Abstract:This paper aims at the reduction of casting defects of a plate cylinder which is used in an offset printing machine to transfer ink from the inking unit. Four variables are considered which directly affect the casting of the cylinder. Taguchi method was selected for the optimization of these selected four parameters. Taguchi method is based on performing evaluation or experiments to test the sensitivity of a set of response variables to a set of control parameters (or independent variables) by considering experiments in "orthogonal array" with an aim to attain the optimum setting of the control parameters. Four control parameters were used to reduce the defects that occur on the plate cylinder.Moisture Content, green strength, sand particle size and mould hardness were selected as the control parameters. The analysis showed a reduction in the number of defects when optimum input factor values were selected. Keywords: Green strength, mould, orthogonal, taguchi

Abstract:This paper presents a design method and a vibration analysis of a carbon/epoxy composite drive shaft. The design of the composite drive shaft is divided into two Gears are one of the most critical components of mechanical systems, automobiles and rotating machineries. They vary from tiny size used in watches to very large size used in marine speed reducers, bridge lifting mechanism and railroad turn table drivers. Because of their high degree of reliability, efficiency and compactness gears are widely used as the power transmitting components in most of the mechanical system. Prototype testing a site reports suggest that gear contact ratio has significant effect on the generated noise level, especially in spur gear applications. High contact ratio (HCR) terminology is attributed

Abstract: The whole-body vibration (WBV) experienced by automobile drivers and the effects of WBV have been widely investigated. There exists a need to review the research literature investigating the evidence of WBV in automobile drivers and the effects of WBV. The aim of this review is to determine whether WBV exists in automobile drivers and then to find out the effects of WBV. Low Back Pain (LBP) is the most common musculoskeletal disorder (WMSD) resulting from WBV. Studies have shown that there exists a relationship between WBV exposure

Abstract:Fiber reinforced composite material was prepared by reinforcing nanoclay modified isophthalic polyester resin with glass fiber mat. Polyester resin was modified with nanoclay cloisite15A. The Dynamical Mechanical behaviorwas studied for pure polyester modified with 0.5%, 1%, 1.5% and 2% nanoclay and reinforced with 5 layers of glass fiber mat. The tests were done at temperature levels from room temperature to 150 oC. The storage modulus decreases with temperature and improved performance noticed for the 1% nanoclay filled sample. The creep

Abstract: Light weight materials coupled to the need for cost-effective processing have combined to create a significant opportunity for aluminium powder metallurgy as its increasing interest. Aluminium alloy (AA 2219) metal matrix composite reinforced with multi walled carbon nanotube (MWCNT) produced by powder metallurgy (P/M) technique was analysed and CNTs dispersion were traced. The micro hardness and the electrical resistivity of the composites were measured from room temperature. The reasons for decrease in electrical resistivity at room temperature with increasing volume fraction of the carbon nanotubes were investigated These composites are being projected for use in structural applications for their high specific strength as well as functional materials

Abstract: Lightweight ballistic body armor made of laminated composites exhibits superior ballistic performance compared to metallic materials and could replace high density metallic materials of body armor giving sufficient energy saving and mobility for the wearer. But, damage of composites body armor when subjected to ballistic impact causes sufficient strength reduction mainly due to matrix cracking, delamination and fiber breakage and thus

Abstract: Printing press is one of the main products of HMT Ltd, Kalmassery. A printing press is a mechanical device for applying pressure to an inked surface resting upon a medium (such as paper or cloth), thereby transferring an image. The main component of this machine is the press cylinders. These cylinders are manufactured in the casting section in HMT. Nowadays they are producing according to the order received. The production is less in number compared to earlier period. Nowadays the defects during the casting of press cylinder are high in such a way that if 10 cylinders are casted 5 of them are rejected. Because of

Abstract: Making technologies are currently formed as on basics of adaptability, self-ruled producing and level of automation. As the modernisation starts in making process, it is needed to update technologies in order to keep in competition. In such way that without any doubt cheaper products, shorter making time is needed .With the increase of machining parameters optimization is essential for production. In this paper an attempt is made to make a literature on optimizing machining parameters in turning processes by Taguchi method in MINITAB 17.0 software . Most

Abstract:Sandwich Plate System (SPS) is an alternative to conventional stiffened plate construction. Sandwich plate system is a lightweight material that consists of two metal plates separated by a core. Plates, usually made of steel, are joined via perimeter bars on the edges of the plate. Polyurethane elastomer core transfers shear and bending forces between plates and dissipates strain energy over a large area, reducing load concentrations and the possibility for permanent deformations. Sandwich plate system eliminates the need for secondary stiffeners, making the structure less complex and flush. Considering the high strength to weight ratio, ease of construction, blast and ballistic properties of the material, availability of a flush surface etc., SPS has been widely used in building bridges, stadiums, floors, blast walls etc. SPS panels have also been used in ship repair as an overlay on existing structures, converting
