Abstract: Dynamic vibration absorbers are commonly designed and tuned to suppress vibrations of one vibration mode of a vibrating structure even it is a multi degree-of-freedom (MDOF) or continuous structure. Resonance at other vibration modes of the structure may still occur if the exciting force has a wide frequency band. A subsystem approach is proposed for analysis of the added stiffness and damping of vibration absorbers to the primary structure to which they are attached. The transfer function between the counteracting force from the vibration absorber and the vibration amplitude can then be derived for the comparison of their counteracting forces to the primary system. The major advantage of using the proposed method is that different designs of vibration absorber can be analysed separately from the primary system and therefore the dynamics characteristics of different designs of vibration absorber can be compared efficiently.
