  • This paper deals with the vibration reduction of hull mount system of ship structures brought by ER smart structures. The hull mount is used to isolate the vibration of equipment from the host structures. Utilizing the tunable characteristics of ER fluids, ER inserts are made in the hull mount structure. Different types of ER inserts are proposed and the vibration characteristics are investigated. A hull mount structure is made and the influence of ER inserts are experimentally studied. An extensive modal test is empirically conducted to identify natural frequencies and mode shapes according to the applied electric field and the types of ER insert. The frequency tunable characteristics of ER inserts can be applied to many mounting structures for vibration reduction.
