Pages: 8 - 14
Landing gear failure is a high concern in the aviation industries. As per the Federal Aviation Administration reports, most of the aircraft failures take place at the time of take-off and landing of aircraft. Generally aircraft failures are related to its improper maintenance of landing gear and health monitoring check-ups. In this project work a tri-cycle landing gear shock absorber system model is selected and analyzed it in multi-physics domain, using AMESim software package. AMESim stands for Advanced Modeling Environment for performing Simulation of engineering systems. The software package provides a 1D simulation suite to model and analyze multi-domain intelligent systems, and to predict their multi-disciplinary performance. The various multi-physics domains considered in modeling are mechanical, pneumatic, and hydraulic. Each of the sub-components of these domains are modeled and checked for their output variables. Under the dynamic simulation, vertical loads, strut displacements and efficiency curves of the shock absorber are plotted for various sink velocities. MATLAB programming package is used to perform the mathematical functions to find the efficiency of shock absorber with the help of load and displacement curve plots. In the multi-physics dynamic simulation vertical loads with respect to time and strut displacement with respect to time are plotted. For the validation purpose these plots are tallied with an experimental plots and the plots are well matched. If there is any further iteration is going to conduct on the same model or similar model instead of doing experimental test one can do software analysis to get the results.

Mechanical Engineering
Year: 2017, Volume:4, Issue : 8
Pages: 18 - 24
Vibration is an oscillation wherein the quantity is a parameter that defines the motion of a mechanical system. The main causes of vibration are unbalanced forces in the machine, dry friction between the mating surfaces, external excitation, earthquakes, wind self-excited vibrations, misalignment of rotating shaft, looseness in rotating machinery, loose foundations and excessive bearing clearances, oil whirl in bearing. The harmful effects of vibrations are excessive stresses in machine parts and undesirable noise. Also due to high vibration there are looseness of parts and partial or complete failure of parts. This vibration phenomenon is used in some musical instruments, vibrating conveyors, shakers, vibrating screens, stress relieving. This vibration can be reduced by removing the causes of vibration, by vibration isolation. Also vibration can be controlled by using shock absorbers and by installing dynamic vibration absorbers. Using composite material also vibration reduce. Automobile suspension Leaf spring consist high vibration during motion. By binding the composite material to steel spring the vibration can be reduced. ANSYS software used for Finite Element Analysis for vibration analysis.

The connecting rod is an intermediate member between the piston and the Crankshaft. Its primary function is to transmit the push and pull from the piston pin to crank pin, thus converting the reciprocating motion of the piston in rotary motion of the crank. This thesis describe designing and analysis of connecting rod. Currently existing connecting rod is manufactured by using steel. In this drawing is drafted from the calculation. A parametric model of connecting rod is modeled using solidwork 2016software and to that model, analysis is carried out by using ANSYS 15.0 software. Finite element analysis of connecting rod is done by considering the materials, viz... forged steel. The best combination of parameters like Von misses stress and strain, Deformation, Factor of safety and weight reduction for two wheeler piston were done in ANSYS software. Forged steel has more factor of safety, reduce the weight, increase the stiffness and reduce the stress and stiffer than other material like carbon steel. With fatigue analysis we can determine the lifetime of connecting rod.

Pages: 51 - 57
Welding of aluminium poses a great challenge to get a sound proof joint as many problems are encountered during the welding. In view of above fact welding of 6 mm plate of 6061 aluminium alloy , it was decided to weld the 6061 aluminium alloy with different welding processes viz. Gas Tungsten arc Welding (GTAW) & Friction Stir Processing (FSP). This present work aims to demonstrate the TIG welded Friction Stir Processing ability and the emphasis is placed on the relations of the tensile properties and hardness. To improve welding quality of TIG welded Aluminium alloy (Al-6061 T6) with the Friction Stir Processing. Tensile strength and hardness value of TIG welded joint and TIG welded plus Friction Stir Processed joint is investigated. The welded specimens were subjected to tensile testing, hardness testing and microstructure study. Tensile results obtained from this study show that the average UTS value is 299 MPa for base metal, 85 MPa for the TIG and 125 MPa for TIG + FSP, hence showing 48% increase from the TIG welded joint. Hardness value of base metal comes out to be 74. The hardness value of TIG + FSP specimen comes out to be 72-74 which is almost similar to that of base metal that is 74 whereas in TIG specimen hardness value is 66-68 and hence there is improvement in the hardness value. Optical microscopic analysis has been done on the weld zone to evaluate the effect of welding parameters on welding quality and microstructure. Microstructure of TIG + FSP joint is very fine equiaxed recrystallized grained which is better than the microstructure of TIG joint which is column and is fineaxed.

A novel post preparing system for pressure antique diminishment. Our approach depends on representing this undertaking as a backwards issue, with a regularization that influences on existing best in class picture denoising calculations. We depend on the as of late proposed Plug and-Play Prior structure, recommending the arrangement of general reverse issues through Alternating Direction Method of Multipliers (ADMM), prompting a succession of Gaussian denoising steps. A key element in our plan is a linearization of the pressure decompression process, to get a detailing that can be improved. Likewise, we supply an exhaustive examination of this straight guess for a few fundamental pressure methodology. The proposed strategy is reasonable for various pressure strategies that depend on change coding. In particular, we show amazing increases in picture quality for a few driving pressure strategies.

Pages: 62 - 70
In the contemporary consequence, for proclaiming the crimes in forensic discipline voice of a person has become a paramount and utilizable evidence, but in our judicial system its consequentially has always been a matter of controversy because of the circumscriptions imposed by sundry factors in the process of identification like background clamour, channel variations, distortions etc. Forensic speech samples customarily differ due to the variation among the acoustic parameters in their recording mode and conditions, affecting the findings. In existing study, to see the nature and amount of variations in acoustic/ perceptual parameters due to transmute of recording media the voice recording of speakers were taken under different recording conditions. The perceptual cues are studied along with their utility in different conditions that the human subjects use to perceive differences in voices. In this study we solely rely in terms of frequency, pitch and energy on recorders concrete variations, to facilitate the process of recognition and will differentiate such features from speaker concrete acoustic parameters.
