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.

Material Optimization and Weight Reduction of Drive Shaft Using Composite Mat...IOSR Journals
The objective of the drive shaft is to connect with the transmission shaft with the help of universal joint whose axis intersects and the rotation of one shaft about its own axis results in rotation of other shaft about its axis. Shafts must be exceptionally tough and light to improve the overall performance of the vehicle. Automobile industries are exploring composite materials in order to obtain reduction of weight without significant decrease in vehicle quality and reliability. This is due to the fact that the reduction of weight of a vehicle directly impacts its fuel consumption. Particularly in city driving, the reduction of weight is almost directly proportional to fuel consumption of the vehicle. Also at the start of vehicle the most of the power get consumed in driving transmission system, if we able to reduce the weight of the propeller shaft that surplus available power can be used to propel the vehicle. Thus, in this paper, the aim is to replace a two-piece metallic drive shaft by a composite drive shaft. The following materials can be chosen Steel, Boron/Epoxy Composite, Kevlar/Epoxy Composite, Aluminum – Glass/Epoxy Hybrid, Carbon – Glass/Epoxy Hybrid. The analysis was carried out for three different ply orientations of the composites in order to suggest the most suitable ply orientation of the material that would give the maximum weight reduction while conforming to the stringent design parameters of passenger cars and light commercial vehicle.

Design analysis of the roll cage for all terrain vehicleeSAT Journals
Abstract We have tried to design an all terrain vehicle that meets international standards and is also cost effective at the same time. 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. Keywords: Roll cage, material, finite element analysis, strength
Parametric Optimization of Eicher 11.10 Chassis Frame for Weight Reduction Us...IOSR Journals
Abstract: The chassis serves as a backbone for supporting the body and different parts of the automobile. 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. The main objective of the
research is to obtain the minimum weight of Eicher 11.10 chassis frame. The chassis frame is made of two side
members joined with a series of cross members. The number of cross members, their locations, cross-section
and the sizes of the side and the cross members becomes the design variables. The chassis frame model is to be
developed in Solid works and analyzed using Ansys. Since the no. of parameters and levels are more, the
probable models are too many. So, to select optimum parameters among them large no of modeling and analysis
work is involved which consumes more time. To overcome this problem TAGUCHI method along with FEA is
use. The weight reduction of the side bar is achieved by changing the Parameters using orthogonal array. Then
FEA is performed on those models to get the best solution. This method can save material used, production cost
and time.

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.
Keywords - Big End fillet section ,Connecting Rod, Compressive Stresses , Failure of Connecting Rod, FEA,

NONLINEAR FINITE ELEMENT ANALYSIS FOR REINFORCED CONCRETE SLABS UNDER PUNCHIN...IAEME Publication
This paper presents an implementation of a three-dimensional nonlinear finite element model for evaluating the behavior of reinforced concrete slabs under centric load. The concrete was idealized by using eight-nodded solid elements. While flexural reinforcement and the shear were modeled as line elements, a perfected bond between solid elements and line elements was assumed. The nonlinear behavior of concrete in compression is simulated by an elasto-plastic work-hardening model, and in tension a suitable post-cracking model based on tension stiffening and shear retention models are employed. The steel was simulated using an elastic-full plastic model. The validity of the theoretical formulations and the program used was verified through comparison with available experimental data, and the agreement has proven to be good. A parametric study has been also carried out to investigate the influence of the slab thickness on column-slab connection response
Design and Optimisation of Sae Mini Baja ChassisIJERA Editor
The objective is to design and develop the roll cage for All - Terrain Vehicle accordance with the rulebook of BAJA 2014 given by SAE. The frame of the SAE Baja vehicle needs to be lightweight and structurally sound to be competitive but still protect the driver. The vehicle needs to traverse all types of off-road conditions including large rocks, downed logs, mud holes, steep inclines, jumps and off camber turns. During the competition events there is significant risk of rollovers, falling from steep ledges, collisions with stationary objects, or impacts from other vehicles. Material for the roll cage is selected based on strength and availability. A software model is prepared in Pro-engineer. Later the design is tested against all modes of failure by conducting various simulations and stress analysis with the aid of ANSYS 13. Based on the result obtained from these tests the design is modified accordingly. A target of 2 is set for Yield Factor of Safety.
FEA Based Validation of Weld Joint Used In Chassis of Light Commercial Vehicl...ijiert bestjournal
Generally automotive systems are subjected to dynam ic and static loads,due to hives driving and adverse conditions of the road surface,thus it causes cracks,noise,vibration and failure in an automobile,since in general the total effect of work for automobile system is lowered. Such effect is arising due to behaviour in types of loading,construction and condition of the work where the automobile system is and reducing it s strength. Therefore however most of the Light Commercial Vehicles (LCV) chassis are man ufactured by welding to reduce the weight of the chassis. Hence there is a more stress concentration occurs at a welded joint region. The fundamental task is to develop a model of welded joint to sustain various loads of LCV chassis. Effect of different design parameters,properties of material are observed with respect to the strength of the weld and location of stress concentrations are identified. During the design process model parameters are often alter ed to evaluate alternative welding joining choices,to reduce weight of the system to sustain varying loading conditions without failure.

