Phenomenological Model of a Magnetorheological Damper
Semi-active control devices have received significant attention in recent years because they offer the adaptability of active control devices without requiring the associated large power sources. Magnetorheological (MR) dampers are semi-active control devices that use MR fluids to produce controllable dampers. They potentially offer highly reliable operation and can be viewed as fail-safe in th...
متن کاملA novel model of magnetorheological damper with hysteresis division
Due to the complex nonlinearity of magnetorheological (MR) behavior, the modeling of MR dampers is a challenge. A simple and effective model of MR damper remains a work in progress. A novel model of MR damper is proposed with force-velocity hysteresis division method in this study. A typical hysteresis loop of MR damper can be simply divided into two novel curves with the division idea. One is ...
متن کاملDesign and Evaluation of a Magnetorheological Damper Based Prosthetic Knee
In this work, a magnetorheological (MR) damper based above-knee prosthesis is design and evaluated based on its performance in swing phase and in stance phase. Initially, a dynamic system model for swing phase of a prosthetic leg incorporating a single-axis knee with ideal MR damper was built. The dynamic properties of the damper are represented with Bingham parametric model. From Bingham model...
متن کاملDynamic Magnetorheological Damper for Orthotic Tremor Suppression
This paper explores the design methodology and effectiveness of small-scale magnetorheological dampers (MRDs) in applications that require rapidly variable damping. Previously applications of MRDs have been chiefly limited to vehicle shock absorbers and seismic vibration attenuators. There has been recent biomedical interest in active-damping technology, particularly in the field of rehabilitat...
متن کاملHysteresis modeling for the rotational magnetorheological damper
Vibrations is an extremely important issue to consider when designing various systems. It may lead to discomfort and malfunction or in some cases collapse of structures. To compensate for these vibrations different types of damping devices can be applied. The main focus which the following work addresses has been to look at standard methodology which enables determining the hysteresis from defi...
