Magneto-rheological (MR) materials and their devices are being rapidly developed and have drawn surge of interest for the potential application in vibration control. Among them, a novel shear-mode rotational MR damper (SM-RMRD) with adaptive variable stiffness and damping was developed for adaptive structural control in real-time against different types of earthquakes. To make use of this innovative device perfectly, a robust and reliable model should be developed to simulate the nonlinear and hysteretic behaviours for the application in adaptive control. Accordingly, this research initially presents a new phenomenological model to describe the force response of the SM-RMRD. Then, model parameters are estimated based on experimental data of force, displacement and velocity, which were directly or indirectly obtained from the device under different loading protocols. The field dependence of each model parameter is also investigated so that a general model with current-related par...

剪切模式旋转MR阻尼器的动态建模和控制，以减轻建筑结构的危险振动

磁流变（MR）材料及其设备正在迅速发展，并引起了人们的兴趣，它们在振动控制方面有潜在的应用。其中，开发了一种新型的具有自适应可变刚度和阻尼的剪切模式旋转MR阻尼器（SM-RMRD），用于针对不同类型的地震实时进行自适应结构控制。为了完美地利用这种创新的设备，应该开发出鲁棒且可靠的模型来模拟非线性和滞后行为，以用于自适应控制。因此，这项研究最初提出了一种新的现象学模型来描述SM-RMRD的力响应。然后，根据力，位移和速度的实验数据估算模型参数，这些是在不同的加载协议下直接或间接从设备获得的。还研究了每个模型参数的场相关性，从而使具有电流相关参数的通用模型...
