This study presents a comprehensive assessment of the MR damper RD-8041-1, evaluating its performance and suitability for a semi-active suspension system. The MR dam per RD-8041-1is investigated in a damping testing machine at different current levels (ranging from 0 to 2 A in increments of 0.5 A) and velocity ranges (0.05, 0.13, 0.27, 0.39 and 0.52 m/s) on key performance metrics, including energy dissipation, the equivalent damping coefficient and peak damping forces. The findings indicate that the MR damper effectively responds to variations in current input, with elevated currents resulting in greater damping forces and enhanced energy dissipation. Energy dissipation increased by 562% during the extension stroke when the current input was increased from 0 A to 2 A. The damping force saw a significant increase, with a 332.38% rise during the compression stroke at a velocity of 0.05 m/s when current input was increased from 0 A to 2 A. Frequency studies indicated that the MR damper operates most efficiently within the frequency range of 2 to 6 Hz at a peak current of 1 A, and within 2 to 5 Hz with a peak current of 2 A. The damper's response time indicated its ability to manage rapid oscillations, making it suitable for dynamic environments. The MR damper RD-8041-1 exhibits significant potential for use in semi-active suspension systems, offering enhanced ride comfort, stability, and energy efficiency by adapting to diverse road conditions and driving situations.
