Design 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 کاملCharacterization and Modeling of Symmetric and Asymmetric Damping Properties of a Magnetorheological Damper
For realizing the intelligent vehicle suspension design with magneto-rheological (MR) fluids dampers, extensive laboratory measurements are performed to characterize the symmetric and asymmetric hysteresis force properties of a MR-damper, under a wide range of drive current and harmonic excitation conditions (frequency and stroke). The proposed asymmetric damping force generation (ADFG) algorit...

متن کاملPreliminary Study of Modelling Dynamic Properties of Magnetorheological Fluid Damper
u(t) c 1 2 k 3 m f c 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...
متن کاملVariable stiffness and damping MR isolator
This paper presents the development of a magnetorheological (MR) fluid-based variable stiffness and damping isolator for vibration suppressions. The MR fluid isolator used a sole MR control unit to achieve the variable stiffness and damping in stepless and relative large scope. A mathematical model of the isolator was derived, and a prototype of the MR fluid isolator was fabricated and its dyna...
