Research on the Dynamic Characteristics of a Controlled Magnetorheological Elastometer Damper

Abstract

The design of a controlled damper on the basis of a magnetorheological elastomer is described. The technique of determining the dynamic characteristics of the damper, such as the stability, the time constant, and the positioning error, in an active step-by-step displacement mode is presented. A dynamic model of the automatic-control system of the controlled damper is described. The results of experimental studies of the damper start-off current, which amounted to 0.05 A, and the transient process during movement from one point to another (the error does not exceed 2 μm) are presented.
