Electromagnetic shock absorber

This paper introduces a novel passive suspension system for ground vehicles. The system is based a flexible electromagnetic shock absorber (EMSA). In the proposed system, it is attempted: (a) to select a variable high damping coefficient usable in a car; (b) physical dimensions and the geometry of EMSA not to be very different from mechanical shock absorbers; and (c) its weight and volume to be low for the core not to be saturated. After designing and providing a model, the results of the test model are compared with the behavior of a tubular linear induction motor, which is connected to DC supply. This system will have low cost and will be controllable.
