Joining of Dual Phase Coated Steel Sheets DP600

Currently, high strength steels are increasingly used in the production of car bodies. Car manufacturers choose steel with good formability, fatigue resistance, and the ability to absorb impact energy. DP dual phase steels verify the specific criteria mentioned above. Resistance spot welding is one of the most common methods of joining high strength dual phase steels. The paper focuses on the comparison of the properties of joints made by resistance spot welding. Selected properties were investigated by tensile test and metallographic observations. HCT600X Z and HCT600X ZF steel sheets were used for the experiments.

Mechanical Behaviour of AA 6061-Ca2SiO3 Composite

The advantage of composite materials over non alloy virgin metals has been on the front burner in the engineering materials sphere. To this ends, various reinforcement materials are constantly been mixed with metal matrix to form new composite materials. Ca2SiO3 is a ceramic material which finds application in medicine, heat and noise insulation, acid remediation, cement production etc. since it possesses qualities needed for the formation of composites, and is largely not researched on, this study aimed to characterize the mechanical properties of the AA 6061 Ca2SiO3 composite for different composition of percentage mix, and to establish a model that would predict the UTS for known values of percentage mix and load. Result of the study shows that 6 Ca2SiO3 - 94 AA 6061 and 24 Ca2SiO3 - 76 AA 6061 possessed the highest modulus of elasticity and are stiffer while 2 Ca2SiO3 - 98 AA 6061 mix had the lowest modulus of elasticity, and is more ductile than other composition mix. Also, it was observed that addition of Ca2SiO3 to AA 6061 T4 greatly improves its mechanical properties and96.43 of the variations in stress experienced by various percentage composition of the composite mix can be explained by the developed model.

CFD Analysis to Analyze Thermal Characteristics of a Heat Exchanger Handling Combination of Dimple Ribs

It takes a lot of energy to have a good life. For living and working, humans nowadays rely on an abundant and constant source of power. Because energy is depleting at such a rapid rate, it has become important to use heat more efficiently, which necessitates that we preserve. As a result of the global energy crisis, many researchers have worked to improve the efficiency of thermal systems and reduce the size and thus energy consumption rates, which is one of the most critical problems due to the large and continuing increase in consumption, the increasing scarcity of energy resources, and the high cost. A 3 dimensional numerical 3 D simulation was used to evaluate the thermal properties of a heat exchanger managing a combination of dimple ribs. Handling air flow velocity through the channel was varied from 3.97 to 5.80 m s. is the subject of this study. The heat transfer physiognomies of a heat exchanger managing a combination of dimple ribs were studied using the simulation tool ANSYS 19.2. The numerical results showed that the combination of dimple ribs enhanced heat transfer significantly more than the dimple. In comparison, the average Nusselt number of a combination of dimple ribs is 4.28 percent higher than that of a channel with dimpled Plate.

Development of Semi Automatic Operated Pneumatic Based Wire Stripping Machine

In recent years, the trend in the business has been toward more automation. A growing number of variables, including improving accuracy and reducing human error, are driving this trend. An in depth examination of the design and development of a pneumatically driven cable stripping machine for industrial mass production is provided in this dissertation, which includes an extensive bibliography. To cut the cable in large diameters in mass production, the industry now employs the traditional technique of employing a cable cutter, which takes longer and needs more manpower to cut the cable than other methods. The precision achieved by the traditional technique is low, and the procedure is time consuming. In addition to providing a solution to the traditional way of solving issues, automation reduces costs and saves time while also increasing accuracy and reducing human mistakes. By using automation, we want to achieve low cost stripping that is both quick and efficient, thereby reducing stripping time. The practical goal of an automated cable stripping machine is to remove the PVC from a cable at the necessary length and in the required number of pieces, according to the specifications. The stripping process in this system is accomplished via the use of pneumatic pressure and an Arduino. In our project, a solenoid valve is utilized to activate a pneumatic double acting cylinder, which is controlled by an Arduino.

Harvesting Renewable Energy by Using Human Foot Step

Man has used tremendous amount of energy for his daily needs. Due to this a lot of energy resources have been exhausted and wasted. Proposal for the utilization of waste energy of foot power with human locomotion is very much relevant and important for highly populated countries like India where the railway station, temples etc., are overcrowded all round the clock. In this paper the force energy is produced by human footsteps and the force energy is converted into mechanical energy by rack and pinion mechanism, electricity is produced by dc generator. And this power source has many applications as in agriculture, home application and street lighting and as energy source for sensors in remote locations. This thesis is all about generating electricity when people walk on the Floor. Think about the forces you exert which is wasted when a person walks by. The idea is to convert the weight energy to electrical energy The Power generating floor intends to translate the kinetic energy to the electrical power. Energy Crisis is the main issue of world these days. The motto of this research work is to face this crisis somehow. Though it won’t meet the requirement of electricity but as a matter of fact if we are able to design a power generating floor that can produce 100W on just 12 steps, then for 120 steps we can produce 1000 Watt and if we install such type of 100 floors with this system then it can produce 1MegaWatt. Which itself is an achievement to make it significant.

CFD Analysis of a W Ribbed Roughness Solar Air Heater

Solar air heaters are used to heat up air which can be used for various purposes. Computational Fluid Dynamics CFD has proved to be a boon for researchers to estimate performance of any machine at design stage only. In the present work, a 3 dimensional CFD investigation has been completed of sun powered air radiator to ponder heat exchange and liquid stream conduct in a rectangular pipe of a sun oriented air warmer with one roughened divider having blend of round and square transverse wire rib harshness. The impact of Reynolds number, harshness tallness, unpleasantness pitch, relative unpleasantness pitch and relative harshness stature on the warmth exchange coefficient and rubbing factor have been considered. From the investigation it has been found that, W formed harshness gives better warmth exchange rate as contrast with the V rib unpleasantness under comparable working conditions. The most extreme estimation of Nusselt number for W formed harshness is acquired with the relative unpleasantness pitch P e of 10 past that it begins diminishing.

Numerical Evaluation of Temperature Distribution and Stresses Developed in Resistance Spot Welding

Resistance spot welding is a type of electric resistance welding used to weld various sheet metal products through a process in which contacting metal surface points are joined by the heat obtained from resistance to electric current. The intense heat generated and rapid cooling of the joint produce residual stresses and distortion in the joint. The prediction of residual stresses before carrying actual welding is important for the prevention of these stresses. In this study thermo elasto plastic analyses are carried out to simulate resistance welding under various conditions. Mild steel sheets of equal and unequal thicknesses and aluminium sheets of equal and unequal thicknesses have been spot welded with the application of pressure which is determined by measuring force on the joint with a load cell. The size and shape of the nugget for different spot welding conditions is ascertained. The residual stresses under different spot welding conditions are compared.
