Abstract

Knowing the fact that the suspension system is the only connecting point between the vehicle and the rarely uniform road, we strongly believe that the suspension system is the most significant part of extraordinary importance in providing comfort and driving safety against specific road conditions and situations. Therefore, the purpose of this research was to study the performance of three different suspension systems: passive, semi-active and active. To analyze the specific parameters and to compare the performance results of three types of suspension systems, the representative ¼ model of the vehicle, represented as a two degree of freedom system, is modeled and simulated in the MATLAB/Simulink environment. Differential motion equations describing the three systems are subjected to software modeling and simulation, providing information on the behavior of these systems for the same parameters, under the same conditions. The comparison of the numerical and graphical results between the three systems proved that the active suspension systems, controlled by a controller, offer significantly better performance than the previous systems in terms of response time (by tuning, in order to achieve proper rise time, overshoot, settling time and steady-state error) and adjustment of system suspension as well as reduction to dissipation of vertical oscillations, roll and pitch movements, which was also the aim of this research.
