the point of searching for various text mining techniques to get different
textual requests via web-based networking media sites. This review expects to depict how
contemplates in online networking have utilized text investigation and text mining methods to
identify the key topics in the data. This study concentrated on examining the text mining
contemplates identified with Facebook and Twitter; the two prevailing web-based social networking
on the planet. Aftereffects of this overview can fill in as the baselines for future text mining research.
Colorectal cancer (CRC) has potential to spread within the peritoneal cavity, and this transcoelomic
dissemination is termed “peritoneal metastases” (PM).The aim of this article was to summarise the current
evidence regarding CRC patients at high risk of PM. Colorectal cancer is the second most common cause of cancer
death in the UK. Prompt investigation of suspicious symptoms is important, but there is increasing evidence that
screening for the disease can produce significant reductions in mortality.High quality surgery is of paramount
importance in achieving good outcomes, particularly in rectal cancer, but adjuvant radiotherapy and chemotherapy
have important parts to play. The treatment of advanced disease is still essentially palliative, although surgery for
limited hepatic metastases may be curative in a small proportion of patients.
Heat transfer in pipes is a distinctive kind of procedure employed in heat exchanger which transfers great
deal of heat because of the impact of capillary action and phase change heat transfer principle. Late improvement
in the heat pipe incorporates high thermal conductivity liquids like Nano liquids, fixed inside to extricate the most
extreme heat. This paper audits, impact of different factors, for example, thermal pipe tilt edge, charged measure
of working liquid, nano particles sort, size, and mass/volume part and its impact on the change of thermal
proficiency, thermal exchange limit and decrease in thermal protection. The Nano liquid arrangement and the
examination of its thermal attributes likewise have been investigated. The retained sun oriented vitality is
exchanged to the working liquid streaming in the pipe. The execution of the framework is affected by thermal
exchange from tube to working liquid, with least convective misfortunes, which must be considered as one of the
essential plan factor. In tube and channel streams, to improve the rate of heat exchange to the working liquid,
detached enlargement methods, for example, contorted tapes and swirl generators are employed from the fluid
flow path. The variation of heat transfer coefficient and pressure drop in the pipe flow for water and water based
Al2O3 Nano fluids at different volume concentrations and twisted tapes are studied.

I.INTRODUCTION:
The enhancing of engine bracket system
has been the subject of interest for many years for
the researchers. The main function of an engine
mounting bracket is to properly balance the power
pack on the vehicle chassis for good motion control
as well as good isolation[1-2].In an automotive
vehicle such as bus, the engine rests on brackets
which are connected to the main-frame or the
skeleton of the Vehicle. Hence, during its function
the undesired vibrations produced by the engine
and roughness of the road will be transferred to the
frame of the vehicle through the brackets [3] and
which may leads to the discomfort to the
commuter(s) or even generate the cracks in the
chassis. It is necessary to design proper engine
bracket for a bus. As such, engine bracket has been
designed as a framework to support engine.
Vibrations and fatigue of engine bracket leads to
structural failure if the resulting vibrations and
stresses are severe and excessive. Prolonged
exposure to whole-body vibration in the working
environment may lead to fatigue and in some cases
it damages the vehicle.
Generally, the most important vibration
relevant excitations in an engine can be identified
as follows:- combustion force; main bearing
reaction forces including mass forces damper
function and flywheel whirling, modified by the
front-end damper; piston side forces including
secondary motion; camshaft bearing reaction forces
including mass forces, opening and closing impacts
and bearing impacts; valve opening and closing
impacts; valve train forces caused by chain/belt
movement or gear drive; gear train forces inside the
transmission; drive train reaction forces and
moments[4-8]. There are two major problems that
engineers must deal with when it comes to
vibration isolation. The first problem is force
isolation, which is frequently encountered in
rotating or reciprocating machinery with
unbalanced masses. The main objective in this
problem is to minimize the force transmitted from
the machine to the supporting foundation [9].
The second problem is motion isolation.
This is broadly achieved by mounting equipment
on a resilient support or an isolator such that the
natural frequency of the equipment-support system
is lower than the frequency of the incoming
vibrations to be isolated. The natural frequency of
the mounting system should be lower than the
engine disturbance frequency to avoid the
excitation of the mounting system resonance. This
will ensure a low transmissibility. In diesel engines
the engine mounting is one of the major problems.
Due to the Un-throttled condition, and higher
compression ratio of the diesel engine, the speed
irregularities particularly at low Speed and Low
load conditions and are significantly higher than
gasoline engines. By optimizing the thickness and
shape of major mounting points made it possible to
design a vehicle with optimized weight and
RESEARCH ARTICLE OPEN ACCESS
Abstract:
Engine is one of the most significant component of road vehicles. High performance vehicles have their
engine supported by bracket. The engine mounting plays an important role in reducing the noise and vibrations, improving the
comfort and work environment of a vehicle. The present work deals with design modification of engine mounting bracket.
Modelling work has been carried out with commercial desktop CAD software and analyzed the modal performance with
Analysis software. Ribs has been adopted to the existing mounting bracket for its better performance structural, thermal and
modal analysis has been carried out with analysis software. Aluminium alloy, aluminium silicon carbide and magnesium alloy
are considered as the different materials of mounting bracket. Based on the analysis it is found that the aluminium silicon
carbide is superior suited for the modified V6 engine mounting bracket.

