Finite element analysis of coupled phenomena in magnetorheological fluid devices

摘要

This paper deals with coupled electromagnetic, hydrodynamic and mechanical motion phenomena in magnetorheological fluid devices. The governing equations of these phenomena are presented. The numerical implementation of the mathematical model is based on the finite element method and a step-by-step algorithm. In order to include non-linearity, the Newton-Raphson process has been adopted. A prototype of an electromagnetic brake has been built at the Poznan University of Technology. The method has been successfully adapted to the analysis of this brake. The results of the analysis are presented.
