利用黏-弹-塑性模型对磁流变阻尼器动力学性能预测与分析
Prediction and Analysis of Dynamic Performance of Magnetorheological Damper with Visco-elasto-plastic Model
摘要
Abstract
In order to exploit the advantages of semi-active vibration control of magnetorheological dampers,it is need to establish a suitable parametric model to study the dynamic output characteristics of the damper.The research work in this paper is under the conditions of 5 Hz excitation frequency and 10 mm amplitude,using the vibration system to test the magnetorheological damper under eight levels of excitation currents to obtain the dynamic output characteristics.On this basis,the visco-elastic-plastic parameter model is used to predict the actual measurement results under all currents using the drosophila optimization algorithm.The research results show that the output force of the damper can follow the change of the external displacement with time.The damping force increases slowly and then significantly increases with the increase of the excitation current,which shows that the damper depends on the controllability of the input current,which provide conditions for the realization of semi-active control in engineering applications.The reason for this phenomenon is caused by the interaction between the particles and the matrix under different currents.The prediction results show that the visco-elastic-plastic parameter model can describe the actual measurement result well using the drosophila optimization algorithm.关键词
