- The vibration on structures and machines is difficult to avoid. The vibration absorber can be used to minimize the amplitude. Structural dynamic modification technique can be applied for vibration absorber, but this technique need much of parameters (constraint function) and need high ability, times and high cost. The limitation can be reduced using dynamics absorber, so modification can be done easier without change the prime structure (absorbing structure). This research is done using theoretical and experimental. The results of this research are satisfied, the trend of the analytical results is in good agreement with experimental. Eigen frequency of cantilever after using spring-mass system is move to left and right, and the amplitude can be reduced on the same rotational speed. Theoretically, the amplitude of structure can be made zero but experimentally can be reduced up to 99%. The dynamics modification with change of the different spring can be raise the reduction of the amplitude, for first technical data 98.52% and for second technical data 99%.
