Design and Fabrication of Shock Absorber Compressor Spring

This report contains the design, fabrication and performance analysis of a shock absorber spring compressor. The detailed data of the different parts was presented. The materials selected for each part, the reason for selecting that material and the design of the different parts of the shock absorber compressor spring was carried out. The manufacturing processes involved was presented. From the design it was established that deflection in the spring decreases with reduction in the stresses applied to the spring. The test result of the fabricated shock absorber compressor spring shows that the tool was very efficient in extracting the spring during the repair process with danger of harming the technician working with the tool.

Prediction of Surface Roughness and Optimization of Machining Parameters in Drilling Process of Aluminum Alloy Al6061

In this paper, an experimental research was conducted to investigate the influence of the tool diameter, spindle speed, and feed rate on the surface roughness in hole drilling process. The Box Behken experimental matrix that was used with 15 experiments. The Minitab 16 software was used to evaluate the experimental results. The analyzed results showed that the spindle speed was a parameter that has the most important influence on the surface roughness. The second factors that affect on the surface roughness was tool diameter. And, the feed rate was the factor that has smallest effect on the surface roughness. The interaction factor between the tool diameter and the feed rate has the largest degree of the influence on the surface roughness, the second interaction factor that influenced on the surface roughness was the interaction between the diamter and the spindle speed. The interaction between the spindle speed and the feed rate has the smallest effect on the surface roughness. The suitable regression model of surface roughness is quadractic function. The predicted results of surface roughness are very close to the experimental values of that one. The genetic algorithm was used to find the optimal value of surface roughness. In this study, the optimum value of surface roughness was obtained for each case of drill tool diameter. The optimized cutting parameters was applied to improve the surface roughness with very satisfactory results. The optimum value of surface was quite small.

Experimental Study on High Performance Concrete by using Partial Replacement of Copper Slag and Fly Ash

The conventional concrete has lost its usage nowadays as it does not set out the present need. The term ‘High Performance’ is because of the essential usage, materials and proportions of this concrete are specifically chosen for properties such as high workability, high density and low permeability. The main objective of this study is to deal with the effects of cementitious materials in High Performance Concrete HPC for mix design of M40 grade concrete. Hence, copper slag which is the industrial by product is used as a partial replacement of fine aggregate by 0 , 15 , 30 , 45 , 60 and 75 with 20 of fly ash by the volume of cement with water cement ratio 0.36. Super plasticizer conplast SP430 is used as chemical admixture at the rate of 1.2 of cement which improves the workability. From this experimental study, so far the utilization of copper slag and fly ash observed with gradual improvement in mechanical properties such as compressive, split tensile and flexural strength in HPC. By evaluating the optimum percentage of copper slag,

Behaviour of Glass Fiber Reinforced Polymer Composite in Flexure Shear Strength of Reinforced Concrete Beams

The corrosion of steel reinforcement in concrete reduces the life of structures, causes high repair costs and can endanger the structural integrity of the structure itself. Glass fibre reinforced polymer GFRP offers a number of advantages over steel especially when used in marine and other salt laden environments. GFRP reinforcing bars are gradually finding wider acceptance as a replacement for conventional steel reinforcement as it offers a number of advantages. Technical studies on a number of concrete structures, from five to eight years old and constructed with GFRP reinforcement, have shown that there is no degradation of the GFRP from the alkaline environment. Concrete is very strong in compression but it is extremely weak in tension. To resist the tensile stress, steel reinforcement is provided in concrete. Reinforcement corrosion and structural deterioration in reinforced concrete structures are common, and prompted many researchers to seek alternative materials and rehabilitation techniques. One such material that has been offered as an alternative to mild steel reinforcement is Glass Fibre Reinforced Polymer GFRP bars and flats. For the repair and strengthening of structural concrete members, strengthening with Glass Fibre Reinforced Polymer GFRP plates is an excellent option. The present work is to study the behavior of Shear resistance of the silica coated GFRP stirrups in the shear test zone. A series of studies were conducted using silica coated GFRP stirrups in shear zone. It is observed that beams with silica coated GFRP flats shear reinforcement have shown failure at higher loads than the theoretical failure loads. Further it is observed that GFRP flats as shear reinforcement exhibit fairly good ductility.

Overview of Cyborg Technology

In this research paper we will focus on the cyborg technology in cybernetic. Cyborg in cybernetic is a part of Artificial Intelligence AI . Artificial Intelligence is area of computer science that deals with the creation of intelligent machines or software that work and react like a human being. Cybernetic is the basic science of control system and communication in both areas that cover machines as well as living things. This paper will mainly be focusing on how Cybernetics and Artificial Intelligence work together. This paper will also include evaluation of cyborg technology in real world, benefits, drawbacks of cyborg technology and how cyborgs are different from robots.

An Experimental Investigation on Concrete with Copper Slag using Corrosion Resistance Techniques

Now a days, the application of waste material usage in building materials has increased effectively. Copper slag is a by product created during the copper smelting and refining process. This material represents a popular alternative to sand. Natural sand is used from river bed for all construction stage. Decreasing natural resources create the environmental issues and hence restriction on sand resulted in scarcity and increased in its cost. After long investigation industries and investigator all over the world to explore the possible utilization of copper slag. This paper mainly shows the corrosion in concrete by using copper slag and preventive measures from corrosion. In this project M30 grade of concrete is used. Two different types of corrosion inhibitors were used calcium nitrate and concare . The influence of copper slag on concrete was investigated with respect to the properties of concrete in the fresh state workability and hardened state mechanical properties and durability . Strength properties of concrete increased 40 replacement of fine aggregate by using copper slag. However further addition of copper slag caused reduction in strength. From chemical composition of copper slag Fe2O3 present in more than 55 . So that here concrete itself getting corrode. Here corrosion inhibitors at the amount of 1 , 2 and 3 by the weight of cement in concrete having copper slag as a fine aggregate is used. Effect of this inhibitor was derived from gravimetric method.
