Abstract

This paper presents a proposed and applicable optimization algorithm based on the evolutionary algorithm to solve an environemental and economic Dispatch (EED) problem. This problem is seen like a bi-objective optimization problem where fuel cost and gaz emission are objectives .in this method, the optimal Pareto front is found using the concept of corridor observation and the best compromised solution is obtained by fuzzy logic. The feasibility of this method is demonstrated using power systems with three generation units, and it is compared with the other evolutionary methods of Optimization Toolbox of Matlab in terms of solution quality and CPU time. The simulated results showed that the proposed method is indeed capable of obtaining higher quality solutions in shorter computational time compared to other evolutionary methods. In addition the other advantage is that our approach solve in the same time a unit commitment problem and it can used with n-generation units.

Paper Indexed : : 03.3005/041031035
International Journal of Computational Engineering Resaerch , Volume 4 ~ Issue 10 (October 2014)

Abstract

An axial flow compressor is one in which the flow enters the compressor in an axial direction (parallel with the axis of rotation), and exits from the gas turbine, also in an axial direction. The axial-flow compressor compresses its working fluid by first accelerating the fluid and then diffusing it to obtain a pressure increase. In an axial flow compressor, air passes from one stage to the next, each stage raising the pressure slightly. The energy level of air or gas flowing through it is increased by the action of the rotor blades which exert a torque on the fluid which is supplied by an electric motor or a steam or a gas turbine. In this thesis, an axial flow compressor is designed and modeled in 3D modeling software Pro/Engineer. The present design has 30 blades, in this thesis it is replaced with 20 blades and 12 blades. The present used material is Chromium Steel; it is replaced with Titanium alloy and Nickel alloy. Structural analysis is done on the compressor models to verify the strength of the compressor. CFD analysis is done to verify the flow of air

Abstract

The technological growth has a serious impact on security which has its own significance. The core objective of this project is to extract the facial features using the local appearance based method for the accurate face identification with single sample per class .The face biometric based person identification plays a major role in wide range of applications such as Airport security, Driver's license, Passport, Voting System, Surveillance. This project presents face recognition based on granular computing and robust feature extraction using Scale Invariant Feature Transform (SIFT) approach. The Median filter is used to extract the hybrid features and the pyramids are generated after the face granulation. Then, DoG pyramid will be formed from successive iterations of Gaussian images. By this granulation, facial features are segregated at different resolutions to provide edge information, noise, smoothness and blurriness present in a face image. In feature extraction stage, SIFT descriptor utilized to assign the intersecting points which are invariant to natural distortions. This feature is useful to distinguish the maximum number of samples accurately and it is matched with already stored original face samples for identification. The simulated results will be shown used granulation and feature descriptors has better discriminatory power and recognition accuracy in the process of recognizing different facial appearance.

Paper Indexed : :03.3005/041059062
International Journal of Computational Engineering Resaerch , Volume 4 ~ Issue 10 (October 2014)

Abstract

The hypoid gears are a subtype of bevel gears. Hypoid gears are similar in appearance to spiral bevel gears. They differ from spiral-bevel gears in that the axis of the pinion is offset from the axis of the gear. On observation the hypoid gear seems to be similar in appearance to the helical bevel gears. The main difference being that the planes of the input and the output gears are different . This allows for more efficient intermeshing of the pinion and driven gear. Since the contact of the teeth is gradual, the hypoid gear is silent in operation as compared to the spur gears.These gears are usually used in industrial and automotive application and hence the material used is a metal like stainless steel. A major application of hypoid gears is in car differentials where the axes of engine and crown wheel are in different planes.In this thesis, the impact of misalignments on root stresses of hypoid gear sets is investigated theoretically with FEA. An experimental set-up designed to allow operation of a hypoid gear pair under loaded quasi-static conditions with various types of tightly controlled misalignments is introduced. These experimental data is collected from journal paper. Structural analysis is done to verify the strength of the hypoid gear for alignment and misalignment.Software for modeling is Pro/Engineer and for analysis is Cosmos

Paper Indexed : : 03.3005/041063067
International Journal of Computational Engineering Resaerch , Volume 4 ~ Issue 10 (October 2014)

Abstract

Pin jointed structures are more regularly used because they are simple to design, relatively inexpensive to make, easy to construct, and easy to modify. A pin joint is a solid cylinder-shaped device, similar to a bolt, which is used to connect objects at the joint area. The pin can only transmit a force and has no ability to resist rotation. They can be 'fixed' structures such as frames, or they can be structures that move, more normally referred to as mechanisms. In practice pin jointed structures often use bolts which are tightened and therefore they can resist rotation to a certain extent. This type of joint connection allows each object to rotate at the point of joint connection. Most mechanical devices that require bending or opening typically use a pin joint. These joints can be welded solid or allow movement between the two connected objects. In this thesis, analysis is done on the E Glass and S2 Glass epoxy composite plate with two serial holes by varying distance from the free edge of the plate to the diameter of the first hole and width of the specimen to the diameter of the holes and also and the distance between center of two holes-to-hole diameter. Structural and Fatigue analysis are done using Cosmos.

