Generally, a moving system will typically produce vibrations when it is moving in rectilinear or rotating and it is common for the unbalanced motor to produce high vibration intensity when it is operated. This vibration is very harmful to the motor’s lifespan and to its operations. Therefore, it is very important to control and reduce the vibrations produced by the unbalanced motor during operation. One of the popular methods of doing this is using dynamic vibration absorbers (DVAs). DVA is an efficient control device that is connected to a vibrating system to reduce undesired vibrations by equalizing its excitation frequency to nearly coincide with the natural frequency of the primary system. This can be achieved by tuning the DVA parameters to the optimal value. This research is aimed at designing and developing a tuneable dynamic vibration absorber (TDVA) to reduce the unbalanced motor vibration by optimizing the DVA parameters. The optimal DVA parameters have been computed directly using dynamic properties of the primary system by assuming the unbalanced motor to be the single degree of freedom vibration system. The results of this study indicate that the total vibration reduction gained by the unbalanced motor when using DVA is about 96.85% where the initial amplitude of the motor before and after the DVA attachment is 4.13 m/s2 and 0.13 m/s2. This has shown that the designed TDVA is operating as anticipated because it was able to successfully reduce the amplitude.
