“…The MRB model needs to be verified with the experiment in order to study the wheel angular velocity and braking torque responses. Based on the numerical model that has been developed by [28], the responses of wheel angular velocity and braking torque are similar to this experiment. In addition, the MRB torque proportionally increases when the current increases and independent of the rotational speed.…”

“…To access the compatibility between theory or simulation, the evaluation has been made by comparing the wheel speed and brake torque response between simulation and experiment. Noted that the MRB design, the test rig, as well as the characterisation of the brake design that has been used in this study, can be found in [28] and [29]. The outline of this paper has been arranged as follows; the first section introduces MR fluid in the vehicle brake system.…”

This paper presents the testing of a Magnetorheological brake (MRB) in the braking system of a vehicle. Two techniques are used to determine the capability of the brake system which are the simulation via Matlab Simulink Software and experimental study by using a quarter vehicle test rig. A Proportional-Integral-Derivative (PID) is employed as a wheel speed control as well as to enforce the MRB to produce the required braking torque need by a vehicle. A dynamic test, namely sudden braking test is performed in three rotational speed conditions which are from 127.5 rad/s (1200 rpm) to 31.42 rad/s (300 rpm), 52.37 Rad/s (500 rpm) and 73.31 rad/s (700 rpm) in two different wheel load which are 10 kg and 15 kg, respectively. The behaviours to be assessed are wheel speed response and brake torque produced by the MRB. From the observation, it is concluded that the capability of the MRB in providing the required brake torque is promising and harmony between simulation and experimental response.

“…Karakoc et al (2008) designed and optimised the structure parameters and material parameters of MR brake using a series of quadratic programming algorithm, and the optimal brake parameters were tested by experiments. Zainordin et al (2013) built the mathematical models of angular velocity, torque and displacement based on an MR brake test rig, and compared the experimental data to the simulation results under different excitation current. Ubaidillah et al (2014) used the finite element model of MR brake to analyse the change regularity of magnetic line of force, magnetic field strength and magnetic field density by changing the applied excitation current, and then built an MR brake test rig to obtain the change regularity of shaft speed and brake torque under different excitation current.…”

Abstract:In order to solve the problem of modelling, simulation and optimisation of magnetorheological brake (MR brake) which is a multi-domain coupling system, the braking performance and control parameters optimisation of MR brake were investigated under a quarter-car model. Firstly, based on Modelica/MWorks platform, using multi-domain unified modelling method, a multi-domain unified MR brake model with anti-lock braking system (ABS) was built. Then by using response surface method (RSM), the response surface function to express the relation between braking distance and three control parameters was formulated, and the optimisation problem of control parameters was solved at MWorks. Finally, according to the optimal control parameters and the structure parameters of MR brake designed by our group before, the simulation of the multi-domain unified MR brake model was done to analyse the change regularity of vehicle speed, slip ratio, braking distance, control current, braking time, etc. under the effect of controller. Results show that MR brake with optimal control parameters has a good braking performance and can meet the requirements of GB7258-2012 standard. This lays the foundation of application of MR brake in vehicles.

“…The Xby-wire system has been employed in several vehicle areas such as vehicle steering, suspension and braking systems [1][2][3][4][5]. The MR (magnetorheological) brake is an X-bywire system that employs MR fluid where the fluid thickens dramatically under the influence of a magnetic field.…”

This paper presents a performance evaluation of a shaft speed control using a magnetorheological brake (MR brake). The MR brake consists of a rotating disk that is immersed in magnetorheological fluid (MR fluid). The rheology of the fluid changes under the influence of a magnetic field. Two controllers are proposed in this work: onoff and proportional-integral-derivative (PID). The on-off controller acts as the benchmark controller through computer simulation and experimental testing. Load tests have been considered in order to evaluate the controller's effectiveness in braking the wheel shaft at 50, 100 and 150 N in varying speeds of 300, 500, 700 and 900 rpm. The results obtained in the simulation and the experiment are compared and discussed. The PID controller shows good performance compared to the on-off control where the error percentages of the PID control, which are below 10%, are lower than the on-off controller.
