A method for reducing vibration of a sandwich structure using the antiresonance technique is presented. It is found that with appropriate resonators, the motion of the sandwich structure due to disturbances with certain frequencies can be effectively suppressed. A simple two-degree-of-freedom system consisting of an absorbing mass connected by springs to a drive mass is introduced and used to interpret the vibration behavior of the sandwich structure with resonators.
