The multiplication of Dynamic Vibration Absorbers (DVAs) has been studied for several years to improve is performance. However, the optimal regulation of DVA becomes practically difficult for increasing of number of DVAs. In the paper, multi-series-mass DVA has been studied to improve vibration control performance and regulation easily. The optimal parameters of two-series-mass DVA and three-series-mass DVA have been calculated for compliance optimization, so that optimal design diagrams shall be conducted. The performance of vibration control is analyzed through the simulation and experiment. The results show that the two-series-mass DVA improves its performance, in the same ratio, by about 20% than the one-mass DVA, by about 11% than the two-parallel-mass DVA; while the three-series-mass DVA improves its performance, in the same total mass ratio, by about 25% than the one-mass DVA, by about 11% than the three-parallel-mass DVA; and both they show better results than the four-parallel-mass DVA.
