    By M. Karthe *, S.C. Prasanna

    Abstract

    Increasing of automobiles in the world, proliferates the harmful pollutants in the atmosphere. The catalytic converter is introduced to reduce antagonistic exhaust emissions from the automobiles. The emissions of concern are unburned or partially burned hydrocarbons (HC), carbon monoxide (CO), oxides of nitrogen such as nitric oxide and nitrogen dioxide (NOX). Catalytic converter incorporates a precise combination of precious metals platinum, palladium and rhodium. It decline the emissions through oxidation and reduction reactions. For diesel engines, catalytic converter is used to control HC and CO, but reduction of NOX emissions is poor because the engine runs lean, in order to avoid excess smoke. Although, various emission control techniques are in progress, the emission level are always in higher rate. While more efforts persist to find cheaper alternatives, we done a project by using barium chloride (BaCl2), an alkaline earth metal and zirconium oxide (ZrO2) are mixed together in the definite ratio and feed into the catalytic converter setup by spray pyrolysis methodology. As a result, the reduction of emission level as well as cost is acquired. This experiment will enhance the pollution free environment.

    By R.Velavan*, S. Nandhakumar, P. Vijayakumar

    Abstract

    Electric discharge machining (EDM) is widely adopted unconventional machining practice, which relies on thermal energy produced from the spark in-between the electrode and the clamped workpiece. In this EDM, the removal of the material is accomplished by continuous discrete discharges between anode and the cathode. The efficiency of the EDM purely relies on the material from which electrode and machining workpiece is made and combined with the dielectric media used. A good selection of electrode can decrease the machining cost. This paper deals with die-sinker EDM with brass as electrode to improve performance factors and cost reduction in machining with EDM. From the experimental results, it is found that a brass electrode give comparatively a better results for certain characteristics but the cost became a worrying factor for machining when the brass electrode material is utilized. So with the intention of balancing the cost and input parameters, brass electrode is experimented with nano powder mixed dielectric medium. It is concluded that the addition of nano powder in the dielectric medium reduces the surface roughness considerably while improving the machining performance.

    By S.Nishanth1, P.Praveen2, L.Ragunath1

    Abstract

    Machining fixtures are most importantly used for holding the workpiece while doing machining operation. Apparatus design means the situating of fixing of the components, for example, locators and clamps. To make sure that the workpiece is made by indicated measurements and resistances, it must be suitably found and clamped. Minimizing workpiece distortion because of clipping and cutting strengths is fundamental to keep up the machining precision. A perfect apparatus configuration displays minimum deformation while machining. This research work has been done to find the desired fixture to minimize the distortion of elasticity of the workpiece created by the fixing and machining strengths following up on the workpiece while machining. This will be accomplished by choosing the perfect number of fixture components with correct positions. To find the optimum location of fixture elements locator and clamp positions are varied with the basic 3-2-1 layout. Then the corresponding moment values are found out by Hybrid Differential Evaluation Krill Herd (HDEKH) In HDEKH objective function for minimization of moment is formulated. The position of fixture elements which gives minimum moment is the optimum fixture layout. Then the deformation of work piece for the optimum fixture design has got from MATLAB.

    MECHANICAL BEHAVIOUR OF VINYL ESTER BASED HYBRID COMPOSITE REINFORCEMENT WITH SISAL/PROSOPIS JULIFLORA/E-GLASS FIBERS

    By T. Keerthi Vasan*. S. Padmavathy, G. Sharmila Devi, S. Nandhakumar

    Abstract

    Natural fibre reinforced polymer composites became more attractive due to their high specific strength, light weight, and environmental concern. The incorporation of natural fibres with the combination of E-glass has gained many industrial applications. Naturally fibres are of little use unless they are bonded together to take the form of structural element that can carry load. Hence the combination of fibres and the matrix can have high strength and stiffness yet they have low density. The fibres used here are Sisal, prosopis juliflora and E-glass with Vinyl Ester as the matrix. The composite material has different mechanical properties. The arrangement of fibres is anisotropic which means that the body has different mechanical properties in different directions. The material is cut in the American Society for Testing and Materials (ASTM) standard and the mechanical properties such as Tensile, flexural and impact strength are determined. The main objective of the paper is to make a composite material which is to be incorporated in replacing the conventional steel leaf spring and in utilizing the fibre which pose threat to the environment.

    COMPARITIVE ANALYSIS OF PLAIN AND HERRINGBONE GROOVED JOURNAL BEARING UNDER THE HYDRODYNAMIC LUBRICATION CONDITIONS

    By Karthi. R.R., Dhanabalan. S.

    Abstract

    Journal bearings are important machine elements which are used for supporting the shafts. They are used in various applications like gas, oil engines, aircraft, automobile engines, machine tools, and turbines, etc. One such application is two- wheeler oil pump to which the paper is concerned with. The plain journal bearings are used in the oil pump to support the radial loads. Though the load carrying capacity of the PJB is higher, it has some common problems like low radial stiffness, instability in concentric operations, hydrodynamic pressure losses, etc. To overcome these problems, a beveled-step herringbone grooved journal bearing can be used. This is because it has higher radial stiffness, stability in concentric operations, hydrodynamic pressure recovery in divergent zone, increased pumping capacity, etc. Thus, by replacing the PJB by HGJB, the problems in the oil pump can be rectified and the oil pump works more effectively than before. ‘C’ and ANSYS are the tools used for proving the effectiveness of HGJB over PJB. ‘C’ program is used to determine the maximum hydrodynamic pressure where ANSYS is used to determine the maximum stress developed in the journal bearing due to the hydrodynamic pressure. By observing the results of PJB and HGJB, their working eccentricity ratios are determined. This itself would provide information about compensation of radial stiffness, load carrying capacity, pressure recovery, etc.

    Abstract

    This contemporary analysis on the optimization of mechanical performance of hybrid bio particle infused natural coir polyester composites using Quadratic-Conjugate Global criterion method. The rice husk particles and groundnut shell particles are the bio particles which are used with natural coir fibers as particle reinforcements in polyester matrix. The mechanical performance such as tensile and impact of coir polyester composites bio particulated with rice husk and groundnut shell particles were evaluated for the introduction of a new range of polymer composites with natural fibers and particles. The interlaminar bond between the reinforcements and matrix of the composite materials were evaluated using SEM images. The quick collapse of natural fibers due to cracking of matrix in the polymer composites was solved in this research by including bio particles which strengthens the matrix. The most favorable fabrication considerations for enhanced mechanical properties were predicted using QuadraticConjugate Search procedure. The efficiency of this Quadratic-Conjugate search was endorsed on the achieved fabrication parameters by using confirmation trials.
