Paper Abstract

The smart composite beam featuring the electrorheological (ER) fluids which is designed in this paper is composed of three kinds of materials that are structural material, damping material and sealant material. The elastodynamic frequency response characteristics of smart beam are studied in details by using experimental method. The results demonstrate clearly the ability to significantly change the vibration characteristics of beam fabricated in smart composite by changing the electric field intensity imposed on the fluid domains. Meantime, a control algorithm based on fuzzy-like logic are employed in the active vibration control of cantilevered beam featuring electrorheological fluids. The study results are shown that the beam's structural vibration can be controlled more effectively using the proposed active control rule.
