“…Still considering the advantages of a radial flow mode and a bypass valve, a damper in a suspension system of a high-speed train had been designed by Guo et al, shown in Figure 36 [28,93]. One-way valves in a piston and the foot valve are helpful to form a flow along a single direction.…”

“…In recent past 15 years, MR dampers have been widespread in different fields of vibration control [7,8] including, but not limited to, the civil buildings and bridges [9][10][11], suspension systems in high-speed trains [12][13][14], advanced artificial limb system [2,15], large washing machine [16,17], automotive suspension systems [18][19][20][21], aircraft landing gear [22,23], seats of commercial vehicle [24,25], complex mechanical systems [26], helicopter rotor system [27], and so on. e survey including the above literature would report that, although MR dampers have unique advantages such as continuous damping control, short response time, and large yield stress under smaller voltage [28][29][30], an available product in market is usually depended on a single coil [31] embedded in a piston groove. is structure brings obvious deficiencies in the effective damping channel, magnetic field utilization, adjustable damping range, versatility, manufacture and heat dissipation, etc.…”

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 properties of MR damper can be changed by changing applied current [1]. MR damper have been chosen over a decade for vehicle suspension system [2][3][4], helicopters seat [5], civil structure base isolation [6][7][8], and railway transport [9,10]. Semi-active MR damper is especially applicable for unpredictable motion conditions and capable large payload condition.…”

A design methodology for a magnetorheological fluid damper based on a multi-stage radial flow mode C R Liao, D X Zhao, L Xie et al. The static piston coil case is winding by a coil which is used inside the piston head arrangement. The current controlled coil case provides a magnetic flux through the BMRD cylinder for controllability. The high strength of alloy steel materials are used for making piston shaft which allows magnetic flux propagation throughout the BMRD cylinder. Using the above design materials, a Bypass MR damper is designed and tested. An excitation of current is applied during the experiment which characterizes the BMRD controllability. It is shown that the BMRD with external flow channel allows a high controllable damping force using an excitation current. The experimental result of damping force-displacement characteristics with current excitation and without current excitation are compared in this research. The BMRD model is validated by the experimental result at various frequencies and applied excitation current.

“…MR fluids are attractive because they provide a simple and rapid response interface between electronic controls and mechanical systems. MR damper is used in automotive industry (Nguyen, 2009), for the control of seismic vibrations in buildings (Yang, 2002), in railway industry (Guo, 2014) or for damping in stay cable bridges (Choi, 2007). MR damper provides high force dynamic range, is reliable and has low energy consumption (Yang, 2002).…”
