The multiplication of Dynamic Vibration Absorbers (DVAs) has been studied for several years to improve its performance. However, the optimal regulation of DVA becomes practically difficult for increasing of number of DVAs. In this paper, two-series-mass DVA has been studied to improve vibration control performance and regulation easily. The optimal parameters of two-series-mass DVA have been calculated from compliance optimization, accelerance optimization and mobility optimization, so that optimal design diagrams and approximately formulas 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 total mass ratio, by about 20% than the one-mass DVA, and also it shows better results than even the four-parallel-mass DVA.
