Electromagnetic Damping in Shock Absorbers

Abstract

In the shock absorber, springs are used as dampers which hold the weight of vehicle, rider(s), and cargo. After certain interval of time, the stiffness of the spring gets reduced due to some parameters e.g. load, oscillation, etc.; because of that, there will be imbalance in the vehicle, which would lead to loss of control and hence major accident. In order to prevent such untorn events, I will present some measures in this paper that will roll off these drawbacks. Instead of using spring, damping is provided with magnetic repulsion between the edges of solenoid and magnet, where the magnetic flux from electromagnet can be controlled by varying the current passing through electromagnet, using concept of electromagnetic induction. That will give the linear relationship between stiffness (repulsion) and flux. The above-mentioned measures are easy to implement and enhance the vehicle balance.
