Experimental Study on Ship Equipments Vibration Reduction Based on Magnet or heological Damper

摘要

The equipment vibration on ship is a disadvantage for the operation and safety. It should be reduced to as small as possible. To address this problem, a vibration reduction isolator system based on magnetorheological damper (MR damper) was proposed in this paper. And its experiment was carried out. The vibration experiment was designed using MTS hydraulic loading system. Many load cases were applied in the experiment with different mass of the model, exciting forces, and controllable current of MR dampers. The experiment results indicated that this isolator system has a good performance on vibration reduction of ship equipments, especially near the natural frequency of the system.
