Abstract: The main objective of this project is to design and develop a 2-Stage- Reduction gearbox for all terrain vehicles application. Gearbox is a mechanical unit consisting of series of gears within a housing (casing) or a simple gear train. It is the main component of the powertrain system as it provides speed and torque conversions from the Engine or CVT to the wheels. The gears inside of gearbox can be any one of a number of different types of the gear that are available in the market i.e., from spur gears to worm gears and planetary gears as well. In this report the gearbox is made from a helical gear train. This report focuses on selection of overall reduction ratio of the gearbox, material selection, selection of gear dimensions, selection of shaft dimension, design of key and bearing selection from SKF bearing catalogue. The bending and wear strengths are calculated to determine factor of safety and later, Finite element analysis is performed to validate the results.

AbstractIn recent years, the use of single-tube skeletons for the construction of Chinese solar greenhouses has increased. As a consequence, during the selection of the construction materials, the safety of these structures has become an important issue. The single tube section has various forms, but there is no scientific theory to guide the selection process. To the best of our knowledge, the scientific analysis of the impact of single pipe cross section on the safety of greenhouse skeleton has not been addressed so far. In this context, the finite element analysis software was used to calculate and analyze the stress elements, displacement of round tube, Ω tube, elliptic tube and square tube under the same load conditions. We used the Chinese Standard values as a reference and analyzed structural features of different sizes and thicknesses of the greenhouse steel skeleton sections under non-uniform snow load. The results showed that, under the same load condition, the maximum stress in the four skeleton materials was all located at the connection of the transverse tension bar and the front roof. In addition, under same load condition, the greenhouse skeleton with elliptic tube presented the smallest cross-sectional displacement between the different materials tested. The effect of increasing the size of the greenhouse frame was better than that of increasing the greenhouse material thickness. All this work will provide theoretical guidance to the material selection of this structure.

Connecting rod is one of the most important components of an internal combustion engine and transfers motion from the piston to the crankshaft and function as a lever arm. Existing connecting rod is manufactured by using C-70 alloy steel. In the current study, connecting rod is replaced by E-glass/Epoxy composite material for universal tractor. The static strength of connecting rod is analyzed in detail and the maximum stress is found. Some improvement methods are also provided for the material selection of connecting rod. Connecting rod is modeled in CATIA V5 software and it is imported in ANSYS 14 workbench for analysis. The main objective of this study is to perform the static analysis of universal tractor connecting rod to find out its static strength using ANSYS 14 workbench. Finite element analysis is done by considering composite materials. The best combination of parameters like Von mises stress, deformation and weight reduction for connecting rod is carried out.

In any automobile the power is transmitted from one shaft to another by using chain drive. Chain drive consists of chain, driving sprocket and driven sprocket. The driving sprocket is connected to engine output shaft, which transfer power to driven sprocket by chain. Further this driven sprocket transfer power to drive shaft. The design and material selection of this chain drive plays a vital role in efficient running of the automobile. Present the material used for chain drive is mild steel. This paper involves increases the strength of the Pulsar 180cc chain drive by selecting the different materials (AISI 1050 steel, EN 8 steel, EN 32 steel, EN 19 steel and C45 steel). In this the Pulsar 180cc chain drive designed through reverse engineering approach and detailed finite element analysis is carried out to calculate stresses and deflections on the chain drive. Later the analysis is extended to fatigue analysis to estimate the life of the chain drive and the dynamic analysis is carried out to calculate stresses and deflections on the chain drive when it is in motion. SOLID WORKS software is used for doing 3D model of chain drive and ANSYS is used for doing finite element analysis.

Abstract Polyethylene (PE) pipes are widely used in oil and gas transportation, municipal construction. Electrofusion (EF) welding is one of the most commonly used connection method for PE pipes. The welding quality of EF joints is crucial to the safety of PE pipeline. Resistor wire is an important part of pipe fittings, and has great influence in final welding quality and strength of EF joints. In this paper, we discussed the influence of resistor wire for EF fittings in the aspect of selection of resistor wire materials and determination of structural dimensions. Resistivity and temperature coefficient of resistance (TCR) are two factors for material selection. In addition, the influence of resistor wire structure, i.e., resistor wire spacing, resistor wire diameter, on the stress distribution of EF joint was discussed through finite element analysis. The results revealed that the maximum stress in EF joint increase with the diameter of resistor wire, and is barely affected by resistor wire spacing.

Selection of material is a crucial part of the voyage of obtaining the optimal product. The task is challenging for the designer who has to select the optimal material from a list of thousands of materials that satisfy the tangible and intangible criteria. The problem of identification of the optimum material can be solved using different MCDM (multi-criteria decision-making) tools. This chapter proposes to select the optimal material for polymeric composite bumper beam using TODIM (tomada de decisao interativa multicriterio, which means in Portuguese “interactive and multi-criteria decision-making”) method. Six different composite materials were considered. Glass fiber epoxy turns out to be the optimal material for the bumper beam. Further, finite element analysis was carried out to study the behavior of the candidate materials under specific loading conditions.

Flat Cover

A flat cover of an adjustable ballast tank made of high-strength maraging steel used in deep-sea submersibles collapsed during the loading process of external pressure in the high-pressure chamber. The pressure was high, which was the trigger of the collapse, but still considerably below the design limit of the adjustable ballast tank. The failure may have been caused by material properties that may be defective, the possible stress concentration resulting from design/processing, or inappropriate installation method. The present paper focuses on the visual inspections of the material inhomogeneity, ultimate cause of the collapse of the flat cover in pressure testing, and finite element analysis. Special attention is paid to the toughness characteristics of the material. The present study demonstrates the importance of material selection for engineering components based on the comprehensive properties of the materials.

Porous asphalt (PA) mixtures are more environmentally friendly but have lower durability than dense-graded mixtures. Additives can be incorporated into PA mixtures to enhance their mechanical strength; however, they may compromise the hydraulic characteristics, increase the total cost of pavement, and negatively affect the environment. In this paper, PA mixtures were produced with 5 different types of additives including 4 fibers and 1 filler. Their performances were compared with the reference mixtures containing virgin bitumen and polymer-modified bitumen. The performance of all mixes was assessed using: mechanical, hydraulic, economic, and environmental indicators. Then, the Delphi method was applied to compute the relative weights for the parameters in multi-criteria decision-making methods. Evaluation based on distance from average solution (EDAS), technique for order of the preference by similarity to ideal solution (TOPSIS), and weighted aggregated sum product assessment (WASPAS) were employed to rank the additives. According to the results obtained, aramid pulp displayed comparable and, for some parameters such as abrasion resistance, even better performance than polymer-modified bitumen, whereas cellulose fiber demonstrated the best performance regarding sustainability, due to economic and environmental benefits.
