Vibration measurement and spectral analysis of chassis frame mounted structur...Dr.Vikas Deulgaonkar
Chassis mounted structure is a base component for shelters or containers mounted on heavy transport vehicles. When the vehicle is driven in rough terrains or during off-road transportation this structure has a significant role in protecting the sophisticated cargo and intelligent tracking systems placed inside the shelters. During off-road transportation or warhead conditions the vehicle is subjected to large unevenness in load due to road or soil irregularities in rough terrains, which causes vibrations to be induced in the vehicle. As the nature of vibrations induced in vehicle during travel on off-road or cross-country terrains is random and unpredictable, there is a concern to analyse the vibration response of chassis and chassis mounted structures is needed. Present work deals with vibration measurement and spectral analysis of a chassis mounted structure designed for off-road and commercial transport vehicles. The road profile on which the vibration measurement has been carried out includes paved road and cross-country terrain segments. The vibration measurement has been carried at three different vehicle speeds. Signal analysis procedure for the acquired test data is discussed. The chassis mounted structure under concern is intended to hold two shelters or containers. From the vibration measurement at critical locations, g-(RMS) and g-(peak) values for paved and cross-country roads have been found out. Power spectral density values have also been found on chassis and structure for the same transport situations. Major inferences include the evaluation of minimum and maximum g-values (peak & RMS) on chassis and chassis mounted structure. Power spectral density graphs are constructed from which the dominant frequency for both road profiles is found out

Present work deals with the process of determination of strain in a structural member under intense load for a typical Indian truck. Characteristics of mechanical strain at various locations on the structure are assessed. Strain gauge selection along with process of locating significant positions for strain measurement on the structure is described. Experimental process is employed for strain measurement. From the experimentation carried on the structure, the results reveal that the tri-axial stresses are dominant over bi-axial and uni-axial stresses at critical points on the structure. Contemporary data acquisition systems are utilized to acquire the strain signals. Computer simulation is carried out to have perception of the behavior of the structure under consideration. Static and Dynamic strain measurement is carried out at constant speeds on various tracks. As there are no assumptions involved in measurement like theoretical modeling and analysis, the experimental method provides the actual strain/stress values at the selected locations. Locations have been selected at cross-members where they are supported at the longitudinal members. As the stresses at these locations are not unidirectional, rosettes have been used to acquire strain in three directions. Linear strain gauges used at locations on longitudinal members.

Modeling and finite element analysis for a casting defect in thin wall struct...Dr.Vikas Deulgaonkar
The casting of pump impeller blades is a difficult operation due to its thin wall structure. In the casting process for thin wall impeller structure, the prediction of shrinkage defect is a one of the important issue and failure of such thin wall structure is a commonly encountered problem. The non-uniform heat transfer rate is the main cause of such failure. The uniformity of heat transfer rate may enhance by placing the runner at appropriate position and riser based on the geometrical attributes. The flow of liquid metal and its solidification has time based temperature variation, shrinkages and porosity distributions in such structures. An attempt is made for the analysis of optimization in the placement of runner and riser through this experimentation. The experiment contains the analysis of finite element simulation of fluid flow and solidification of metal execution at various temperatures, prediction of shrinkages based on the geometry of the casting and flow curvature and porosity distribution. This work also focuses on the prediction of casting defects in aluminum thin wall pump impeller structure using commercially available software (ANSYS-FLUENT). The experimental validation of the simulation result is also done to confirm the same.

The present work depicts mathematical behavior of a vehicle mounted platform/frame integrated with chassis structure in terms of plane stresses and plane strains for non-uniform loads. The load type considered in present work is concentrated load for which the mathematical model is formulated. A different type of combination of longitudinal and cross members in platform/frame design is formulated. The dimensions of platform members are determined using IS standards. After analysis of all possible combinations of longitudinal and cross members present design is anticipated. Section properties of longitudinal and cross members of the platform are determined & deduction of bending stress and shear force based on the load pattern are the fundamental steps in design and analysis of platform structure. The peculiarity of this analysis is the calculation of combined section modulus of three members. These are evaluated by excel programs developed indigenously.
Chassis mounted structures provide a levelled base to the transport vehicles intended for on-road and off-road driving. These structures acts as cushioning elements to sophisticated cargos like intelligent tracking systems placed in shelters’ closed environment. These structures need sufficient strength and rigidity to withstand the load variations arising from tire-road interactions during rough road travel. Such structures need special attention during the design phase itself in order to improve the specified payload carrying capacity with optimized dimensions. Present paper focuses on formulation of a specialized structure mounted on chassis intended to carry shelters. A scaled prototype is manufactured and tested for different grade-load combinations. This is done through experimental strain measurement and analysis of the results. The data is acquired for nine different load magnitudes and is categorised into three sets as low, moderate and high magnitudes. Interrelation between the stress/strain values acquired during each load and gradient state is developed. The structure behaviour is hypothesized through the gradient strain measurement outcomes. Major design concerns include the spacing & orientation of cross-members, load locations on the structure and the road profiles. Cross-country and rough road terrain behavior of the structure is attempted in present work.

