ABSTRACT
Engine mountings are widely used in automotive to hold Engine with chassis.
Automobile industry regularly improving from many years with the efforts in
modification of the mechanical parts of vehicle in order to improve their performance.
The most effective way of increasing automobile mileage while decreasing emissions
is to reduce vehicle weight. Existing mount has scope of mass optimization in current
design. Finite element analysis of mounting will be done using Hypermesh and Ansys.
Ansys software will be used for topology optimization. Fixture will be designed for
mounting bracket on UTM. Experimental stress of mount will be measured using
strain gauge and applying corresponding loading through UTM. Validation for strain

vector from FEA & Experimental results will be done. Conclusions and future scope
will be suggested.

INTRODUCTION
1.1 Background:
In this automotive area the need for light weight structural materials is
increasing as there is a more focus on fuel consumption reduction and
improvement in decreasing the emission. The magnitude of production
volumes has traditionally placed severe requirements on the robustness of
process used in the manufacturing. The manufacturers have strong importance
on the cost has the demand for the component to improve the material
performance and to deliver these materials at low cost is the requirement.
In automobile sector the extremely competitive automotive business needs
manufactures to pay a lot of attention to traveling comfort. Resonant vibration
is from unbalanced masses exist within the engine body, this is causing the
designers to direct their attention to the event of top quality engine mounting
brackets so as to confirm that there is improvement in riding comfort. The
demand for higher play acting engine mount brackets should not be offset by
arise within the production prices and/or development cycle time.
In diesel engine, the engine mounting bracket is the major problem as there is
unthrottled condition and higher compression ratio and even there are more
speed irregularities at low speed and low load when compared to gasoline
engines. So due to this there are more vibration excitation. By this vibration
engine mount bracket may fail, so by optimizing the shape and thickness of
engine mount bracket we can improve the performance at initial design stages.
By some studies it is observed that brackets saved 38% of mass. Structural
optimization is an important tool for an optimum design; comparison in terms

of weight and component performance structural optimization techniques is
effective tool to produce higher quality products at lower cost.
1.2 Problem Statement
In this automotive era the need for light weight structural materials is
increasing as there is a more focus on fuel consumption reduction and
improvement in decreasing the emission. Currently, bracket contains excess
material, leads to increase in weight of the vehicle. Directly affects the mileage
and cost. In this thesis, modeling present bracket in CAD software and
analyzing it for induced stresses and deformation in CAE software. Then using
topology optimization material will be removed. Again, analysis will be done
on optimized model for stresses and deformation. It is also tested
experimentally and results were correlated it with analysis results.
1.3 Objectives
1. Modeling current bracket.
2. Analyzing for stresses and deformation.
3. Topological optimization for the model.
4. Analyzing for stresses and deformation.
5. Experimental testing and correlating results.
2. LITERATURE REVIEW
Umesh S Ghorpade, D.S Charan, Vinay Patil and Mahendra Giakwad [1], in
this paper they have designed engine mount bracket of a car and focused on to
determine natural frequencies of car engine mount bracket. They have considered the
three materials for engine mount bracket that is aluminum alloy, magnesium alloy,
gray cast iron when modal analysis is carried out, it is found natural frequencies of
gray cast iron is low which will prove more hindrance in vibration of engine mount