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.
I. INTRODUCTION
The chassis of trucks is the backbone of vehicles and integrates the main component systems such as
the axles, suspension, power train, cab and trailer, and is usually subjected to the weight of cabin, its content,
and inertia forces arising due to roughness of road surfaces etc. (i.e. static, dynamic and cyclic loading). The
stress analysis is important in fatigue study and life prediction of components to determine the highest stress
point commonly known as critical point which initiates to probable failure, this critical point is one of the factors
that may cause the fatigue failure. The magnitude of the stress can be used to predict the life span of the chassis.
The location of critical stress point is thus important so that the mounting of the components like engine,
suspension, transmission and more can be determined and optimized, Finite Element Method (FEM) is one of
the method to locate the critical point [1,2]. Safety factor is used to provide a design margin over the theoretical
design capacity. This allows consolidation of uncertainties in the design process [3].Jadav Chetan S. et al
reviews various factors affecting the fatigue life of an structure like cyclic stress state, geometry, surface quality,
material type, residual stresses, size and distribution of internal defects, direction of loading & grain size [4].
In this study, chassis structures are comparing by the thicknesses of the profiles. For determining the
strength of the frame, structural analyses were performed for these frames of thicknesses of 4, 5, 6 mm and also
changing the position of cross member and change the thickness of cross member near high stress zone. The
truck chassis was modeled and the finite element analyses were solved in CATIA V5R10.
During this five different cases consider to study the effect of thickness on chassis stresses
Case 1 Thickness of Side member is 4 mm.
Case 2 Thickness of Side member is 5 mm.
Case 3 Thickness of Side member is 6 mm.
Case 4 Change position of 4th
Cross member at 2520 from rear end.
Case 5 Thickness of 5th
Cross member is 5 mm.
II. LITERATURE REVIEW
Roslan Abd Rahman et al [1] does stress analysis of heavy duty truck chassis by utilizing a commercial
finite element package ABAQUS. To determine critical point so that by design modifications the stresses can be
reduces to improve the fatigue life of components. During this he uses ASTM low alloy steel a 710 C (Class 3)
with 552 MPa of yield strength and 620 MPa of tensile strength for chassis founds the maximum stress 386.9
MPa at critical point occurred at opening of chassis This critical point is located at element 86104 and node
16045, which is in contacted with the bolt from this he concludes that this critical point is an initial to probable
failure.
Cicek Karaoglu et al [2] does stress analysis of heavy duty truck chassis with riveted joints by utilizing
a commercial finite element package ANSYS version 5.3.during this study, he examine the effect of the side
member thickness and connection plate thickness with length change, the side member thickness is varied from
8 to 12 mm, and the thickness of the connection plate is also varied from 8 to 12 mm by local plate, the

