Damped dynamic vibration absorbers are adopted to attenuate multi-mode longitudinal vibration of the hollow shafting, the dynamic model of the shafting with multiple dynamic vibration absorbers is established using the transfer matrix method, combined with the substructure synthetic method, and the dynamic behavior of the shafting under harmonic excitation is analyzed. Considering the coupling behavior of dynamic vibration absorbers, the parameters of the dynamic vibration absorbers are optimized, regarding the mean square of the displacement response in a targeted frequency range as an object function. Based on the hollow characteristic of the shafting, a specific structure of dynamic vibration absorber is designed, and finite element stimulation is used to verify to the theoretical calculation. The research results showed that the resonance peak is strongly attenuated and the frequency response function curve turned to smooth when multiple dynamic vibration absorbers attached to the shafting, furthermore, the absorption effect is improved after an optimization of dynamic vibration absorbers.
