Paper Abstract

This paper presents dynamic modeling and shape control of a smart plate filled with an electrorheological (ER) fluid. Firstly, a dynamic model incorporated with complex shear modulus of the ER fluid itself is developed to estimate field-dependent modal parameters of the plate structure via finite element approach. Following a construction of a four partitioned ER fluid-based plate, an extensive modal test is experimentally conducted to identify modal parameters with respect to both the magnitude and the area of the applied electric fields to the ER fluid domain. In order to validate the effectiveness of the proposed smart plate, globally and locally controlled mode shapes and natural frequencies are investigated. Both the experimental and analytical results indicate that the ER fluid imbedded in the distributed- parameter system of plate-like structures has a great authority in tuning structural shapes and elastodynamic properties.
