“…Following similar principles, a damper with single-stage flow mode was also proposed by Aydar in 2010, shown in Figures 32(a) and 32(b) [91]. Unlike the structure mentioned in Figure 31 [80], two coils and a permanent magnet are adopted in this damper so that the magnetic field strength in radial channels can be further enhanced, thus expanding a damping ratio.…”

Owing to unique advantages, magnetorheological fluid (MRF) dampers have been widely adopted in different fields of vibration control. Significant differences of structures occur in diverse fields due to the respective requirements, thus obtaining a large number of MR dampers. Having a good understanding of types, technical characteristics, comprehensive performance, and developing trend and their dependencies on structures are extremely conducive to innovative developments and a market selection. While the fundamental and partial structures are summarized in an existing review, the classification, latest technologies, and developing trend are not involved clearly. Therefore, the current survey aims at a comprehensive supplement in such aspects. The review begins with an introduction of the development, application, and classification. Then, details of three technical routes are revealed, and the development of each type is roughly analyzed. Finally, reflecting through this review, structures including a novel flow mode and miniature bypass valves have represented the currently structural and technical features. Fully considering the latest technologies and future requirements, the developing trend and a variety of applications will be anticipated.

“…The device was designed to engage and disengage a power brake vacuum pump from a diesel engine. A Two-way MR fluid valve using a permanent magnet and a coil was discussed in [3]. The drawback of this design was the location of the permanent magnet that required the rated current of the coil to be carefully chosen in order not to outdo the coercivity of the PM.…”

In this paper, we present a new concept for generating magnetic field in Magneto-Rheological (MR) clutches intended for safe robotic applications. The main rationale behind this concept is to divide the magnetic field generation into two parts using an electromagnetic coil and a permanent magnet. The permanent magnet generates a bias magnetic field density at the optimum working point of the MR clutch while the energized coil can add or negate the magnetic field to a desired value. The results will show clear advantages of this concept in reducing the total weight of the MR clutch, improving the torque-to-mass ratio, and reducing electrical power consumption. The proposed concept is validated using computer model of an MR clutch and Finite Element Method (FEM) is hired to compare the characteristics of the proposed MR clutch with those from conventional coil based clutch. Experimental results will be provided to further validate the advantages of the proposed new concept.

“…As an alternative to these solutions, an exciter system, based on permanent magnets (PM), can be used. However, very few solutions using such kind of excitation have been developed in the past [31]- [40]. Although some of these devices operate quite well, some configurations present drawbacks.…”

“…In [40], the authors have explored the possibility of using a combined PM-coil exciter in order to control the magnetic field inside the fluid. The system is arranged to operate as follows: the MR clutch transmits the torque by using only the bias field of a permanent magnet that assures the fluid proper excitation (in this condition the coil is not fed).…”

This paper describes the magnetic design of an innovative fail-safe clutch based on magnetorheological fluid (MRF). A cylindrical arrangement of permanent magnets (PMs) is used to excite the fluid. The suitable distribution of magnetic field inside the MRF and the transmissible torque is obtained by moving the PMs along the axial direction. The device is designed using a magneto/mechanical FEM model, developed on purpose and based on a three-dimensional (3-D) finite-element code, which takes into account the B-H and τ -H functions of the nonlinear materials (e.g., MRF, PM, and ferromagnetic materials). The flux density maps and the shear stress maps inside the fluid are carefully analyzed. Furthermore, in order to validate the FEM model, some preliminary experimental measurements are performed on a prototype. Finally, the magnetic axial force acting on the PM system is investigated.Index Terms-FEM analysis, magnetorheological clutch, permanent magnets.
