“…When 2 degrees of freedom of the system are subjected to a harmonic force, the system will produce a response similar to a single degree of freedom [12]. Resonance occurs when the excitation force frequency matches the natural frequency of the system [13]. A dynamic vibration damper is a mechanical device used to reduce or eliminate mechanical vibrations [14].…”

Two mass absorber is a vibration control system designed to enhance structural stability by strategically placing additional masses to effectively absorb and dampen vibrations. This technology mitigates resonance and harmful amplitude, reducing the risks of structural failure and operational inefficiencies in diverse engineering applications. Through this innovative approach, structures can withstand dynamic forces and operate efficiently in various fields. The TM 150 unit is used for conducting various experiments related to vibration phenomena. In this paper, experiments are carried out on a flexible beam that is oscillated using an unbalanced mass in the frequency range of 6 Hz to 18 Hz to see at which frequency the flexible beam will resonate. Another variation is to provide two mass absorbers under the flexible beam to see the difference. The experimental resonance graph was produced that was in accordance with the theoretical one, but with different amplitude units due to equipment limitations. The resulting graph shows before the absorber, the flexible beam resonates at its natural frequency. Afterward, small vibrations occur at that point, while resonance shifts. Furthermore, the performance of the vibration test unit is very good in showing the phenomena that occur in accordance with the theory.
