Multiphysics modeling of magnetorheological dampers
The International Journal of Multiphysics, 2013 The dynamics of a small scale magnetorheological damper were modeled and analyzed using multiphysics commercial finite element software to couple the electromagnetic field distribution with the non-Newtonian fluid flow. The magnetic flux lines and field intensity generated within the damper and cyclic fluid flow in the damper under harmonic motion were

Advanced Robotics Research, EarlyView.Permanent magnet putty (PMP) integrates high‐coercivity NdFeB particles with a dynamic polyborosiloxane–Ecoflex matrix, achieving rapid self‐healing (90% mechanical recovery in 10 s) and magnetic recovery within 20 min. With twice the sensitivity of commercial putties, PMP enables precise 5–30 N force detection and discrimination between pressing and ...

Fast, Strong Capillary Liquid Metal Muscles
Advanced Intelligent Systems, EarlyView.Capillary liquid metal muscles (CLMMs) harness the exceptionally high and electrochemically tunable surface tension of gallium‐based liquid metals (e.g., EGaIn) to generate mechanical work. Confinement within microchannels maximizes surface‐energy conversion, enabling high force, ultrafast response (<25 ms), low‐voltage operation (<10 V), and ...

Dynamic model for a magnetorheological damper
Applied Mathematical Modelling, 2014 Abstract A lumped mass thermo-mechanical model for the dynamics of a damper filled with a magnetorheological fluid is described, analyzed, and numerically simulated. The model includes friction and temperature effects, and consists of a differential inclusion for the piston displacements coupled with the energy balance equation for the temperature ...

A Technological Review of Magnetorheological Dampers
International Journal of Advanced Research in Engineering Innovation, 2021 Damper is part of suspension system where it is function to prevent noise, bumps, and vibrations. Most dampers are categorized in three categories which is active, semi-active and passive damper. Magnetorheological (MR) damper is categorized under semi-active damper.
