To reduce the vibration transferred from vessel equipment to the base, a kind of generalized mass-spring damper was proposed. The structure was introduced, and the dynamical characteristic was analyzed by the mobility synthesis method. In order to verify the vibration reduction effect of the generalized mass-spring damper, the lubrication oil pump on the vessel was taken as an analytical object, which rigid-flexible coupling model was established, the frequency and time responses of the acceleration with and without the generalized mass-spring damper were calculated. The results showed that the generalized mass-spring damper can not only reduce the vibration of the equipment feet at a specific frequency, but also suppress the middle and high frequency vibration.
