In this work, a magnetorheological (MR) damper prototype that provides controllable damping force was designed, manufactured and tested. The design and dimensions of the MR damper piston were determined according to the static magnetic analysis results made in ANSYS/Emag (Electromagnetics) software. The MR damper's damping performance was tested in laboratory by utilizing a damper testing device. The tests were carried out under different currents applied to coil of the MR damper. According to the test results, the equivalent damping coefficients of the MR damper were calculated for different currents. The test results show that the highest damping force is 169.4 N with frequency of 3.18 Hz and applied current of 2 A. In this case, the equivalent damping coefficient is 302 Ns/m. The equivalent damping coefficient is 181 Ns/m when no current is supplied to the coil. The area of the dynamic force range also becomes larger with increasing the applied current. In addition, according to the quarter car model based simulation results in MATLAB/Simulink, it was seen that the semi-active suspension system using MR damper was more effective and successful in vibration mitigation.

“…It has been reported that the ELM method shows less R2 standard deviation values than traditional artificial neural networks. Jamadar et al (2021) have investigated a commercial MR damper for various piston velocities and currents. The equivalent damping coefficient has been calculated for the tested conditions and the equivalent damping coefficients have been used for analyzing a quarter car model.…”

Describing the hysteresis behavior of magnetorheological (MR) shock absorber significantly facilitates the developers before manufacturing and control processes. However, most of the models developed to describe the phenomenon have been required experimental data of the manufactured absorber. In this study, the hysteresis behavior for a shock absorber has been characterized by developing a three-dimensional coupled numerical model that adapts Viscoelastic Maxwell Model to momentum equations of fluid flow. The viscosity of the MR fluid, which depends on the magnetic flux density, has been calculated with the Herschel-Bulkley model at each node of the fluid domain, coupled with the magnetic field analysis. The hysteresis relationship between force and velocity has been obtained from time-dependent CFD analyses on the deformed grid. It has been observed that the hysteresis behavior of the MR shock absorber has been attained with a good agreement when the data obtained from the developed numerical model are compared with the experimental data. In addition, besides estimating the hysteresis widths in the force-velocity curves, all effects and changes in time in the flow domain have been observed thanks to the model.

In this study, an active suspension model is proposed to increase the driving safety and passenger comfort of the car, which is adversely affected by car-road interaction. In this context, the full car model with a driver is considered as eight degrees of freedom. All the motion equations of the car were determined by the Lagrangian method and converted into state-space forms. Then, these equations are solved precisely by using Euler's method in Matlab software. PID and LQR controllers are designed to reduce the vertical displacement of the passenger and the rotational movements of the car. In order to evaluate the performance of the designed controllers, two different road inputs and two different car speeds are taken into account. In the simulation results, the vertical displacement and acceleration values of the driver and the rotational movements of the car were examined. While the PID controller stands out in damping the displacement values at low speeds, the LQR controller is much more successful in other cases.
