Magnetic Suspension for Motorcycles

Suspension is a mechanical arrangement contributing to vehicle's road handling behavior. If roads were perfectly flat with no irregularities, suspensions wouldn't be necessary. It's these imperfections that apply force to the wheels. There are many types of suspensions such as double wishbone, trailing arm and air shocks. But these suspensions possess some disadvantages such as vibration, mechanical failure and stiffness variation. So in this paper we have introduced the idea of ?MAGNETIC SUSPENSION? which will enhance the driving pleasure and control over road. Magnetic suspension will allow us to get variable stiffness and much higher comfort just by playing with magnetic field. It will also allow us to reduce wear and tear along with less maintenance. The magnetic suspension has two cylindrical tubular structure having electromagnets on both ends. The magnetic field will be induced using battery power which is produced by electromagnets using a feedback loop. Also when current passes through a wire, a magnetic field around that wire is generated. When the current through the wire stops, so does the previously generated magnetic field. The strength of the generated magnetic field is proportional to the rate of current through the wire. When a wire is coiled, this generated magnetic field is concentrated to the centre of the coil. The strength of this field can be increased by placing a ferromagnetic material in the centre of the coil. The arrangement will be in such a way that same poles will be facing each other resulting in repulsion of the magnets. That is either (+) positive - (+) positive or vice versa. Reducing vehicle's vibrations while travelling on irregular roads, the magnets will act as dampers and damping effect will be produced due to repulsion between them. Moreover stiffness can also be controlled by varying magnetic field according to the requirement.