performance at initial designing stages [10].
Studies shows that the brackets saved 38% mass
(0.86 kg the expected and resultant benefit is
different for each application. Range of savings are
20% to 38% in the authors’ experience to 0.53kg)
[11]. Engine induced vibrations may be divided
into two main categories: (a) low-frequency
vibrations, in which the rigid body motion modes
are engaged, and (b)high-frequency vibrations, in
which structure-borne noises may alter the
passenger’s comfort. Almost all research performed
so far in the field of optimal isolation of the engine-
induced vibration has been restricted to the first
category [12-15].
II.MATERIAL SELECTION:
Generally the engine mounting bracket is
made up of Steel, Aluminium Alloy, Cast Iron and
Rubber Elastomers. It is also observed that the
usage of Grey Cast Iron is very recommendable to
the present day requirements and also the usage of
the steel although give the greater stability to the
Product but gives a very heavy weight to the
product. It is also made to know that the usage of
the Aluminium Silicon Carbide (AlSiC) materials
give the greater stability to the component. This
paper gives the detailed analysis about the
applicability of AlSiC Composite Material in
comparison with that of the Aluminium Alloy and
Magnesium alloy. The materials properties of these
alternatives are shown in table1.
Table 1: MATERIAL PROPERTIES
III.PROPOSED METHODOLOGY:
The purpose of engine mounting bracket is
to support the engine and sustain the vibrations
caused by engine as well as bumps from tires due
to uneven road surfaces. The key areas for
modification are identified such as ribs in the
mounting bracket. The 3-Dimensional model of
engine mounting bracket is prepared. The existing
model of engine mounting bracket compare to the
modified model is done and analysis is carried out
using Analysis software.
IV.OBJECTIVE:
To carry out the structural, thermal and
modal analysis for finding the stresses,
deformation, heat flux& mode shapes and
Frequency response analysis to analyze the
response of the structure in terms of displacements
and stresses for different models.
V.MODELLING OF ENGINE MOUNTING
BRACKET:
Computer Aided Design (CAD) has
become more popular, reverse engineering has
become a viable method to create a 3D virtual
model of an existing physical part for use in 3D
CAD, CAM, CAE or other software. The reverse
engineering process involves measuring an object
and then reconstructing it as a 3D model. The
physical object can be measured by using 3D
scanning and manual measuring.CATIA (Computer
Aided Three dimensional Interactive Application)
is a one of the world's leading high end software
package. CATIA is a multi-platform commercial
software suite developed by Dassault Systems and
marketed world-wide by IBM.CATIA is written in
the C++ programming language. By using the
CATIA V5 Software modelling work of engine
mount bracket is done.

VI.ANALYSIS OF ENGINE MOUNTING
BRACKET:
Finite element analysis (FEA) is one of the
most popular engineering analysis methods for
Non-linear problems.FEA requires a finite element
mesh as a geometric input. This mesh can be
generated directly from a solid model for the
detailed part model designed in a three-
(3D) CAD system. The importance of the mesh
in the whole process of analysis is very important
from the point of result implementation. By size
and shape of the meshing accurate results can carry
out. By using selected material properties to
analyze the original and modified Engine Mounting
Bracket as follows.
6.1. STRUCTURAL ANALYSIS:
Structural analysis is probably the most
common application of the finite element method
as it implies bridges and buildings, naval,
aeronautical, and mechanical structures such as
ship hulls, aircraft bodies, and machine housings,
as well as mechanical components such as pistons,
machine parts, and tools. The structural analysis
done at different Models using different materials
Aluminum Alloy, Magnesium Alloy, Aluminum
Silicon Carbide respectively.

VII.REGRESSION ANALYSIS:
Regression analysis is used when two or
more variables are thought to be systematically
connected by a linear relationship. Regression
analysis is applied to the mounting bracket analysis
results. Based on the regression analysis the
following value has been obtained.
Multiple R = 0.99
R Square = 0.98
F = 213.93
t = 14.62
Where, R Square = Squared Multiple correlation
co- efficient.
F = Fitted regression
t = Test statistics.
In the above, Multiple R and R square
values are having the confidence level is above the
95% for deformation .It found to be, the regression
analysis values for deformation is significant.
VIII. CONCLUSION:
Analysis of engine mounting bracket with
and without rib is carried out. By observing the
structural analysis the stress values are less for
aluminium silicon carbide among other materials.
By observing the thermal analysis adding ribs on
the engine mounting bracket, the heat flux values

are increasing, so heat transfer rate increases. By
comparing for materials, the heat values are more
for aluminium silicon carbide among other
materials. By observing the modal analysis adding
ribs on the engine mounting bracket, the
deformation and frequency values are increasing.
By comparing for materials, the deformation and
frequency values are less when aluminium silicon
carbide among other materials.
So, it can be concluded that by adding
ribs, the stress values are decreasing and heat
transfer rate values increasing. So modifying the
design is found to be good as per structural and
thermal analysis but as per modal analysis the
values are good for existing model. The input and
output parameters are tested by Regression analysis
and it is found to be significant.
IX.FUTURE SCOPE:
Further, the work can be extended to other
strength-weight alloys; design optimization can
also be done on V6 engine mounting bracket which
focuses on the reduction of cost.
X.FUTURE SCOPE:
I wish to thank all faculty members of
Mechanical Engineering Department AITS
Rajampet, for their valuable support to complete
my work.
