Abstract
In this study, dynamic modeling of an electrorheological (ER) damper is performedconsidering the unsteady behaviors of ER fluid flow through the annular duct of thedamper. After describing the configuration of the ER damper, quasi-static modeling ofthe damper is conducted on the basis of the Bingham model of ER fluid. Thepressure drop of the unsteady ER fluid flow through the annular duct between theelectrodes of the damper with a known variation of flow rate is then obtained bysolving the momentum equation of the ER fluid flow using the Laplace transformtechnique. Based on the proposed unsteady flow solution, the simulated results areobtained and compared with measured ones in order to evaluate the effectivenessof the proposed model. In addition, in order to reduce the computation load, asimplified solution of the dynamic damping force is proposed with validation.
