A review on influence of different flushing methods on Material Removal Rate using EDM.

2019-11-21
2019-28-2543
Electrical release machining (EDM), is a material removal procedure whereby a coveted shape is acquired by utilizing electrical releases (sparks). Material is expelled from the work piece by a progression of quickly repeating current releases between cathode and anode, isolated by a dielectric fluid and subject to an electric voltage. At the point when the voltage between the two terminals is expanded, the power of the electric field in the volume between the anodes winds up more prominent than the quality of the dielectric (in any event in a few spots), which separates, enabling current to stream between the two cathodes. This wonder is the equivalent as the breakdown of a capacitor (condenser). Accordingly, material is expelled from the cathodes.

A Mathematical Approach to Determine Die Wear during Forging Process and Validation by Experimental Technique

2019-11-21
2019-28-2563
The automotive industry is constantly trying to develop cost effective, high strength and lightweight components to meet the emission and safety norms while remaining competitive in the market. Forging process plays an important role to produce most of the structural components in a vehicle. Precision forging technology is used to produce components with little or no flash leading to elimination of machining process after forging. The load acting on the dies during net or near net forging is very high and leads to wear in the die. In order to have a good die it is important that die wear which is an inevitable phenomenon in a bulk metal forming processes is predicted mathematically. In this study a review on the vast number of studies done in the area of wear and various predictive models is carried out.

A Technical Review on Performance and Emissions of Compressed Natural Gas – Diesel Dual Fuel Engine

2019-11-21
2019-28-2390
In view of the depletion of energy and environmental pollution, dual fuel technology has caught the attention of researchers as a viable technology keeping in mind the increased availability of fuels like Compressed Natural Gas (CNG). It is an ecologically friendly technology due to lower PM and smoke emissions and retains the efficiency of diesel combustion. Generally, dual fuel technology has been prevalent for large engines like marine, locomotive and stationary engines. However, its use for automotive engines has been limited in the past due to constraints of the limited supply of alternative fuels. CNG is a practical fuel under dual-fuel mode operation, with varying degree of success. The induction method prevents a premixed natural gas-air mixture, minimizes the volumetric efficiency and results in a loss of power at higher speeds.

Methodology for failure simulation Using 4 corner 6 DOF Road load simulator of Overhanging Components: An Experimental Approach

2019-11-21
2019-28-2404
Nowadays, Road Load Simulators are used by automobile companies to reproduce the accurate and multi axial stresses in test parts to simulate the real loading conditions. The road conditions are simulated in lab by measuring the customer usage data by sensors like Wheel Force transducers, accelerometers, displacement sensors and strain gauges on the vehicle body and suspension parts. The acquired data is simulated in lab condition by generating ‘drive file’ using the response of the above mentioned sensors. For generation of proper drive file, not only good FRF but ensuring stability of inverse FRF is also essential. Stability of the inverse FRF depends upon the simulation channels used. In this paper, an experimental approach was applied for focused failure simulation of engine mount, one of such low correlation zone, with known history of failure.

2019-10-11
2019-28-0175
Friction Stir Welding (FSW) is a quite new solid-state joining process. This joining technique is energy efficient, environment friendly, and adaptable. In particular, it can be used to join high-strength Aluminium alloys and other metallic alloys that are difficult to weld by conventional fusion welding. Friction Stir Welding heats metal to the temperature below re crystallization. FSW avoids welding defects like porosity and hot cracking which are frequently in conventional welding techniques due to alloy’s very low re-crystallization temperature and higher heat dissipating nature. This process combining deformation heating and mechanical work to obtain high defect free joints. Aluminum alloy 7075-T6 is generally used in various industrial applications such as automobile, ship building and aerospace due to their light weight, good mechanical properties and high corrosion resistance.

Amelioration of modular mobility by adopting split cell solar panel cleaning and cooling therof

2019-10-11
2019-28-0078
In photovoltaic system the efficiency of solar cells is determined in combination with latitude and climate. The electricity generation in photovoltaic cell is more in the morning time than in the afternoon time. This is due to the fact that an increase in solar cell temperature leads to a decrease in efficiency of the solar panel. This work aims to provide necessary cooling to the solar panel for favourable output during noon time. Normally electrical modular vehicles use non-split cell solar panels. In order to increase the efficiency, we are using split cell solar panel as it increases voltage by halving the size of the silicon chips. Thus, halving the cells results in increasing efficiency and lowering the operation temperature. The solar panel should be maintained at a particular temperature by adopting sprinkling of water method in solar panel for hybrid vehicles.

Aerodynamic Drag Reduction of a Intercity Bus through surface modifications- A Numerical Simulation

2019-10-11
2019-28-0045
The maximum power produced by the Engine is utilized in overcoming the Aerodynamic resistance while the remaining has been used to overcome rolling and climbing resistance. Increasing emission and performance demands paves way for advanced technologies to improve fuel efficiency. One such way of increasing the fuel efficiency is to reduce the aerodynamic drag of the vehicle. Buses emerged as the common choice of transport for people in India. By improving the aerodynamic drag of the Buses the diesel consumption of a vehicle can be reduced by nearly about 10% without any upgradation of the existing engine. Though 60 to 70 % of pressure loads act on the frontal surface area of the buses, the most common techniques of reducing the drag in buses includes streamlining of the surfaces, minimizing underbody losses, reduced frontal area, pressure difference between the front & rear area and minimizing of flow separation & wake regions.
