| Summary: | In this work we designed and manufactured a novel magnetorheological (MR) fluid damper with internal
pressure control. Previous authors’ works showed that the yield stress τB of MR fluids depends both on the magnetic field
intensity and on the working pressure. Since the increase of the magnetic field intensity is limited by considerations like
power consumption and magnetic saturation, an active pressure control leads to a simple and efficient enhancement of the
performances of these systems. There are three main design topics covered in this paper about the MR damper design.
First, the design of the magnetic circuit; second the design of the hydraulic system and third the development of an
innovative pressure control apparatus. The design approach adopted is mainly analytical and provides the equations
needed for system design, taking into account the desired force and stroke as well as the maximum external dimensions. |
