The Design and Modeling of an Active Suspension System with Linear Stepping Motor

In this study, using of the hybrid linear stepping motor structure which is currently being used for different systems in the active suspension system is investigated theoretically. The linear stepper motor for the suspension system is designed and modeled. Current and magnet thrust force characteristics were determined and this relation was transferred to MATLAB / Simulink model which is prepared for quarter model as a gain element. The behavior of the system has been examined comparatively for passive and active suspension systems by obtaining time and frequency responses. From results, it has been observed that the active suspension vehicle system showed better vibration damping performance than the passive suspension system
