Abstract: Today’s industry demands versatile, efficient, and cost effective equipment while at the same time providing more flexibility along with significant savings through increased productivity. Most of the researcher’s did work on static analysis of I-section for by using Analytical and Software basis. One of them ISMB-250 beam are taken for 0.5 ton capacity of Floor mounted jib crane. The purpose behind the design of I-section cantilever beam for 0.5 ton capacity of Floor mounted jib crane is that to reduce the cost, make more efficient and to provide more flexibility. Hence instead of ISMB-250 beam, ISMB-200 beam is selected for reducing cost, more efficient and more flexibility. To check behavior of ISMB200 beam for Floor mounted jib crane in the form of stresses & deformation using Analytical, ANSYS and Experimental (Strain gauge technique). The additional part in this project is Modal analysis. The purpose of modal analysis is to measure the dynamic vibration characteristics such as (Natural frequency, deflection) by using Analytical and Experimental (FFT Analyzer). The differences error between Analytical and FEA values of stress and deformation in the form of percentage are 18% and 8%. Similarly the stresses error difference between Analytical and Experimental are approximately near to 4%.  The difference error between the natural frequencies is varying from 4% to 18%. From observing the below results, for lifting 500kg load the optimum I-section beam for Floor mounted jib crane is ISMB200. Due to this selected beam cost is reduced by 30% as compare to existing (ISMB250 beam). Future scope in this project is to perform harmonic response analysis using experimental and numerical.

Keywords: Design, structural analysis, modal analysis, strain gauge technique.

Abstract: Condition based monitoring is a manufacturing active tool to predict and find out the causes of defect in any machine. Generally in industry almost all machines have rotating components and they rotate about their true axis, but due to difficulties in manufacturing, inspection and material handling it is very difficult to manufacture components with true length. So during manufacturing every process is carried out with given tolerance and some time it is very difficult to achieve that and due to this some defects are always present with components. In actual, machine working with some vibration may lead to breakage of mechanical linkages or component, so it is very important to find out that cause at early stage. In industry, flange coupling is used to transmit power and it has been found that rigid flange coupling is more prone to vibration. The objective of this paper is to review and summarize this literature to provide an extensive and good reference for researchers to utilize. The overview of the rigid flange coupling is introduced with existence problem and solution for them. The different parameter which affects vibration of rigid flange coupling and their results with FFT, Mathematical Modelling, ANSYS Workbench etc. are also reported.

Keywords: Misalignment, Coupling, FFT, Vibration.

Abstract: In this paper detecting the faults in the railway infrastructure with the help of wireless sensor networks can be achieved. Nowadays Sensor technology can be used widely and the sensor devices have become cheaper. Wireless communication such as GSM-R, Satellite, GPRS is used for transmitting and receiving the signals. Railway infrastructure includes tracks, bogies, wheels can be monitored through condition monitoring. Defects can be identified using acoustic emission sensor and PIR sensor. Acoustic emission sensor is used for detecting the cracks on the tracks and PIR sensor is used for detecting the presence of human and animals on the track. Automated monitoring achieves accuracy of the fault and has a less cost, low power consumption and less analysis time. The exact location of the fault can be identified by the sensors without any human inspection so that people time can be saved.

Abstract: Transportation has become an integral part of people’s day to day life. At certain times, in large countries like India, people are forced to travel long distance from their work place to their place of residence. People with upper limb amputation and hands have difficulties in travelling and cannot travel these long distances. They use devices such as wheel chair, crutches and artificial limbs for mobility. These however cannot be used for long distance outdoor transportation Therefore, the aim of this project is to design and fabricate ‘Foot operated system’ for armless people.

The Foot Operated Steering mechanism is a mechanism controlled by foot or both the feet in order to steer the vehicle in the desired direction .This system consists of a steering which can control brake along with steering. The main objective of the project is to design a foot operated system for handicapped people.

Keywords: Foot controlled Handicapped, Steering system.

Abstract: This paper analyses the steady state performance characteristics of a rigid rotor mounted finite oil journal bearings considering pressure depended viscosity effect including elastic distortion on the surface of bearing liner. The theoretical analysis is intended to show how the effect of elastic distortion on the journal bearing performance for three-dimensional bearing geometries. The deformation equations for bearing surface will be solved simultaneously with hydrodynamic equations considering variable viscosity. It has been observed that load carrying capacity decreases with increase of the elasticity parameter of the bearing liner for loaded bearings and load carrying capacity increases with increase of the viscosity parameter.

Keywords: Journal bearing, surface deformation, viscosity, attitude angle, eccentricity ratio, Reynolds equation.

Abstract: The effect of fluid inertia is generally neglected in view of its negligible contribution compared to viscous force in the analysis of hydrodynamic journal bearings. The fluid inertia effect cannot be neglected when the viscous force are of the same order of magnitude and then the fluid inertia effect is to be taken in the analysis when the Modified Reynolds number is around one. Since no machining surfaces are perfectly smooth so the assumptions of smooth surfaces can no longer be employed to accurately predict the performance characteristics of journal bearing systems. This theoretical work analyses the combined influence of surface roughness and fluid-inertia effects on performance characteristics of hydrodynamic journal bearing. The average Reynolds equation that modified to include the fluid inertia and surface roughness effect andis used with appropriate boundary conditions to obtain pressure profile in the fluid-film region. The solutions of modified average Reynolds equations are obtained using finite difference method and appropriate iterative schemes. The effects of surface roughness parameter, roughness orientation, and roughness characteristics of opposing surfaces including fluid-inertia effectssimultaneously on circumferential fluid-film pressure distribution, load carrying capacity of the bearing are studied. The steady state bearing performance analysis is done through parametric study of the various variables like modified Reynolds number, eccentricity ratio, slenderness ratio, attitude angle, surface roughness parameter, surface pattern parameter. The variation of bearing load carrying capacity, attitude angle, end flow, friction parameters has been studied and plotted against various parameters.

Keywords: Modified Reynolds number, slenderness ratio, attitude angle, sommerfeld number, eccentricity ratio, journal bearings, fluid inertia, roughness pattern and roughness parameter.
