Zero Friction Electromagnetic Braking System Project
ABSTRACT: MOST OF BRAKING SYSTEM RUN ON THE PRINCIPLE THAT RELEASE OF KINETIC ENERGY TO THE HEAT ENERGY. THIS IS THE METHOD WHICH HAS ITS OWN DISADVANTAGES AND MUST BE REPLACED WITH MORE EFFICIENT BRAKING SYSTEM THAT I RESPOND QUICKLY, DOESN’T HEAT AND ALSO MAINTENANCE FREE. IN THIS PROJECT, A FRICTIONLESS BRAKING SYSTEM IS PROPOSED USING EDDY CURRENT PHENOMENON. THIS PHENOMENON IS ADMINISTRATED BY FARADAY’S LAW OF ELECTROMAGNETIC INDUCTION AND LENZ’ LAW. EDDY CURRENT IS GENERATED BY THE RELATIVE MOTION BETWEEN A METAL, ALLOY CONDUCTOR AND A MAGNET. THE CURRENT INDUCES MAGNETIC FIELDS IN THE CONDUCTOR WHICH OPPOSES THE ACTUAL MAGNETIC FIELD OF THE MAGNET AND RESULTS IN THE DECELERATION OF MOTION (LENZ LAW). THE CONSTANT MAGNETIC FIELD IS THE EASIEST DESIGN TO IMPLEMENT. THE MECHANISM WHICH IMPLEMENTS THIS PHENOMENON IN EVOLVING BRAKING SYSTEM. THIS BRAKING SYSTEM IS FRICTIONLESS, HENCE IT’S ADVANTAGEOUS OVER CONVENTIONAL FRICTION BRAKES IN TERMS OF PERFORMANCE AND MAINTENANCE. THE PROPOSED SYSTEM IS IMPLEMENTED IN REAR WHEEL OF VEHICLES.
INTRODUCTION Magnetic brakes (also called eddy current brakes or EC brakes) slow or stop motion using magnetic force to apply mechanical resistance (friction). The original name was "eddy-current brakes" but as the years passed by, the name changed to "magnetic brakes", referring to their method of actuation. Having becoming famous in the middle of the 20th century especially in trains and trams, the variety of applications and brake designs has increased significantly, but the basic operation remained the same. Magnetic brakes are the brakes working on magnetic power. They work on the principle of magnetism. These brakes are a great replacement on the regular brakes due to their many merits. The reason for using this brake in vehicles is to reduce damage in brakes as it frictionless. Magnetic brakes are of possible use today’s vehicles. The working principle of this system is that when the magnetic field passes through and at right angles to the rotating disc an eddy current is produced opposite to the rotating disc direction. This eddy current tries to stop the rotating disc. This results in the rotating disc comes to a halt.
1.2Types of Braking Systems Electromagnetic Brake System A growing style of brakes, electro magnetic brakes use a motor that is comprised in the automobile which assist the automobile come to rest. These types of the brakes are used in maximum hybrid vehicles and use a motor to charge the battery and regenerative brake. instance, some buses will use it as a subordinate retarder brake. Frictional Brake System A frictional brake is found in numerous vehicles. They are provisional brakes, and naturally found in two types; pads and shoes. As the name suggests, these brakes use friction to brake the vehicle from moving. They typically comprise a rotating disc with a stationary pad and a rotating surface. On most band brakes the shoe will compress and rub against the external of the rotating drum, otherwise on a drum brake, a rotating drum with shoes will enlarge and rub against the interior of the drum. Hydraulic Brake System A hydraulic brake system is containing a master cylinder that is supplied by a reservoir tank of hydraulic braking fluid. This is linked by a collection of rubber fittings and metal pipes which are connected to cylinders of the wheel. The wheel contains two opposite piston which are located on the band, drum brake which are pressured to push the pistons distinctly forcing the brake pads in the cylinders, thus triggering the wheel to retard motion.
Here we shows the demonstration of “ The Frictionless Braking System Mechanical Project”, where, it shows the Copper’s surprising reaction to Strong Magnets. A friction-less braking system tends to increase life span and reliability of brakes since absence of friction leads to less wearing of brakes. Under operation it requires less maintenance and oiling as compared to other braking mechanisms. Our mechanism makes use of a well designed and fabricated assembly to demonstrate the concept. We make use of a copper brake drum with a chain sprocket based arrangement which is driven by a motor. The arrangement is fixed on a shaft arrangement rotating seamlessly on a bearing mounted arrangement to simulate a car wheel. The system is now integrated with a strong magnet arrangement. This double sided magnetic arrangement is used to simulate a brake paddle push. Once pushed it traps the brake drum in strong magnetic field and braking takes place.