International Journal of Computational Engineering Resaerch , Volume 4 ~ Issue 10 (October 2014)

Abstract

Text Mining can be defined as a technique which is used to extract interesting information or knowledge from text documents which are usually in unstructured form. Information Extraction (IE) and Knowledge Discovery from Databases (KDD) are both useful approaches for discovering information in textual corpora. Information Extraction concerns locating of specific terms in natural-language documents. Knowledge Discovery in Databases is the process of discovering useful knowledge from a collection of data. This paper provides an analysis on various emerging text mining framework and methodologies. This paper examines text mining frameworks such as DiscoTEX (Discovery from Text Extraction), RAPIER (Robust Automatic Production of Information Extraction Rules), EPD (Effective Pattern Discovery) and BWI (Boosted Wrapper Induction. This paper provides an analysis of various text mining frameworks and defines their benefits and deficiencies which are then taken into consideration for proposing a novel framework for text mining referred as RDIET. The proposed framework uses an automatically learned IE system to extract a structured database from unstructured textual corpus, and then mines the database for deducing interesting relationships using KDD tools. The proposed technique concentrates in achieving mutual benefits of IE and KDD. IE enables the application of KDD to unstructured textual corpora and KDD can discover predictive rules useful for enhancing IE performance.

Paper Indexed : : 03.3005/04102011015
International Journal of Computational Engineering Resaerch , Volume 4 ~ Issue 10 (October 2014)

Abstract

Gears are machine elements that transmit motion by means of successively engaging teeth. The stresses are developed when two gears are mated. Two spur gear teeth in action are generally subjected to two types of stresses. One is bending stresses which are developed by fatigue bending another one is contact stress causing contact fatigue. These two types of stresses may not get 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. This project investigates the various stresses and deflection developed in sun gear tooth of sun gearbox which is used in Snag Crane. In this study, perform the calculation for sun gear tooth to calculate bending, shear, wear & deflection using theoretical method.The model was created using modeling software and the analysis is done using ansys. Here the analysis is performed on the root fillet of the spur gear tooth. The analysis is done two conditions as circular root fillet and actual root fillet of a gear tooth. The results of the analyses from ANSYS are compared with the theoretical values. Comparison of ANSYS results in circular root fillet & actual root fillet also carry out. In addition to the project we are changing the material of the sun gear and comparing the results. In the addition of this project we are finding the contact stresses of the mating gears. The theoretical values which are formed from the Hertz equation are compared with the Fea values which are generate from ansys. For the analysis, steel and grey cast iron are used as the materials of spur gear. The results show that the difference between maximum contact stresses obtained from Hertz equation and Finite Element Analysis is very less and it is acceptable. The deformation patterns of steel and grey cast iron gears depict that the difference in their deformation is negligible.

International Journal of Computational Engineering Resaerch , Volume 4 ~ Issue 10 (October 2014)

Abstract

Fiber-reinforced thermoplastic polymers are the primary reasons for their use in many structural components in the aircraft, automotive, marine, and other industries due to their low density, high strength, high stiffness to weight ratio, excellent durability and design flexibility. They are now used in applications ranging from space craft frames to ladder rails, from aircraft wings to automobile doors, from rocket motor cases to oxygen tanks, and from printed circuit boards to tennis rackets. Their use is increasing at such a rapid rate that they are no longer considered advanced materials. Residual stresses in the composite plates are particularly important. They can lead to premature failure. Therefore, the characterization of the elasto-plastic response of thermoplastic composite must be carried out along the credible design processes for composite structures involving plasticity effects in the nonlinear behavior. In this thesis, residual stresses developed on Flouoro polymer laminated thermoplastic composite plates with central elliptical hole which is subjected to in-plane loading is determined by applying different loads. The effects of orientation angle of elliptical hole in the composite laminated plate under various in-plane loads, elliptical hole is rotated from 0° to 90° by 15° increments counterclockwise. Analysis is done in Ansys.

Paper Indexed : : 03.3005/04102021026
International Journal of Computational Engineering Resaerch , Volume 4 ~ Issue 10 (October 2014)

Abstract

Delamination is a mode of failure for composite materials. Modes of failure are also known as 'failure mechanisms'. In laminated materials, repeated cyclic stresses, impact, and so on can cause layers to separate, forming a mica-like structure of separate layers, with significant loss of mechanical toughness. Some manufacturers of carbon composite bike frames suggest to dispose of the expensive frame after a particularly bad crash, because the impact could develop defects inside the material. Due to increasing use of composite materials in aviation, delamination is increasingly an air safety concern, especially in the tail sections of the airplanes. In this thesis, the effects of delamination length on the stresses and natural frequency of symmetric composite beams are analyzed using Ansys software. The composite material considered is carbon fiber. Structural and Frequency analysis are done on the composite beam by varying the delamination lengths.

