OBJECTIVE

The main objective of project to avoid whirling vibration. The operating parameter of the composite as its control the properties of the composite material.

These is focus on the study of mechanical behavior of Aluminum metal matrix composite with varies composition of reinforcement particles of graphite or nanoparticles, Sic and Al2O3 composite produced by the stir casting technique. Different percentage of reinforcement is used. Tensile test, Hardness test and torsional test.

INTRODUCTION

A composite material is defined as a material system which consist of a

mixture or a combination of two or more different materials which are

insoluble in each other and differ in form or chemical composition.

Composite materials should comprise component materials that are congenital

with each other. In the field of high modulus composites, resin-matrix

composites find considerable interest is easy to fabricate into engineering

structures.

Two Phase of Composite materials.(i)Matrix (ii)Reinforcement.

Classification of composite materials:

1. Based on matrix material.

2. Based on material structure.

INTRODUCTION (Cont.…)

The major composite classes based on structural composition of the matrix are:

Polymer-matrix composites Metal- matrix composites Ceramic- matrix composites Carbon- carbon composites The composite gives indication of the combinations of two or more

materials in order to improve the properties of monolithic material for adjusting to global need for reduced weight, low cost,quality,and high performance in structural materials.

IDENTIFICATION OF PROBLEM

The passenger cars, trucks and vans should have the torque transmission capacity more than 3500Nm and the natural frequency must be higher than 6500 rpm to avoid whirling vibration.

In that the critical speed of shaft is inversely proportional to the square of the length.so that the vibration problem could be solve by increasing the length of shaft but its not permitted due to space limitations.

So that its only for manufacturers and manufacture the shaft in two pieces.

TYPE OF ANALYSIS

Static analysis of composite shaft Torsional analysis Dynamic analysis (modal)

STATIC ANALYSIS

A static analysis is used to determine the displacements, stresses, strains and forces in structures or components caused by loads that do not induce significant inertia and damping effects.

In static analysis loading and response conditions are assumed, that is the loads and the structure responses are assumed to vary slowly with respect to time.

MODAL ANALYSIS

The natural frequencies and the mode shapes are important parameters in the design of a structure for dynamic loading conditions. Modal analysis is used to determine the vibration characteristics such as natural frequencies and mode shapes of a structure or a machine component while it is being designed.

The natural frequency depends on the diameter of the shaft, thickness of the hollow shaft, specific stiffness and the length.

PRESENT CONCLUSION

The behaviour of Aluminium alloy (LM6) and Silicon carbide literature was collected and studied.

The finite element analysis is used in this work to predict the deformation of shaft.

The fabrication of the section will be done in the next phase. Fabrication of section will be based on the design created in the first phase.

The modeling and analysis of shaft is done by using ANSYS Workbench.

FUTURE WORK

The volume fraction (5%,10%,15%,20%) of aluminum alloy(LM6) and SiC with Alumina will be fabricate through stir casting technique.

The specimen will be evaluated by using Hardness test, tensile test, Torsional test and SEM/XRD.

The specimens are going to be prepared by liquid metallurgy method, the Anna University CEG campus, Chennai was identified to prepare casting of composite materials by stir casting method.

The testing is identified at Root India Pvt ltd, Ganapathi Coimbatore.
