Preliminary Study of Modelling Dynamic Properties of Magnetorheological Fluid Damper

    Research output: Book/ReportReport

    Abstract

    A preliminary study was conducted to investigate numerical models that can be used to simulate the dynamic behaviour of a damper based on magnetorheological (MR) materials. Several articles presenting the results of experimental testing and mathematical modelling have been published recently. The goal for this study was to implement a selected model into the finite element method (FEM) for structural dynamic analysis purposes in the time domain. A simplified controllable spring-dashpot-friction element was implemented as a user element subroutine ("smart connector element") into the ABAQUS/Standard FEM-program. The model was verified by numerical comparisons. It was observed that the smart connector element can be applied to simulate a similar dynamic response to that measured in the experiments. Therefore, it can be employed to analyze adaptive structures in which the MR-damper is utilized to control dynamic properties.
