Electromagnetic damper has been given special attention by many researchers and thus is among the important research areas in vibration system. This paper examines electromagnetic damper effect through simulation and experimental study. A vibration test rig incorporating a simple electromagnetic damper is designed and tested to examine the impact of electromagnetic force.The vibration system test rig can be operated as free vibration as well as a forced vibration system. In the simulation phase, the MATLAB model of the electromagnetic damper system is developed, considering its dynamic behavior. This simulation allows for the evaluation of the damper's effectiveness in reducing vibration amplitudes and settling times. Subsequently, an experimental setup is constructed to validate the simulation results. One of the key findings of this research is the comparison of different materials used as the outer cylinder of the electromagnetic damper system. The results indicate that aluminum exhibits a superior damping coefficient value of 2.8 kgs-1 compared to Nylon, which has a damping coefficient of 1.9 kgs-1. This observation highlights the significant impact of the damper's material choice on the vibration system's amplitude and settling time. The implementation of aluminum as the outer cylinder results in reduced amplitudes and quicker settling times in the vibration system. The combination of simulation and experimental studies enhances the understanding of the electromagnetic force's influence and validates the findings. The comparison of different materials for the damper's outer cylinder underscores the importance of material selection in achieving optimal damping coefficients and improved vibration system performance.
