This paper explores the potential of semi-active anti-roll bars utilizing magnetorheological (MR) technology. It begins with a detailed discussion of MR technology's principles, followed by an examination of its integration into semi-active anti-roll bar systems. The experimental setup includes dynamic driving tests comparing the performance of semi-active anti-roll bars against passive and fully active systems. MR technology enables rapid adaptation of the anti-roll bar's stiffness and damping properties to match driving conditions, thereby enhancing vehicle stability and ride comfort during dynamic maneuvers. Performance evaluation is based on vehicle dynamics tests conducted on a proving ground, assessing the semi-active system's influence on vehicle handling characteristics such as roll angle and understeer behavior. Results demonstrate that the semi-active system, despite its simplicity and lower power requirements compared to fully active systems, provides significant improvements in handling dynamics. These benefits are achieved without the complexities and higher costs associated with fully active systems. In conclusion, the paper highlights the advantages of semi-active anti-roll bars in improving driving dynamics and comfort. The technology offers a promising alternative for future automotive applications, providing a balanced approach between performance enhancement and resource efficiency. The study underscores the semi-active system's potential as a viable solution for enhancing vehicle dynamics, especially in mid-range and economy vehicles.
