Elektrizität wird erzeugt, indem die üblichen Drehzahlschalter durch einen einfachen Mechanismus ersetzt werden. Es ist sehr wichtig, ein umweltfreundliches Energieerzeugungssystem zu entwickeln. Speed breaker Power Generator (SBPG) ist die am weitesten entwickelte Technik, die mit minimalem Aufwand elektrische Energie erzeugt. Wenn Fahrzeuge über die Geschwindigkeitsbremsen fahren, arbeiten Zahnstangen und Ritzel und erzeugen mit Hilfe von Hochspannungsfedern Strom. Diese Methode ist ein effektiver Weg, um Strom zu erzeugen, da die Zahl der Fahrzeuge ständig zunimmt. Sie kann in der...

Compressed air as a source of energy in different uses in general and as a non-polluting fuel in compressed air vehicles has attracted scientists and engineers for centuries. Efforts are being made by many developers and manufacturers to master the compressed air vehicle technology in all respects for its earliest use by the mankind. The present research gives a brief introduction to the latest developments of a compressed -air vehicle along with an introduction to various problems associated with the technology and their solution. While developing of compressed air vehicle, control of...

Les composites en alliage d'aluminium présentent de meilleures caractéristiques mécaniques, ce qui leur permet de trouver des applications potentielles dans des composants industriels tels que les engrenages, les glissières, etc. Dans ce travail, un composite d'alliage AA7075-Cobalt/Nickel/Graphite a été fabriqué par la méthode du moulage par agitation. Les spécimens d'alliage ont été analysés pour leur évaluation physique, mécanique et l'usure par glissement. Les résultats prouvent que le renforcement améliore les performances physiques, mécaniques et d'usure par glissement...

Solar drying is one of the most ancient and simplest forms of drying known to mankind. Even today, most of the agricultural product such as grains, spices, fruits and vegetables are dried under the sun. However, drying these products directly under the open sun has many drawbacks such as debris, rain, blowing wind, insect interaction, human and animal interference etc. which leads to contamination of the products. Thus, there is a need to make the solar dryers more efficient and cheaper. There are various types of solar dryers developed and are classified based on the mode of air circulation,...

The design and fabrication of manually operated pesticide sprayer. Sprayer consists of back pack sprayer which is mounted on the tank base of the trolley. The piston rod of the tank is connected to the crank, which is mounted on the smaller gear, which in turn is meshed with a larger gear; the larger gear is mounted on the trolley. The pump is connected to the pressure tank, which pressurizes the fluid during operation and stores in the pressure tank. Using a flexible hose, the pressurized pesticide is transferred to the multiple nozzles. According to the need the valve is operated so as to...
