“…To determine the capability of the MRB in a wheel decelerating, a validate wheel dynamic model with MR fluid type 132-AD [30] that have been used is shown in Figure 1. As illustrated, it consists of a drive shaft that connects to the three-phase motor through belting that provides a throttle torque, an MRB that provides the brake torque and a steel load that represents a dynamic wheel.…”

“…The MRB consists of three parts that are a moving rotor, a static body and a winding coil. Moving rotor and a static body are made from mild steel and a winding coil that has been used in this design are made from bronze wire [31]. Meanwhile, a connection between MRB and a drive shaft that consists of the moving rotor is linked to the drive shaft via jaw coupling.…”

“…In this experiment, the capability of the MRB is determined by using the same test rig that has been used in [31] as shown in Figure 2. It consists of an electric motor to actuate a drive shaft via an A-type V-belt, load cells that have been coupled with a 238 mm arm to sense a brake torque that is produced by MRB and a wheel speed sensor to sense an angular velocity of a drive shaft.…”

“…The MRB model is developed by following the behaviour trend of MRB that is gathered through experiment. The MR brake actuator model is developed based on the characteristics of the MR brake, where the brake torque increases proportionally with apply current and independent speed [30], [31], [32]. In this model, the actuator is designed based on rotational wheel speed, and it is assumed that the torque remains the same at all speed.…”

“…Based on the proposed technique, the braking torque at a constant steady-state can be achieved. By referring to Figure 4, the MRB actuator model consists of 6 blocks, which represents the brake model based on an actual characteristic of MRB obtained from the experiment in Zainordin et al [30]. Each block is connected to the shifting block as a function torque selector depending on the wheel angular velocity by referring to Eq.…”

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.
