Magnetorheological fluid dampers: A review on structure design and analysis

Abstract

Magnetorheological fluid technology has gained significant development during the past decades. The application of magnetorheological fluids has grown rapidly in civil engineering, safety engineering, transportation, and life science with the development of magnetorheological fluid–based devices, especially magnetorheological fluid dampers. The magnetorheological fluid dampers could offer an outstanding capability in semiactive vibration control due to excellent dynamical features such as fast response, environmentally robust characteristics, large force capacity, low power consumption, and simple interfaces between electronic input and mechanical output. To address the fast growing demand on magnetorheological fluid damping technology in extensive engineering practices, the state-of-the-art development is presented in this article, which provides a comprehensive review on the structure design and its analysis of magnetorheological fluid dampers (or systems). This can be regarded as a useful complement to several existing reviews in the recent literature on magnetorheological fluids technology, magnetorheological fluid applications, modeling of magnetorheological fluids and dampers, control strategies of magnetorheological fluid systems, and so on. The review begins with an introduction of the basic features and relevant applications of magnetorheological fluids. Then several basic structure design issues of magnetorheological fluid dampers are introduced. Following this, typical magnetorheological dampers are discussed according to the arrangement configurations of magnetorheological fluid cylinders and magnetorheological fluid control valves. Furthermore, reinforced structure designs of magnetorheological fluid dampers are provided, which focus on coil configuration, fluid resistance channel design, and electromagnetic design. Thereafter, design issues of magnetorheological fluid damper systems are discussed, which involves sensor-based magnetorheological fluid damper systems, self-powered magnetorheological fluid damper systems, fail-safe magnetorheological fluid damper systems, and integrated spring magnetorheological fluid damper systems. Importantly, to have a systematic quantitative viewpoint of the analysis and design of magnetorheological fluid dampers, the review ends with a summary of performance analysis issues, including performance specification, analytical modeling, parameter optimization, and so on.

Complex Fluids in Energy Dissipating Systems

“…Some interesting references on the applications of active-fluids in dampers or shock absorbers can be found in [77][78][79][80][81][82] for ERFs and in [83][84][85][86][87][88][89][90][91][92][93] for MRFs. Additionally, Zhu et al [94] published a magnificent review on the structure design and its analysis of magnetorheological fluid dampers.…”

“…Recent development in the study of control strategies requires veracious output-feedback signal, which depends on the performance of signal pickup assembly and an appropriate measuring method to achieve beneficial performances such as isolation for moving vehicle 6,7,8 and vibration suppression for precise instrument on micro air vehicle (MAV). The usual signal measurement method contains sensor (i.e.…”

Design and performance evaluation of a novel magnetorheological valve with a tunable resistance gap

“…It exhibits unusual characteristics in that its rheological properties can be continuously and reversibly changed within milliseconds by applying or removing a magnetic field. This interesting property has inspired the design of a large variety of MRF devices in various engineering applications such as MR valves [3][4], shock absorbers and dampers [5][6], engine mounts, and clutch systems [7][8]. Of these devices the MR valve is generally used to control the speed of the hydraulic actuator of MRF because it has many advantages, including: valves with no moving parts, the complexity and durability issues in conventional mechanical control valves is removed, and a direct transduction from an electrical control signal to a change in mechanical properties is provided [9][10].…”
