| Summary: | More papers are written about Active Anti-roll bars (AARB) in automotive and mechanical field. These systems are usually designed for vehicles to change the roll stiffness of the vehicle, thus preventing a potential roll-over. In this present paper, the use of AARB will be analysed from two different perspectives in ride and handling. First, this paper proposed the basic vehicle dynamic modeling with four DOF (degree of freedom) on half car model are described that show, why and how it is possible to control the handling and ride comfort of the car, with the external forces on the front anti-roll bar. Basically, this paper is focused on understanding the vehicle dynamic behaviour under the influence and the effects of anti-roll bar mechanism. Simulated tests are presented, that shows how the characteristics of the body roll angle and roll rate responses by using MATLAB/SIMULINK software. By simulation analysis, the design model is validity and the performance under control of PID controller is achieved. Finally, some basic conclusions are drawn about the applicability of the possible control strategies will be investigated for such system in the future. |
