Abstracts: Magnetic suspensions works where two or more magnets of the same polarity absorb all the bumps. The main problem is making the magnets strong enough when running off cars. The design and analysis of a scale-model suspension test facility for BICYCLE MAGNETIC SUSPENSION is discussed. This work describes techniques for the design, construction and testing of the prototype magnetic suspension system. The viability of future high-temperature super conducting magnet design for BICYCLE MAGNETIC SUSPENSION has been investigated with regard to their application to active secondary suspensions. In this project of magnet suspension after the suspension has been fabricated the suspension would be test for various tests to check it performance. The test would be conducted for different load, speed and road condition. For the same we would require various equipments like dial gauges, speedometer, etc. This purpose of this magnetic suspension is to improve the damping effect of the shock. A survey of present proposals for magnetic levitation is presented, in addition to a brief discussion of various factors involved in the development of such a mode of suspension. While the variety of possible systems is considerable, only a few of these have been adequately researched. In the United States, emphasis has been placed upon systems obtaining levitation heights of several inches, derived from the repulsion arising between a moving superconducting coil and a metallic track in which currents are induced. In England, efforts have been concentrated on suspension utilizing the repulsion of permanent magnets; while clearances are small (roughly 1 cm.), drag losses inherent in the American schemes are absent, and levitation exists without the necessity for the forward motion of the vehicle. The development of magnetic suspension has not advanced far beyond the stage of theory, fundamental experiment, and demonstration of models. For this reason, it is expected that magnetic suspension, while having several advantages over conventional modes of suspension, will not be available before the 1980's. This MSBS is manufactured by Mitsubishi Heavy Industries.(MHI) on the basis of the collaborative investigation with National Aerospace Laboratory in Japan (NAL). NAL has continued their research independently since NAL succeeded in magnetic suspension in 1987 for the first time in Japan. Then, MHI has recently added some original improvements to this MSBS. MSBS provides an ideal way of supporting a model for wind tunnel tests because the forces and moments to support the model are generated by magnetic field controlled by the coils arranged outside the test section. There is no support interference problem because any mechanical support system is not needed in the flow field. MSBS will expand new wind tunnel testing because of examining various kind of three-dimensional body without any mechanical support system in wind tunnel.