Present work deals with the failure analysis of fuel pump in transport utility vehicles. The fuel pump assembly failed at 70536km. Various types of failures in pump and its different components are analyzed. Failure mode and effect analysis (FMEA) of the acquired data has been carried out. The pump components with substantial contribution in failure are determined using risk priority number analysis and the failure causes are postulated. Using scanning electron microscopy (SEM) for pump parts as rollers and cam plates the types failures are observed. Presence of water in fuel tank indicated the reason for rusting of bottom surface of tank. Pitting failure due to rust particles has been identified in pump parts after SEM observations. Energy Dispersive Spectroscopy (EDS) of pump parts has also been carried out to identify levels of unnormalized constituent elements responsible for failure. From EDS presence of oxygen responsible for oxidation reaction with iron is identified. Significant percentage of oxygen at different locations indicated the presence of moisture in the system. Remedial measure to avoid pump failure has been suggested in present work.

Present work deals with the design and analysis vibration characteristics for transport utility vehicle. The transport utility vehicle is designed using automotive industry standards. The dynamic behaviour of vehicle depends on the selection of overall dimensions, wheel base, track width, overall height and width that are decided using central motor vehicle rules. The selected dimensions for vertical and horizontal pillar members of the transport bus are modified to enhance the strength, stiffness and stability of the superstructure during travel. This increased stability enhances the ride comfort and passenger safety. Analysing the effect of utilizing manual meshing in complex areas of a transport utility vehicle for vibration analysis and passenger ride comfort has also been carried out. Modal analysis to evaluate the dynamic behaviour of transport utility vehicle model is also carried. Further with the use of finite element analysis deflection vehicle structure is evaluated. The outcomes from the analysis are compared with the behaviour of chassis mounted platform in dynamic conditions and are found in close correlation. The vehicle structure behaves as a single entity in dynamic situations, so surface model is prepared. Element selection for the finite element analysis is carried by considering plane stress condition. Two-dimensional quadrilateral shell elements are extensively used for meshing of the computer model of the vehicle structure.

An investigation of structural integrity of chassis mounted platform subjecte...Dr.Vikas Deulgaonkar
The present work deals with the investigation of strength of a specialized chassis mounted platform/structure designed to carry concentrated load. This work deals with the mathematics behind braking through shear and bending diagrams analysis processes. The perceptible loading case in the present analysis comprises braking load and its effect on the platform/structure by usage of simple shear force & bending moment diagrams. These diagrams reveal the distribution of shearing force during braking for typical Indian truck. Present analysis accentuates on the design stage aspects of the platform as this research is a step in doctoral study. Effect of load during braking for an atypical type of combination of longitudinal and cross members in platform/frame design is formulated. This paper provides a new technique for computation of strength using shear and bending diagrams. Peculiarity of this analysis is the usage of combined section modulus of three members for computation of stress.

WORK-PIECE DESCRIPTION
The work-piece considered under the project is the Pinion used in Indian Railways’ transmission system, which is
press fitted in the tapered hole. After due time, the pinion needs to be taken out for timely maintenance. The Gun drills are
used to pass pressurized fluid in the tapered section. This function allows the pinion to be easily removed from the system.
Figure 1: Pinion Work-Piece Figure 2: Cross-Sectional View of Pinion
The main motive of the project is to design, analyze and manufacture a ‘Jig and Fixture’ for drilling two holes on
the circumference for proper flow of lubricant in the gear.
CAD MODELING
In present work, considering the length to diameter ratios for circular components and length to respective
dimension ratio for non-circular components, solid modeling technique is used. To avoid complexity during finite element
analysis, the computer aided model is prepared using extrude, pocket, pad, hole and chamfer commands. For Computer
aided design of the components, use of CATIA V5-R21 is done. The computer aided models are shown in figure.
Figure 3: Bracket Figure 4: Center Pin
All the components designed for the Jig-Fixture assembly is done, keeping in mind the space constraints.
Numerous permutations of dimensions were carried out and finalized on the basis of force analysis, cost and dimensional
constraints.

