“…Resonance frequencies are the most critical working points not only from the standpoint of comfort and safety, but also for the design of the actuator power and force values. These frequencies, given by expressions (7) and 8, are the natural frequency values of the two suspension subsystems: the 'suspension spring stiffness/sprung mass' and the 'tire stiffness/unsprung mass' [20].…”

Significant improvements in automobile suspension performance are achieved by active systems. However, current active suspension systems are too expensive and complex. Developments occurred in power electronics, permanent magnet materials and microelectronic systems justifies analysis of the possibility of implementing electromagnetic actuators in order to improve the performance of automobile suspension systems without excessively increasing complexity and cost. In this paper, the layouts of hydraulic and electromagnetic active suspensions are compared. The actuator requirements are calculated, and some experimental results proving that electromagnetic suspension could become a reality in the future are shown.

“…The mechanical structure of electromagnetic system is significantly simplified by replacing the hydraulic valves with electrical actuators [7][8][9][10]. Furthermore, it is benefited by the distinct properties of electrical actuators including extremely fast response and high energy efficiency [11][12][13]. Among the developed linear electrical actuators, linear permanent magnet synchronous motor (LPMSM) is of the highest performance [14].…”

Linear switched reluctance actuator (LSRA) is of great potential using in kind of high-force linear applications such as automotive suspension system. In this study, an electrical controlled active suspension system is built. Bi-directional power amplifier is used to supply power to and absorb generated energy from linear actuator based on the movement requirement. The linear motions are accomplished by retracting and extending the LSRA. With regard to the established electromagnetic suspension system, a real-time control algorithm is developed. Sliding model technique with adaptive mechanism is studied to compensate the system non-linearities and external road profile. Experiments are conducted at the laboratory to present the high performance of proposed active suspension system.

“…Early works on the development of advanced suspension system for military vehicles have been done using the electromagnetic suspension system (Maclaurin, 1983;Weeks et al, 1999), hydraulically actuated active suspension system (Wendel et al, 1994;Kanagawa et al, 1995Kanagawa et al, , 1996Hoogterp et al, 1996;Beno et al, 1997) and semi-active suspension system (Miller and Nobbles, 1988). Although most of the early works have investigated the dynamics performance of military vehicles on a simple vehicle model such as the one with single and two Degrees of Freedom (DOF), the advanced suspension systems are found to be able to increase the suspension performance of military vehicles.…”

This paper introduces the mathematical model of 12 Degrees of Freedom (DOF) light armoured vehicle, which consists of eight DOF in vertical motion of eight tyres, three DOF in vertical, roll and pitch motions of vehicle body and one DOF in angular motion of gun turret relative to weapon platform. Two sources of disturbance considered in this study are road irregularities and reaction force at the weapon platform. The results of the study show that the stability augmentation based active suspension system is able to significantly improve the dynamic performance of the light armoured vehicle compared with the passive system.
