Abstract

The average person spends hours a week driving, therefore it is important to make the car most ergonomic as possible in the most cost effective way. One area for improvement is the suspension. This research focuses on designing and fabricating a smart suspension for an electric car. To incorporate the idea of “smart” in the suspension, magnetism is incorporated into a normal damper with the concepts of eddy currents in mind. Eddy currents are produced when a nonmagnetic, conductive material is moved in a time-varying magnetic field. These circulating Eddy currents causes a repulsive force between the magnet and the conductor. The eddy current damping concept can be thus used as a form of viscous damping. Those magnetic fields create a drag force that can be used as a damper that behaves similarly to the oil dampers in vehicles today. With the use of oil and a magnetic damper together in the suspension system, the damping ratio in the suspension can be improved, thus improving the ergonomic properties of the ride. With the incorporation of the smart suspension in any car, it is possible to enhance the damping ratio to allow the car to perform smarter and smoother. The outcome of the research is an improved yet cost effective suspension system that can be mass produced. Most importantly, the eddy current based suspension system is simple and the damping does not require fluid or energy.
