摘　　要：为了验证MR阻尼器在强迫振动下对拉索进行半主动控制的效果,本研究采用RD-1005-03型MR阻尼器,以通用设计曲线为基础,并基于Simulink系统编制半主动控制算法程序框图,实现正弦荷载强迫振动下的拉索MR阻尼器系统的半主动控制仿真。根据所提出的半主动控制算法,计算拉索-MR阻尼器系统的动力响应。最后,结合各测点处加速度的均方根值,评价半主动控制的效果。In order to verify the semi-active control effect of MR damper on cable under forced vibration,rd-1005-03 MR damper is used in this study.Based on the general design curve and Simulink system,the program block diagram of semi-active control algorithm is compiled to realize the semi-active control simulation of cable MR damper system under sinusoidal load forced vibration.According to the proposed semi-active control algorithm,the dynamic response of cable MR damper system is calculated.Finally,combined with the root mean square value of acceleration at each measuring point,the effect of semi-active control is evaluated.
