Abstract: This paper proposes and studies a new hybrid semi-active control strategy based on the conventional Rakheja-Sankar (R-S) semi-active control to provide better ride-handling quality for vehicle suspension systems, as well as industrial vibration isolators. This study combines the effect of dampers asymmetry and conventional control strategies to achieve higher performance. A simple one-degree-of-freedom quarter-car model is adopted to study the proposed system. To demonstrate the effectiveness of this new strategy, the analytical method of averaging and the numerical analysis are deployed. In addition, a one-degree-of-freedom test bed equipped with a semi-active magnetorheological (MR) damper is developed. The analytical, numerical and experimental methods confirm the advantages of the proposed strategy over the passive system and the conventional control strategies. This new semi-active control strategy could be easily adopted to be used with most of the existing semi-active control systems, offering a higher level of performance with minimal changes.
