Abstract: In this paper, we study the vibration of multi-degree of-freedom systems added dynamic absorbers and present an optimum design method to dynamic absorbers. According to the different requirements of design, the optimum dampings and springs of absorbers can be chosen in multiple meanings. Lagrang’s interpolation is used for calculating transfer functions; and hence the difficulties of theoretical or numerical calculating the transfer functions are solved. Examples show that this method is effective.
