Finite Element Analysis of Fire Truck Chassis for Steel and Carbon Fiber Mate...IJERA Editor
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.

A review on stress analysis and weight reduction of automobile chassiseSAT Journals
Abstract
Chassis is the term used to define the basic structure of the vehicle. It is also referred to as carrying unit as all the units including
body are mounted on it. There are various loads acting on the chassis like inertia loads, static loads, over loads, etc. also it has to
withstand the forces induced due to sudden braking and acceleration. In this paper a review has been made on the stress analysis
of chassis by finite element analysis software packages like ANSYS, HyperWorks, etc. Weight reduction is gaining importance as
the designers are trying to reduce the excess weight form the existing vehicle design. A review of the various techniques for weight
reduction for the chassis is presented.

Design and fabrication of variable steering ratio mechanism for light Motor v...sushil Choudhary
To facilitate easy and proper steering of the vehicle while negotiating a turn, as per the requirements of driver in
different situations like hair pin bends in hilly regions, sudden turns in highways and city streets or in sports car
during race events an improved steering system is needed to address these problems. The steering arrangement
used in a normal automobile was investigated and to solve the above problems a variable steering ratio
mechanism was designed and fabricated, with the aim to determine if incorporation of variable steering ratio
mechanism will make an improvement in the steady and transient state handling of the automobile. The size of
the pinion gear and the number of teeth on the gear determine the rack-and-pinion steering ratio. The steering
wheel must be turned one revolution to turn the front wheels one sixteenth of a turn, the steering ratio is 1 to
1/16. Reversing the numbers gives a ratio of 16 to 1, or 16:1. This steering ratio is always fixed. A variable
steering ratio mechanism was fabricated by using constant mesh type gears from Bajaj-Super and steering
mechanism from Tata-Nano. Gear housing using wood is created and gear shifting arrangement incorporated. It
was observed that on engaging the 1st gear steering ratio is increased to 9.92:1. On engaging the 2nd gear
steering ratio is increased to 7.20:1, On engaging the 3rd gear steering ratio is increased to 4.96:1 On engaging
the 4th gear steering ratio is increased to 3.52:1. The effort required for steering is increased due to these ratios
as energy is lost due to friction. This mechanism can only be practical if used in conjugation with power assist.

Failure investigation of axle box spring of railway 16 t coacheseSAT Journals
Abstract Spring is an elastic member whose main function is to deflect or distort under load and to recover its original shape when lo ad is removed. The springs used in the bogie suspension of Railway coaches are helical compression springs. Visual examination shows that failure is common between first to third coils. The exact time of failure cannot be determined as the coaches come for POH after 18 months. Some cracks also negotiate during load testing. Pattern of cracks showing it may subject to transverse forces. The cracks are detected in Magnaflux testing. The present works attempt to analyze design of primary suspension springs used in Railway coaches under transverse loading while negotiating curved path by using ANSYS 14.5 software. Stresses induced are compared with allowable stresses. Typical 16T coaches have been considered for the failure analysis. Keywords: Helical compression springs, load & stress calculation, POH, ANSYS 14.5, Modeling, Primary Suspension system, axle box spring, Bolster spring, Creo 2.0.
SIZE OPTIMIZATION DESIGN OF THREEWHEELED MOTORCYCLE FRAME WITH CARGO BOXIAEME Publication
A size optimization design method for the frame of a three-wheeled motorcycle
with a cargo box is proposed considering high load and motion conditions that may
occur under straight-driving and curve-driving conditions. The existing frame of a
three-wheeled motorcycle with a cargo box was compared with the frame under high
load through finite-element analysis by applying longitudinal bending and torsion,
and the thicknesses of the members that exceeded allowable stress were optimized
using the design of experiments. The comparison and analysis of both the existing
model and the optimally designed model confirmed that the frame strength was
improved compared with the existing frame.

