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.

Engine mounting system topology optimization using FEA and

Experimental stress analysis Technique.

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
