DESIGN AND STRUCTURAL ANALYSIS OF BRAKE DISC BY VARYING BRAKE PRESSURE

Abstract

A brake is a device utilizing which artificial frictional resistance is applied to the moving elements to stop the machine\'s motion. Various forces are to be considered while applying the brake for the braking effect\'s effective performance. Initially, the driver\'s force on the brake pedal is multiplied as per the pedal ratio, and this multiplied force is carried to the brake pads in the disc caliper. As a result, the frictional force is developed at the disc surface\'s contact area and brake pads. This developed frictional force obstructs the motion of the vehicle. The magnitude of the frictional force developed at the disc surface\'s contact surface, and brake pads basically depends on the force developed at the brake pedal due to the pedal ratio. In this paper, brake performance is studied under varying brake pressure. This brake pressure depends upon the pedal ratio. Along with the theoretical analysis, software like ANSYS is used to determine the disc\'s sustainability under varying loads obtained by varying force applied on pedal and pedal ratios.

FABRICATION OF RECORD AND PLAY ROBOTIC ARM USING 3D PRINTER

Abstract

As we aware of the thing that jobs which are repetitive are in the favor of killing the human creativity. In the long run world is getting better day to day. But some jobs are still stuck in the same accent. Due the many factors such as higher machinery cost, high availability of labor at low capital, lack of availability of modern equipment. Robots have the potential to replace the humans at the manufacturing line. They complete the assigned work in the less time. Functionality of these robots is purely based on the instructions given to it in the form of program. Robots are highly reliable and works efficient they keep their high point in maintain the accuracy and precision. They can function round the clock and they are not relay on the seasons. In the broad view they help us to think differently by reducing the physical work, hence they are perfect for line and repetitive jobs. On the other hand they are high on cost, and their production craves for the highly skilled people. These robots are difficult to manufacture since it require greater amount of precision. To overcome such problems and to save the material to decrease the cost a new manufacturing process need to be adopted. Additive manufacturing the term itself refers the process i.e manufacturing process in which material is melted to its melting point and joined to get the desired shape. In this kind of manufacturing process only one machine is enough to get the life for a design. Hence they is need not have heavy machinery and number of machines for different functions. Robotic arm made out of additive manufacturing would reduce the cost and makes the manufacturing process a piece of cake to illustrate this and to study about the 3d printing and to draw out the challenges faced in such a manufacturing process we opted the design.

OPTIMIZATION RESISTANCE SPOT WELDING PARAMETERS BY TAGUCHI METHOD TO IMPROVE WELD QUALITY

Abstract

Almost a hundred years ago, the resistance spot welding process was introduced. Since then, in almost all industries that need to unite sheet metal parts together, it has found extensive use. Resistance spot welding (RSW) is commonly used in the car industry for its low cost, high speed, simple mechanism and automation applicability. In particular, its use is of great significance in the automotive industry, as each vehicle requires approximately 5000 spot welds in its assembly process. This project work discusses the optimization of different resistance spot welding parameters in order to increase the efficiency of welds. The experimental studies to be carried out for the joining of two DPs under different welding power, welding current and welding timeIn this investigation the quality characteristics (direct tensile strength and shear tensile strength) has been considered. D.P(dual phase) steel is used in this analysis as a sheet metal works piece. In order to extract the experiment data in a controlled way for Taguchi statistical analysis, L9 Orthogonal Array is to be used. In this study, three levels are considered for each process parameter. The experiments will be conducted as per the pattern of L9 Orthogonal Array. The optimum welding parameter combination was obtained by using analysis of signal to noise(S/N) ratio. Analysis of variance (ANOVA) is the statistical treatment most commonly applied to the results of the experiments to determine the percentage contribution of each parameter against a stated level of confidence The experiment results reveal that the most significant spot-welding parameters that are affecting the strength of the spot-welded joint both in 1.5mm and 2mm.The optimum spot-welding parameters were established, and they are confirmed by using validation experiments.

TIG WELDING PROCESS PARAMETERS OPTIMIZATION FOR STAINLESS STEEL MATERIALS USING REGRESSION ANALYSIS

Abstract

In today\'s manufacturing market, mainly quality and productivity play a significant role. Every manufacturing firm aims at producing a larger number of units within a short time. The experiments have been planned using the design of experiments and followed by regression analysis. The welding parameters used are Weld Current (I amps), Gas flow rate (FR L/min), and Root Gap (G mm). The effect of welding parameters, distortion (mm), and tensile strength (N/mm2) can be calculate, and the optimum welding condition can be determined to mitigate distortion and tensile strength. An L4 orthogonal array was taken for an experimental layout to analyze each parameter\'s effect on the welding characteristics and predict each weld parameter\'s optimal choice, such as weld current, Gas flow rate, and root gap. The impact of this parameter in Distortion (D) and Tensile Strength (TS) is analyzed. Optimization of welding parameters is valuable in terms of providing high precision and efficient welding for massive structures. Optimization of welding parameters is essential for a manufacturing unit to respond effectively to fierce competitiveness and increasing demand for quality products in the market. In the welding process, the optimization of weld process parameters is considered a vital tool for improving the output quality and reducing the overall production time.

IMPLEMENTATION OF DYNAMICALLY RECONFIGURABLE ARITHMETIC UNIT FOR VIDEO ENCODING

Abstract

The field of inexact figuring has become basic thought from the exploration assemble in the past couple of years, especially concerning diverse flag preparing applications. Picture and video pressure calculations, for instance, JPEG, MPEG, et cetera., are particularly engaging contender for estimated figuring since they are tolerant of registering imprecision in light of human vagary, which can be manhandled to recognize exceedingly control beneficial use of these calculations. Regardless, existing estimated structures commonly settle the level of equipment figure statically and are not adaptable to enter information. For example, if a settled rough equipment setup is used for a MPEG encoder (i.e., a settled level of figure), the yield quality moves tremendously for different info recordings. This paper tends to this issue by proposing a Re-configurable rough engineering for MPEG encoders that overhauls control use while keeping up a particular PSNR edge for any video. Trial comes to fruition show that our approach of capably adjusting the level of equipment figure in perspective of the info video respects the given quality bound (PSNR corruption of 5-20%) transversely finished different recordings while achieving a power assets of 13-18% over a standard non-approximated MPEG encoder design. Notwithstanding the way that the proposed Re-configurable rough engineering is displayed for the specific case of a MPEG encoder, it can be adequately connected with other DSP applications.
