Longitudinal vibration control of ship propelling shaft system was studied. The idea of a new-type dynamic vibration absorber (DVA) was put forward based on the structural characteristics of the smart material of magneto-rheological elastomers (MRE). A new-type broad frequency absorber was designed, employing the characteristic of stiffness adjustable of MRE material, to realize the effective control of the longitudinal vibration of the ship shafting system under variable operating conditions. A semi-active control absorber for the shaft system was processed, and the frequency shift effect was measured. The experiment results agree well with the theoretical analysis. This idea is verified. It is of directive significance for engineering design and application of the dynamic vibration absorbers.
