Abstract

Abstract: Aiming at the vibration characteristics of a small type steel frame, based on the theory of non‐Newton liquid, from the physical property of the magneto‐rheological fluids, the shear stress model of magneto‐rheological fluids damper is built up, the non‐linear characteristics of the magneto‐rheological damper is described, and the parameters of designed magneto‐rheological damper are obtained. The vibration characteristics of the frame structure is studied using magneto‐rheological damper, the results show that after the magneto‐rheological fluids damper fixed, the vibration response of the frame structure is decreased by 42 % for the first mode, which validates the damping effect of the developed magneto‐rheological damper, which provides the theoretical and experimental proof for the design of magneto‐rheological damper.
