Abstract:

磁流变弹性体(MRE)由于其力学性能稳定且有显著的磁流变效应,在平台结构智能隔振控制方面具有广阔的应用前景。本文首先通过动态试验研究了溴化丁基橡胶基磁流变弹性体(BIIR_MRE)的力学性能,该材料具有良好的耗能能力和磁致变刚度特性;然后根据试验结果及平台参数设计了一种采用MRE材料的隔振支座,并以平台竖向加速度为控制量设计了相应的PID控制系统;最后在Simulink中建立仿真模型验证了隔振支座的隔振效果。仿真结果表明该隔振控制系统可以有效地降低平台的竖向加速度、速度和位移响应;控制力饱和可能造成加速度和速度响应的跳跃,故控制力是限制PID控制系统隔振效果的主要因素;提高MRE的磁流变效应,可以进一步改善PID控制效果。
