THEORETICAL RESEARCH OF MECHANICAL BEHAVIOR OF MAGNETO-RHEOLOGICAL FLUID

Abstract

This paper is intended to research of mechanical behaviour of magneto-rheological fluid in magnetic field. This liquid is with highly non-linear properties in magnetic field and their mechanical behaviour cannot be obtained directly. Additional pressure generated by magnetic field strength causes change of magneto-rheological fluid sur-face, therefore the system can be treated as mechanical. There is presented algorithm of evaluation of researched liquid additional pressure from magnetic field influence, which is caused by current in the solenoid. There is algo-rithm and method proposed how finite element method can be used to find additional pressure. The results of this solution give understanding of additional pressure characteristics of magneto-rheological fluid and possibility to use it for magnetically driven mechanical drive. Finally, conclusions on results are made.
