Shock and Vibration, Volume 2023, Issue 1, 2023., 2023 The failures of steel guides can excite complex and intense transverse oscillations of hoisting containers in the mine hoisting process. The present paper mainly contributes to reveal the response characteristics of the transverse oscillations of mine conveyances excited by various faults such as interface misalignment, local bulge, orbital gap ...

A contribution to the analysis of magnetorheological brake
IOP Conference Series: Materials Science and Engineering, 2018 Greater braking torque, in constrained volume and weight, is a primary challenge in magnetorheological brakes' designs. This paper deals with the feasibility of increasing the overall braking torque by multiplying the number of its active surfaces in constrained volume. Improved design of magnetorheological brake is presented.

Effect of Pole Head Profile on Torque Performance of a Disc-Type Multipole Magnetorheological Brake
Applied Sciences, 2023 A magnetorheological brake (MRB) works on the shearing effect of MR fluid in the magnetic field to develop resistance between the stator and the rotor, which are relative moving surfaces.

Design of magnetorheological brake for forearm rotation of a wrist prosthesis
2022 International Conference on Rehabilitation Robotics (ICORR), 2022 A wrist joint in upper limb prostheses significantly increases its handling capacity. However, current prostheses cannot reproduce the ability of torque combined with the volume and weight of the human wrist. Consequently, they do not provide high efficiency in handling and generate user dissatisfaction.

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 ...

The behaviour of magnetorheological fluids in squeeze mode [PDF]
, 2008 Magnetorheological (MR) fluids possess rheological properties, which can be changed in a controlled way. These rheological changes are reversible and dependent on the strength of an excitation magnetic field.

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT To address the dual challenges of routine driving vibration and impact loads in vehicle seat suspensions, a novel variable‐gap magnetorheological damper (VGMRD) is proposed. By combining a tapered piston with a conformal variable‐diameter cylinder, stroke‐dependent, dual‐mode damping characteristics are achieved without the need for complex ...