FINITE ELEMENT ANALYSIS
Material Selection
Jig and fixtures are made from a variety of the materials. After studying properties, availability and cost of
materials, we have come to the conclusion that MS is the most suitable material for jig and fixture. MS is selected because,
it shows good resilience against deformation, and also it is more economical and easily available when compared to other
materials like Cast Iron and Carbon Steel. MS can be easily hardened with methods like carburizing, case hardening,
Shot peening etc. Properties of MS are given below in the table.
Table 1: Mechanical Properties of Mild Steel
Sr. No Property Value
1. Ultimate Tensile strength 440 MPa
2. Yield strength 370 MPa
3. Modulus of Elasticity 210 GPa
4. Density 7860 kg/m3
5. Poisson’s Ratio 0.290
6. Hardness 131 BHN
Meshing And Mesh Quality Check
Very first step in Analysis is meshing, which means discretization. The component is divided into finite number
of small elements. This helps in converting the problem with infinite DOF’s into finite DOF’s. With the use of Hypermesh
13.0, meshing operation is done on Bracket and Center Pin. Dimensions of the model i.e. length(515mm), breadth(250mm)
and height(200mm) are compatible, also the stresses are induced in all the 3 dimensions. Hence, 3-Dimensional solid
meshing is done and parabolic tetra elements are used. Firstly, 2-Dimensional meshing is performed on the surface and
then they are converted into 3-Dimensional tetra elements.
Primary mesh size is assumed as the smallest dimension of the object, and iterations were conducted with
changing primary mesh size. Mesh size is selected with the help of Convergence criteria. The values of stresses,
displacement and time taken for solving with different mesh sizes has been tabulated, and the optimum mesh size of 2 mm
is selected having less deviation in stress & deformation values than other mesh size’s results, along with optimum solving
time.

Boundary Conditions
Application of loads on intended portions and fixing the bolted and fabricated areas is known as applying
‘Boundary Conditions’. This is the most important step after meshing, because the results depend on the value and position
of loads and constraints. Forces are evenly distributed over the nodes in the area, where the force is acting in reality.
For Center pin, we have constrained the threaded portion and applied the hand force of 150N on the handle, a
vertically downward force of 74.4 N which is the self-weight reaction force of pinion on the front taper portion.
For bracket, the bolting positions are constrained, and a force of 3kN which is the maximum load bearing capacity of
thread is applied on rest buttons.
Hand force = 75N on each end.
Weight of Pinion = 180N
Vertical reaction Force of Pinion = 74.4N
Horizontal force acting on Bracket = 3kN
Figure 8: Boundary Conditions on Center Pin Figure 9: Boundary Conditions on Bracket
FEA Analysis
The model is solved in Optistruct solver of Hypermesh 13.0 using applied boundary conditions. After solving the
problem, next step is known as post processing. In post processing, the results are shown in user understandable format
i.e. Stress induced at the object is shown in the form of color bands, which shows how uniformly the stress is distributed
and at which point, the magnitude of stress or deformation is maximum that shows where the possible failure can occur.

RESULTS AND CONCLUSIONS
The results achieved from CAE analysis are compared with the calculated results for validation purpose.
CAE results are little bit deviated from the actual results, due to various parameters as shown below in the table.

2 Center Pin 39.09 370 0.030 2
After analyzing the critical components in our model, we came to know that the values of stresses induced are less
than the yield strength of the material, and also the values of deformation are in the range of few microns, which indicates
that it will not affect the accuracy in the Drilling operation and can fulfill the purpose of precisely drilling the holes in the
pinion. Simulation of impact of load and its consequences are observed using the Hypermesh 13.0. The obtained results
were well within the limits according to safety and failure aspects. Therefore, it can be said that the design is safe
and fool proof.

ABSTRACT
The manufacturing industry caters the range of products to satisfy the ever changing market needs.
To overcome the increasing production demands, the industry implies various techniques. We need a technique for
increasing the production of drilling two holes on a Railway Pinion, improve the quality of product and reduce the
operation time. This project aims to design the Jig and Fixture for the same. The 3-dimensional Computer Aided Model
of the components is made using CATIA V5-R21 software. To study the behavior of component, simulation is carried out.
Preprocessing of the CAD model is carried in Hypermesh software. Boundary conditions are applied using physical
situations of the components. Finite element analysis of the components is done, and the results obtained are compared
with the theoretical analysis and also with the available literature. The stresses and deformations are found within desired
limits. Using FE analysis, the parts are manufactured and assembled.

INTRODUCTION
For any manufacturing unit, productivity is of great concern to maintain the profitability and sustainability
of the unit. Various factors govern productivity of the manufacturing unit, which includes but not limited to skilled
man-power, quality of products, availability of machinery and raw material i.e. inventory, human factor, working
environment and many more. However, with the availability of modern machinery, the heart of production unit has
become the design of Jig and Fixtures. These are the sole components, which keep on changing the available
machinery as per product dimensions and shape. One such case is considered in present the work. The objective is
to minimize the cycle time and simplify the drilling operation for Radial drilling machine. This is done using
classical/theoretical approach. Present literature reveals the use of CAD/CAE and experimentation techniques to
validate the classical design.