Paper Indexed : : 03.3005/04102027031
International Journal of Computational Engineering Resaerch , Volume 4 ~ Issue 10 (October 2014)

Abstract

Disc brake consists of a cast iron disc bolted to the wheel hub and a stationary housing called caliper. The caliper is connected to some stationary part of the vehicle like the axle casing or the stub axle as is cast in two parts each part containing a piston. In between each piston and the disc there is a friction pad held in position by retaining pins, spring plates. The passages are so connected to another one for bleeding. Each cylinder contains rubber sealing ring between the cylinder and piston Due to the application of brakes on the disc brake rotor, heat generation takes place due to friction and this temperature so generated has to be conducted and dispersed across the disc rotor cross section. The aim of this paper was to investigate the temperature fields and also structural fields of the solid disc brake during short and emergency braking with four different materials. The distribution of the temperature depends on the various factors such as friction, surface roughness and speed. The effect of the angular velocity and the contact pressure induces the temperature rise of disc brake. The finite element simulation for two-dimensional model was preferred due to the heat flux ratio constantly distributed in circumferential direction. We will take down the value of temperature, friction contact power, nodal displacement and deformation for different pressure condition using analysis software with four materials namely cast iron, cast steel, aluminum and carbon fiber reinforced plastic. Presently the Disc brakes are made up of cast iron and cast steel. With the value at the hand we can determine the best suitable material for the brake drum with higher life span. The detailed drawings of all parts are to be furnished.

International Journal of Computational Engineering Resaerch , Volume 4 ~ Issue 10 (October 2014)

Abstract

A pressure vessel is a type of container which is used to store liquids or gases under a pressure different from the ambient pressure. Different shapes of pressure vessels exist but most generally cylindrical and spherical shapes are used. Spherical vessels are theoretically 2 times stronger than cylindrical ones but due to the manufacturing difficulties, cylindrical ones are generally preferred in the industry. Mostly the pressure vessels are thin walled but here we are generating multi layered wall. In this project we are designing spherical pressure vessel by using pro-e and the analysis is done by using ansys. Here two models are generated one is solid walled which is regularly used and another one is multi layered pressure vessel. And the analysis is done on the two models by changing the actual material with the composite material. The results are compared actual solid model with the multi layered pressure vessel and the comparison further extended to find the better material for that the actual material results of the model is compared with the composite material results. By the comparison we may find better design and the design proposed to the company.

Paper Indexed : : 03.3005/04102036040

Abstract

Rolling loss or rolling resistance is an ever important property for the tyre and automotive industries because of its practical implication. The tyre rolls under a load, it deforms. The load presses down on the tyre and squashes it against the road. As the tyre turns, the squashed part comes off the road and returns to its original shape while another part of the tyre gets squashed. The sidewalls of the tyre flex over and over again, close to 500 times per minute at highway speeds. And, the tread goes from a circular to a flat shape and back to circular again there are some practical things that can reduce deformation and heat. Inflation pressure has an effect. Underinflated tyres deform much more, get much hotter, and cut fuel economy. So properly inflated tyres save fuel by reducing rolling resistance. Fuel consumption and tyre rolling loss in all types of automobiles have become increasingly important because of adverse environmental effects and economic costs. If rolling resistance is reduced because of better tyre maintenance, consumers may end up spending less on tyres, because properly inflated tyres will have longer wear in addition to providing better fuel economy. In this thesis, the effect of rolling resistance on fuel consumption of radial passenger and truck tyres is discussed. A possible method of optimizing fuel use by adjusting the tyre load/pressure Conditions will be suggested. All these estimates will be obtained for radial tyres. Finite element analysis is done on the tyre by applying tyre load and inflation pressure. The investigations are made on two tyre models of automobile cars Skoda Rapid and Ford Classic. Modeling is done in Pro/Engineer and analysis is done in Ansys.

Paper Indexed : : 03.3005/04102041048
International Journal of Computational Engineering Resaerch , Volume 4 ~ Issue 10 (October 2014)

Abstract

An air-drawing model of polymer melt blowing process is established and solved by introduced the numerical computation results of the air jet flow field of dual slot annular die. Meanwhile, the model is also verified by the experimental results obtained with our university's equipment. The influence of the density and the specific heat capacity of polymer melt at constant pressure changing with polymer temperature on the fiber diameter are also studied. The predicted fiber diameters tally with the experimental data well. The effects of the processing parameters on the fiber diameter are further investigated in this paper. We find that a lower polymer throughput rate, a higher polymer melt initial temperature,a higher air initial temperature, and a higher air initial velocity can all produce finer fibers. The results show the great perspective of this research in the field of computer-assisted design (CAD) of melt blowing process and technology.

Abstract

Leaf springs are one of the oldest suspension components they are still frequently used, especially in commercial vehicles. The commonly used leaf springs in the vehicle suspension system are subjected to millions of varying stress cycles leading to fatigue failure. A lot of research has been done for improving the performance of leaf spring. Here in this project also we did an attempt of designing hybrid suspension system which was used in autos by using that concept of designing we designed a hybrid leaf spring. For this thesis we took Tata ace auto leaf spring as a reference and designed it by using modeling software. In the analysis we used ansys package and the results are compared with the hybrid suspension system for the same load. The main objective of the project is that to increase the load capacity of the leaf spring from this project we are trying to achieve this and further suggestions are made by observing the results.The model was designed by using Pro-E and analyzed using Ansys