Structural Analysis of Ladder Chassis Frame for Jeep Using Ansys IJMER
Automotive chassis frame is an important part of an automobile. The automotive chassis
frame is the structural backbone of any vehicle. The main function of chassis frame is to support the
body, different parts of an automobile and topayload placed upon it.The chassis frame has to withstand
the stresses developed as well as deformation occurs in it and to withstand the shock, twist vibration
and other stresses. Its principle function is to carry the maximum load for all designed operating
condition safelythat should be within a limit. On chassis, frame maximum shear stress and deflection
under maximum load are important criteria for design andanalysis. In these projects, we
havecalculated the von mises stress and shear stress for the chassis frame and the finite element
analysis has been donefor the validation on the chassis frame model of jeep. We have taken certain
material as Mild sheet steel, aluminium alloy and titanium alloy for the rectangular hollow box type to
design chassis frame of jeep.

Stress Analysis of Automotive Chassis with Various ThicknessesIOSR Journals
Abstract : This paper presents, stress analysis of a ladder type low loader truck chassis structure consisting of
C-beams design for application of 7.5 tonne was performed by using FEM. The commercial finite element
package CATIA version 5 was used for the solution of the problem. To reduce the expenses of the chassis of the
trucks, the chassis structure design should be changed or the thickness should be decreased. Also determination
of the stresses of a truck chassis before manufacturing is important due to the design improvement. In order to
achieve a reduction in the magnitude of stress at critical point of the chassis frame, side member thickness,
cross member thickness and position of cross member from rear end were varied. Numerical results showed that
if the thickness change is not possible, changing the position of cross member may be a good alternative.
Computed results are then compared to analytical calculation, where it is found that the maximum deflection
agrees well with theoretical approximation but varies on the magnitude aspect.
Keywords - Stress analysis, fatigue life prediction and finite element method etc.

We have focused on every point of roll cage to improve the performance of vehicle without failure of roll cage. We began the task of designing by conducting extensive research of ATV roll cage through finite element analysis. A roll cage is a skeleton of an ATV. The roll cage not only forms the structural base but also a 3-D shell surrounding the occupant which protects the occupant in case of impact and roll over incidents. The roll cage also adds to the aesthetics of a vehicle. The design and development comprises of material selection, chassis and frame design, cross section determination, determining strength requirements of roll cage, stress analysis and simulations to test the ATV against failure.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Structural Analysis of Truck Chassis Frame
and Design Optimization for Weight Reduction
Hirak Patel, Khushbu C. Panchal, Chetan S. Jadav
Abstract- Automotive chassis is an important part of an
automobile. The chassis serves as a frame work for supporting the
body and different parts of the automobile. Also, it should be rigid
enough to withstand the shock, twist, vibration and other stresses.
Along with strength, an important consideration in chassis design is
to have adequate bending stiffness for better handling
characteristics. So, maximum stress, maximum equilateral stress
and deflection are important criteria for the design of the chassis.
This report is the work performed towards the optimization of the
automotive chassis with constraints of maximum shear stress,
equivalent stress and deflection of chassis. Structural systems like
the chassis can be easily analyzed using the finite element
techniques. A sensitivity analysis is carried out for weight
reduction. So a proper finite element model of the chassis is to be
developed. The chassis is modeled in PRO-E. FEA is done on the
modeled chassis using the ANSYS Workbench.
Index Terms—optimization, sensitivity, deformation, stress
I. INTRODUCTION
The major challenge in today’s ground vehicle industry is to
overcome the increasing demands for higher performance,
lower weight, and longer life of components, all this at a
reasonable cost and in a short period of time. The chassis of
trucks is the backbone of vehicles and integrates the main
truck component systems such as the axles, suspension, power
train, cab and trailer. Since the truck chassis is a major
component in the vehicle system, it is often identified for
refinement. There are many industrial sectors using this truck
for their transportations such as the logistics, agricultures,
factories and other industries.

III. OPTIMIZATION OF CHASSIS FRAME
Optimization is define as a maximization of wanted properties
and minimization of unwanted properties.
In case of structural optimization the chassis:
Desired Properties are:
Strength
Stiffness
Deflection etc…
Undesired Properties:
Material
Cost
Weight etc…
In the case of chassis we can reduce the weight of chassis
frame by reducing its thickness, but it will increase the
deflection as well as the shear stress. To omit this problem the
sensitivity analysis will be helpful to reduce thickness of cross
section of chassis frame.
Sensitivity analysis
To analyze the sensitivity of frame web height to the change in
thickness and viceversa. For the approximately same section
modulus and flange width.
