摘　　要：电流变流体是一种新型的智能材料,在工程中有广泛的应用前景。本文利用自行设计的测试装置通过对测杆振幅、共振频率等参数的测定,研究电场作用下电流变流体刚度及阻尼变化。根据实验研究提出变参数的粘弹阻尼力学模型,描述电流变流体在电场作用下附加阻尼和附加刚度。ERF is a type of new intellectual material which has a broad application prospect in the field of engineering. In this paper, a testing device is designed to study the change of stiffness and damping of ERF under electric field, by testing the parameters as the amplitude and resonance frequency of reference rod.Based on the experiment, variable parameters viscoelastic mechanical model describing the additional damping and stiffness under the effect of electric field is put forward.
