“…One of the merits of this structural configuration is to have a smooth flow motion of MRF in the gap since there is no obstruction in the flow path. The second type of MRF damper was fabricated on the basis of the squeeze mode (Yazid et al, 2014). One salient property of this type, is to have a high damping force compared with the type of the flow mode.…”

This paper presents a mini-review of magnetorheological (MRF) fluid-based devices (MRF devices in short) including the brake, clutch, damper, and the mount reported from 2013 to 2018. MRF devices are usually designed based on three operating modes of MRF: flow mode, shear mode and squeeze mode. Each mode has its own characteristics for the high performance of application systems. Therefore, numerous design configurations of MRF devices have been proposed by many researchers. In this article, among many different MRF devices such as MRF brake, clutch, damper and MRF mount proposed over the last 6 years are examined in the sense of their structural configuration and operating principles. Certain advantages and demerits of each MRF device are also discussed. In addition, some useful design guidelines of MRF devices, which are absolutely different from developed MRF devices so far, are provided to enhance design simplicity and control performance.

“…shows the magnetic flux density variation along an imaginary pathway that is assumed in the middle of the MR fluid gap, which starts from a level parallel to the top end of the piston and ends at a point that is level with the lower end of the piston. The results in this figure (obtained for the same current density of 16,000 kA/m 2 ) show that the magnetic flux drops sharply within the centre part of the fluid volume that is opposite the electromagnetic coil element, which is an issue that was also encountered with the development of other MR fluid devices[27][28][29].…”

Single-port laparoscopic surgery (SLS), which utilizes one major incision, can deliver favorable cosmetic outcomes with fewer patient hospitalization stays and less postoperative pain. However, current SLS instruments, which are rigid and slender, have been suffering from several drawbacks, including their inability to provide the optimum articulation required to complete certain SLS tasks. This paper reports on the development of a lightweight smart hydraulic actuation system that is proposed to be embedded at selected joints along current SLS instruments, in order to enhance their adaptability with a higher level of stiffness and degrees-of-freedom. The developed smart actuation system utilizes both conventional hydraulic and magnetorheological (MR) fluid actuation technologies. Electromagnetic finite element analyses were conducted to design the electromagnetic circuit of the smart actuator. A prototype of the developed actuation system was manufactured, and its performance was assessed using a dedicated experimental arrangement, which was found to agree well with the results obtained using a Bingham plastic theoretical model. Finally, the present design of the developed smart actuation system permits an angulation of about 90° and a maximum force output in excess of 100 N, generated under a magnetic excitation of about 1.2 Tesla, which should be sufficient to resist torques of up to 500 mNm.

“…MRF is a fluid composed of a carrier fluid, such as silicone oil and iron particles, which are dispersed in the fluid [2,3], with an ability to alter its basic characteristics and viscosity, when subjected to the magnetic field. [4]. Upon applying a magnetic field, the tiny polarizable particles in MRF make chains between two poles, as shown in Figure 1 [6].…”

The magnetorheological fluids (MRF) are a generation of smart fluids with the ability to alter their variable viscosity. Moreover, the state of the MRF can be switched from the semisolid to the fluid phase and vice versa upon applying or removing the magnetic field. The fast response and the controllability are the main features of the MRF-based systems, which make them suitable for applications with high sensitivity and controllability requirements. Nowadays, MRF-based systems are rapidly growing and widely being used in many industries such as civil, aerospace, and automotive. This study presents a comprehensive review to investigate the fundamentals of MRF and manufacturing and applications of MRF-based systems. According to the existing works and current and future demands for MRF-based systems, the trend for future research in this field is recommended.
