“…Based on the control results, it was confirmed that the vertical vibrations of railway vehicles can be significantly reduced using the proposed semi-active suspension strategies. Recently, Jin et al [47] developed a novel type of semi-active suspension featuring a MR damper and elastomer. Table 4 summarizes many different recent studies on MR dampers for military and railway engineering.…”

This review article presents various multi-DOF application systems that utilize smart magnetorheological (MR) fluid. It is well known that MR fluid has been actively studied and applied in many practical systems such as vehicle suspension dampers. The design requirements for the effective applications of MR fluid include geometry optimization, working principles, and control schemes. The geometry optimization is mostly related to the size minimization with high damping force, while the working principles are classified into the shear mode, the flow mode, and the squeeze mode depending on the dominant dynamic motion of the application system. The control schemes are crucial to achieve final targets such as robust vibration control against disturbances. It should be addressed that advanced output performances of MR application systems heavily depends on these three requirements. This review article presents numerous application systems such as sandwich structures, dampers, mounts, brakes, and clutches, which have been developed considering the three design requirements. In addition, in this article some merits and demerits of each application system are discussed to enable potential researchers to develop more effective and practical MR application systems featuring the multi-DOF dynamic motions.

“…As far as semi-active dampers are considered, it has been found that MR damper is quite promising for vibration control applications [8]. Some efforts have been taken to illustrate the feasibility and effectiveness of the controlled MR dampers on railway vehicle suspension systems [9]- [13]. MR fluids, which are used in MR dampers, are amongst controllable fluids that respond to applied magnetic fields with dramatic changes in rheological behaviors.…”

The rail irregularities and wheel-rail interactions in a train running at high speeds may result in large-amplitude vibrations in the train's car body and affect passengers by reducing ride comfort. The train suspension systems have a crucial role in reducing the vibrations and improving ride comfort to an acceptable level. In this context, an exclusive magneto-rheological (MR) damper with a favorable dynamic range was designed and fabricated. The MR dampers were installed in a high-speed train's secondary lateral suspension system, replacing passive hydraulic dampers to mitigate vibration of the car body and keep the ride comfort level in a proper condition. A unique full-scale experimental investigation on the high-speed train equipped with MR dampers was carried out to evaluate the MR damper functionality in a real operating situation. The full-scale roller experiments were conducted in a vast range of speeds from 80 to 350 km/hr. At each speed, different currents were applied to the MR dampers. The car body dynamic responses were collected with accelerometers and displacement sensors mounted on the carriage floor and sidewall. To investigate the ride quality of the high-speed train, ride comfort indices and car body rolling motion are evaluated. Ride comfort indices under various train operating conditions are calculated through Sperling and UIC513 rules. This study reveals that the designed MR dampers effectively reduce the car body's rolling motion. According to Sperling ride comfort index, the car body vibration was "clearly noticeable" at some running speeds when adopting the MR dampers, but it was not unpleasant. Besides, a "very good comfort" was achieved according to the UIC513 ride comfort criterion. Also, no train instability was whatsoever observed at high speeds.INDEX TERMS High-speed train, MR damper, full-scale experiment, ride comfort index, rolling motion, secondary suspension system.

The application of magneto-sensitive (MS) rubber in a vehicle vibration control area is likely to be expected. This conclusion is based on the following two reasons: the maturity of fabrication of MS rubber which meets the application requirement and the feasibility of the constitutive model of MS rubber that accurately reflects its mechanical performance. Compared with the traditional rubber, small ferromagnetic particles are embedded in the elastomer of MS rubber, leading to a change of mechanical properties when an external magnetic field is applied. Therefore, devices with MS rubber, can be viewed as a semi-active actuator. In this study, MS rubber with a relative high increase in the magneto-induced modulus is fabricated and characterized. Furthermore, a one-dimensional constitutive model to depict the magnetic field-, frequency-, and strain amplitude-dependent dynamic modulus of MS rubber is applied. Finally, simulations of a MS rubber semi-active suspension under a bump and a random ground excitation with different control strategies on a quarter vehicle model are conducted to illustrate the feasibility of the MS rubber in the vehicle vibration control application context.
