A Flexible Electromagnetic Damper

This paper introduces a new passive suspension system for vehicles. The system is based on a flexible electromagnetic damper. In the proposed system, it is attempted: a) to select a variable damping coefficient usable in a car; b) determine the physical dimensions and geometry of an electromagnetic damper to be not very different from mechanical dampers; and c) the weight and volume of the damper to be low and for the core not to be saturated. After designing and providing a model, the results of a test model are compared with the behavior of a tubular linear induction motor, connected to variable D.C. supply. This system will have low cost and be controllable.
