In the case of carrying heavy cargo, which tends to be easily damaged by vibration caused by a vehicle or a ship during transportation, stopping the vibration of the board loaded with the cargo is achieved by means of hydraulic servomechanisms which are placed between the board and the hull. However, the behavior of a hydraulic servomechanism under a vibrating condition differs from that of a hydraulic servomechanism on a stationary base. The aims of this research are to stop the apparent movement of a massive load (vibration insulation) and to clarify the behavior of the hydraulic servomechanism under the vibrating condition. In this paper, the effectiveness of vibration insulation is shown for sinusoidal input and an earthquake-waveform input through the use of an experimental apparatus, and the stability of the servomechanism on the vibrating table is also discussed analytically and experimentally. Experimental and analytical results show good agreement, and the appropriateness of this analytical method is confirmed.
