Abstract: Dual Translational dynamic vibration absorber (d-DVA) is two DVA masses that can move in the translational direction and given into the system to reduce system translation translational vibrations. In this research we conducted a study related to the characteristics of 2 DOF system vibration response after the addition of dual translational DVA with an experimental approach and compared the results with simulation results data. The research shows that the addition of dDVA causes the system to have twice natural frequency that occurs at rf = 0.92 and rf = 1.09. The RMS values were 9.81 m s2 and 15.25 m s2 respectively. The error between the simulation and experimental results is 8.5 which is caused by the propagation some of the vibrational energy from the system to the surrounding environment.
