Abstract
This paper presents the model of the electromagnetic active suspension consisting of an electromagnetic actuator and a mechanical spring. Furthermore, the authors investigate the effects of two crucial parameters, which are the spring stiffness and actuator force, on performances of the suspension. The study shows that the large spring stiffness results in the small initial displacement and requires the large actuator force, the small spring stiffness leads to the large initial displacement and needs the small force, and the large actuator force improves steady-state and dynamic performances and results in large volume, more weight and high cost of the actuator. Thus, this paper is considerable valuable for better designs of the electromagnetic active suspension and the actuator.
