磁流变弹性体隔减振装置是一种智能隔振和减振装置,其参数可随着外界磁场的变化而变化,因此如何根据被控系统的动态特性准确产生磁流变弹性体装置的控制电流是其有效实现对被控系统隔振和减振的关键因素之一。为此,本文以STM32微处理器为核心处理器,研制了一种基于被控系统加速度响应的磁流变弹性体隔减振装置核心控制器,并对该控制器进行了系列静态和动态试验。试验研究结果表明,本文研制的基于被控系统加速度响应的磁流变弹性体隔减振装置的核心控制器,能够准确地输出相应的控制电流。

Design and testing of controller for magnetorheological elastomers vibration isolation and mitigation device

The magnetorheological elastomer (MRE) vibration isolation and mitigation device is an intelligent vibration isolation and vibration mitigation device, whose parameters can change with the change of external magnetic field. Therefore, how to accurately generate the control current of the MRE device according to the dynamic characteristics of the controlled system is one of the key factors to realize the vibration isolation and vibration mitigation of the controlled system. In this work, STM32 microprocessor is adopted as the core processor, and a core controller for the MRE vibration isolation and mitigation device is developed based on the acceleration response of the controlled system. The static and multi-condition dynamic tests of the controller are carried out. The results show that the core controller of the MRE vibration isolation and mitigation device based on the acceleration responses of the controlled system can accurately output the corresponding control current.
