Research on the Mechanics Characteristics of Ship Vibration Reduction and Impact Resistance Isolator Based on MR
In this paper, a new-style isolator system in ship is presented, which is composed of wire rope and MR damper in parallel. By taking advantages of the high damping and damping variability of MR damper, it is possible to make the mechanics characteristics of isolator controllable and then solve the problem of vibration reduction in low frequency and impact resistance in high frequency of ship equipment. In the researches on the impact resistance and vibration reduction performances, numerical experiment and physical experiment are carried out respectively, results indicate that the new isolator has a good active controllable effect on the vibration and impact, especially for controlling resonance and low- frequency vibration of system.