connection plate thickness is varied from 7 to 10 mm, and the length of the connection plate (L) is varied from
390 to 430 mm. from this he concluded that if the change of the side member thickness using local plates is not
possible, due to increase weight of chassis then choosing an optimum connection plate length (L) seems to be
best practical solutions for decreasing the stress values.
Mohd Azizi Muhammad Nor et al [3] performs the stress analysis of an actual low loader structure
consisting of I-beams design application of 35 tonne trailer. He uses modeling software CATIA V5R18. The
results of analysis revealed that the location maximum deflection and maximum stress agrees well with
theoretical maximum location of simple beam under uniform loading distribution. This study found out that
there is discrepancy between the theoretical (2-D) and numerical (3-D FEA) results. It is observed that the
maximum deflection is pointed in situated in between BC1 and BC2 with magnitude of 7.79mm. The results of
the numerical analysis revealed that the location maximum deflection and maximum stress agrees well with
theoretical maximum location of simple beam loaded by uniform force.
Jadav Chetan S et al [4] review the investigations that have been made on the different fatigue analysis
techniques of automobile frames.
N.K.Ingole et al [5] does the modifications in existing model of tractor trailer chassis by 1) Variation in
Cross sectional areas of cross members, 2) Variation in cross sectional areas of cross and longitudinal members,
3) Variation in cross sectional areas of cross and longitudinal members and 4) Changing the position of cross
members of main frames of chassis, Considering variable cross sectional areas of cross and longitudinal
members. It has been found that, maximum stress present in existing chassis is 75 MPa and weight of chassis is
751.82 kg. Case 4 leads to maximum weight reduction of approx 112 kg as compared to case 1, 2 and 3. So
modifications as per case 4 are also recommended, case 3 the weight reduction is 88 kg with maximum stress
level in range of 25MPa to 66 MPa.
III. BASIC CALCULATION FOR CHASSIS FRAME
For Case 1
Model No. = 10.75 (Eicher)
Side bar of the chassis are made from “C” Channels with 200mm x 55 mm x 5 mm
Front Overhang (a) = 1005 mm.
Rear Overhang (c) = 1305 mm.
Wheel Base (b) = 3515 mm. Material of the chassis is Steel
Table 1Material properties of the Truck Chassis Steel
Young’s Modulus 200 GPa.
Poisson’s Ratio 0.266.
Density 7860 Kg/m3
.
Yield Strength 250 MPa.
Symmetry Linear Isotropic.
Capacity of Truck = 7.5 ton = 7500 kg = 73575 N.
Capacity of Truck with 1.25% = 9375 N = 91968.75 N.
Weight of the body and engine = 2 ton = 2000 kg = 19620 N
Total load acting on chassis = Capacity of the Chassis + Weight of body and engine
= 91968.75 + 19620
= 111588.75 N
Chassis has two beams. So load acting on each beam is half of the Total load acting on the chassis. Load acting
on the single frame =111588.75/2 = 55794.375 N / Beam.
Uniformly Distributed Load is 55794.375 / 5825 =9.578 N/mm.

VI. Conclusion
The analyses are processed in the static and structural conditions. From comparison for 4mm thickness the
highest stress occurred is 123.83 MPa by FE analysis and the calculated maximum shear stress is 123.83
Mpa. The maximum displacement of numerical simulation result is 0.288 mm. The difference is caused by
simplification of model and uncertainties of numerical calculation and improper meshing.

Comparing case 5 with case 2 only by increasing thickness of cross member weight is increases by 2.92 Kg
stresses are decreased by 43.8 N/mm2
, and displacement is increased by 0.022mm.
Comparing case 4 with case 2 only by changing the position of cross member weight is not affecting
stresses are deceases by 06.7 N/mm2
, and displacement is increased by 0.026 mm.
Comparing case 3 with case 2 only by increasing 23.58 Kg stresses are increased by 06.5 N/mm2
, and
displacement is increased by 0.024mm.
Hence it is better to change the thickness of cross member at critical stress point than changing the thickness of
side member and position of chassis for reduction in stress values and deflection of chassis.
