基于MR的船用减振抗冲隔离器试验研究
摘要
提出了一种新型的船用减振抗冲隔离器系统。此隔离器由钢丝绳弹簧和磁流变(MR)阻尼器并联组成
应用MR阻尼器的高阻尼和阻尼可控性使该隔离器的力学性质可控
进而实现协调解决船舶设备的低频减振和高频抗冲击问题。在对隔离器抗冲减振性能的研究中
分别采用了数值试验和模型试验方法
并进行了对比分析。研究结果表明:隔离器系统对振动和冲击响应有较好的控制作用
尤其体现在抑制系统共振和控制系统的低频振动上。
Abstract
A new-style isolator system in ship is presented
which is composed of wire rope and MR damper in parallel.By using 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 shock resistance in high frequency of ship equipment.In the researches on the shock resistance and vibration reduction performances
numerical experiment and physical experiment are carried out respectively
experimental results indicate that the new isolator system has a good active controllable effect on the vibration and shock
especially for controlling resonance and low-frequency vibration of system.
