Abstract: Electrochemical discharge machining (ECDM) is a non-traditional machining process that involves high-temperature melting assisted by accelerated chemical etching. In the present work, experiments on ECDM have been carried out according to designed experimental plan based on standard orthogonal array (L9) to identify the effect of electrolyte solution on material removal rate. In controlling the machining performance, such as material removal rate the signal-to- noise (S/N) ratio is performed to find the relative contributions of the main machining parameters, such as applied voltage, electrolyte concentration and inter-electrode gap. The non- conducting and highly brittle Soda lime Glass is used as a work-piece material and aqueous KOH and H2SO4 is used as electrolyte solution.

Abstract: Sloshing has widespread applications in many industries including automotive, aerospace, ship building and motorcycle manufacturing. The need for sloshing study is mainly to accept the challenge for transportation of partially filled tanker. The goal of sloshing simulation is first to study the sloshing pattern and then improve the tank design to reduce stresses on the tanker surfaces and optimize the baffle arrangements. In this work, simulation of the LPG in tank is studied and the design modification with baffle plate is considered to minimize the sloshing phenomena using ALE method. Also it is explained that there is strong need to analyze the sloshing phenomena in detail. Arbitrary Langrangian Eulerian finite element methods gain interest for the capability to control mesh geometry independently from material geometry, the ALE methods are used to create a new undistorted mesh for the fluid domain. In this work we used the ALE technique to solve fluid structure interaction problem

Abstract: A number of researcher projects have been conducted to determine which physical motion parameters are actually perceived by humans during vehicle operation and which are judged undesirable or poor on the basis of their intensity. All of these investigations have endeavoured to find the best possible correlation between driver evaluation and measured parameters in specific driving manoeuvres. These relationships are examined in greater detail in this work. In this way, it will be possible to describe objectively a large range of vehicle ride & handling properties, which in turn will generate continuous improvement in systematic methods for suspension development, and to apply these advancements toward satisfying demands for continued progress. The main objective of this work is to quantify automobile ride & handling characteristics and to do sensitivity analysis of various hardpoints of Independent ( Macpherson strut ) suspension and Semi independent ( Twist Beam ) suspension.

Abstract: Reliability based design is the methodology for finding designs that are characterized with a low probability of failure. Assessing reliability of projects during design phase reviews requires a critical look at equipment details to determine if reliability has been built into the design for meeting performance goals required by the project. Failure modes effect analysis (FMEA) is an analysis tool for evaluating reliability by examining expected failure modes to find the effects of failure on equipment or systems. Fault tree analysis (FTA) is a deductive reliability analysis tool for evaluating reliability driven by top level views of what will fail and searches for root causes of the top level event. FTA considers experience and biases such as "every time we build a plant for this product we have these types of failures—". FTA provides both reliability assessments and fault probability perspectives.

Abstract: Gear is one of the most critical component in a mechanical power transmission system, and most industrial rotating machinery. A pair of spur gear teeth in action is generally subjected to two types of cyclic stresses: bending stresses inducing bending fatigue and contact stress causing contact fatigue. Both these types of stresses may not attain their maximum values at the same point of contact fatigue. These types of failures can be minimized by careful analysis of the problem during the design stage and creating proper tooth surface profile with proper manufacturing methods. In general, gear analysis is multidisciplinary, including calculations related to the tooth stresses and to tribological failures such as wear or scoring. In this paper, bending stress analysis will be performed, while trying to design spur gears to resist bending failure of the teeth, as it affects transmission error. First, the finite element models and solution methods needed for the accurate calculation of bending stresses will be determined. Then bending stresses calculated using ANSYS, were compared to the results obtained from existing methods.

Abstract: The advanced composite materials such as Boron, Graphite, Carbon, Kevlar and Glass with suitable resins are widely used nowadays for automotive and other industrial applications especially for rotor applications because of their high specific strength (strength/density) and high specific modulus (modulus/density). Polymer matrix composites were proposed for light weight shafts in drivelines for automotive, industries. Present work is conducted to analyze the composite drive shaft which is used for four wheel rear drive passenger cars. Carbon/Epoxy and Carbon-Glass/Epoxy drive shafts are analyzed taking into consideration the dimensional proportionality.

Abstract:In today's industrial scenario huge losses/wastage occur in the manufacturing shop floor. This waste is due to operators, maintenance personal, process, tooling problems and non-availability of components in time etc. Other forms of waste includes idle machines, idle manpower, break down machine, rejected parts etc are all examples of waste. The quality related waste are of significant importance as they matter the company in terms of time, material and the hard earned reputation of the company. There are also other invisible wastes like operating the machines below the rated speed, startup loss, break down of the machines and bottle necks in process. Zero oriented concepts such as zero tolerance for waste, defects, break down and zero accidents are becoming a pre-requisite in the manufacturing and assembly industry. A fundamental component of world-class manufacturing is that of the Total Productive Maintenance (TPM), which has been recognized as one of the significant operation strategy to regain the production losses due to equipment inefficiency. TPM is the methodology that aims to increase both availability of the existing equipment hence reducing the need for the further capital investment. The aim of the paper is to study the implementation of the TPM program in an Indian manufacturing industry. Using JH-Check sheet, PM-Check sheet, One Point Lessons, empirical and comprehensive approach toward the methodology results proper implementation of TPM. After implementation of TPM on model machine, both direct and indirect benefits are shown to be obtained for equipment and employees respectively.

Abstract: Fresnel lenses of imaging and non imaging designs are one of the best options for solar energy concentration. Compared with imaging systems, non-imaging systems have the merits of larger accept angles, higher concentration ratios with less volume and shorter focal length, higher optical efficiency, etc. Therefore, non imaging design can offer the possibilities needed for a breakthrough of Fresnel lenses in commercial solar energy concentration, both in photovoltaic and thermal power conversion. Fresnel lens solar concentrators continue to fulfill a market requirement as a system component in high volume cost effective Concentrating Photovoltaic (CPV) electricity generation as well as steam generation. This paper reviews the possible applicability of Fresnel lens based concentrators for application in low pressure steam generation.
