Abstract

Previous research has shown that passive electromagnetic damping could be feasible for automotive applications, but there would be a severe weight penalty, particularly in light weight vehicles. With modern advances in permanent magnets the feasibility of passive electromagnetic dampers is re-examined. A model of a permanent magnet and coil system is developed and validated in small scale. This magnet model is used to model a dynamic damper system which is again tested. Finally this dynamic model is then scaled up to a two degree of freedom system to determine the damping for a quarter car model. Two damper designs are created. While both dampers could achieve practical real-world damping levels, but both are at least a factor heavier than a comparable commercial hydraulic damper. Keywords: Electromagnetic, magnetic, EM, damping.
