“…The braking torque of MRF brake system can be linearly being manipulated using an excitation current in few milliseconds. Benefits of using MRF brakes such as less response time, no brake fading, no linkage and secure electrical interface [5] enables the exploration regarding MRF brakes become more attractive and actively being investigated recently.…”

This paper presents an application of Second Order Sliding Mode Controller (SOSMC) to regulate the vehicle longitudinal slip using Magnetorheological Fluid (MRF) brake as an actuator for the vehicle braking system. A quarter vehicle with a simple Bingham model is adopted as the control plant and the MRF brake system model respectively. Numerical assessments are conducted for various types of the road surface with the main objective to regulate the longitudinal slip at its optimum friction value. Since the control system is regarded as a highly nonlinear environment, the utilization of SOSMC is considered as decent control solution to cope with the system uncertainties and at the same time reduced the system chattering effect caused by conventional sliding mode control. Results show that the targeted optimum slip reference can be achieved with a smooth input signal compared to conventional SMC.

“…MRF has been utilized in dampers [4,5] and brakes [6] due to its unique ability to modify rheological properties by adjusting the strength of the magnetic field. As a result, the proposal of using MRF in car braking systems [7][8][9] has been presented, with a target torque of at least 500 Nm for the usage of 1000 kg automobile [10]. As a result, numerous ways to improving the torque performances of MR brakes for automotive applications have been adopted.…”

Effect of Magnetorheological Grease’s Viscosity to the Torque Performance in Magnetorheological Brake

et al. 2022

Recently, magnetorheological grease (MRG) has been utilized in magnetorheological (MR) brakes to generate a braking torque based on the current applied. However, the high initial viscosity of MRG has increased the off-state torque that led to the viscous drag of the brake. Therefore, in this study, the off-state viscosity of MRG can be reduced by the introduction of dilution oil as an additive. Three samples consist of pure MRG (MRG 1) and MRG with different types of dilution oil; hydraulic (MRG 2) and kerosene (MRG 3) were prepared by mixing grease and spherical carbonyl iron particles (CIP) using a mechanical stirrer. The rheological properties in the rotational mode were examined using a rheometer and the torque performances in MR brake were evaluated by changing the current of 0 A, 0.4 A, 0.8 A, and 1.2 A with fixed angular speed. The result shows that MRG 3 has the lowest viscosity which is almost 93% reduction while the viscosity of MRG 2 has lowered to 25%. However, the torque performances generated by MRG 3 were highest, 1.44 Nm, when 1.2 A of current was applied and followed by MRG 2 and MRG 1. This phenomenon indicated that the improvement of torque performances was dependent on the viscosity of MRG. By reducing the viscosity of MRG, the restriction on CIP to form chain formation has also decreased and strengthen the torque of MRG brake. Consequently, the utilization of dilution oil in MRG could be considered in MR brake in near future.
