“…The radius component of the magnetic field intensity (H) is small at the end of the disk faces, so its effects is negligible on the exerted torque [21]. Many researchers employed 2-D axisymmetric numerical simulation to find magnetic field distribution on the disk and employed equation (7) to calculate the induced magnetic field torque on the disk [16,17,21,22,30,31,[33][34][35].…”

Magnetorheological (MR) brakes have attracted many attentions for controlling mechanical systems such as robots, e-bicycles, and haptic devices. A large number of researchers have delved into enhancing MR brake effectiveness. Herein, a new MR brake is proposed in which the braking torque is improved and the configuration is simplified. Numerical simulations were based on finite element method (FEM) was employed to achieve the brake model. In order to verify the obtained results, they were compared with the available ones in the literature and they have a good agreement with each other. Then, the proper brake model was optimized using Nelder–Mead optimization algorithm. Results demonstrated 215.75 N m braking torque in the present prototype which is almost 73% higher than the previous model in the literature. In addition, the brake could induce about 125.06 N m torque on the brake disk with nearly half of the coil current used in the previous work. Besides, increase in the number of the disks was not necessarily improved braking efficiency and the size of the MR fluid gaps also influenced the brake operation. In addition, the proposed model in this paper has ease manufacturing procedure which would reduce the fabrication costs.

This work aims to investigate the elastic wave propagation in the periodic impedance layered structure filled with magnetorheological fluid. The periodic impedance layered structure with high and low impedance layers is constructed by using the magnetorheological fluid with the controllability of liquid–solid conversion. The principle of the periodic impedance layered structure is presented. The transfer model of elastic wave in the proposed structure is established, and the propagation velocity and attenuation coefficient of elastic wave curves of the periodic impedance layered structures with different distribution modes are obtained. The prototype of experimental setup is designed and fabricated, and the experimental testing of the vibration transmissibility is conducted. The theoretical model is validated by comparing the results with the experimental measurements. The results suggest that appropriate distribution modes and also applied magnetic field are validly showing greater attenuation for elastic wave propagation in the periodic layered structures. Theoretical and experimental studies are conducted to investigate on the vibration transmissibility of the proposed structure, the findings of which contribute to provide guidance for the future vibration isolation platforms of the power systems in aerospace and marine engineering practical applications.

“…In recent years, the study of the load transfer in the structure has achieved a growing attention from mechanical engineers, specifically in the vehicle industry [2]. Hajiyan et al [3] proposed a new design for an automotive magneto-rheological (MR) braking system using multiple rotary discs. Gray cast iron has been the primary material for automotive brake rotors (discs) because of its excellent thermal transport ability and its damping properties.…”

The braking phenomenon is an aspect of vehicle stopping performance where with kinetic energy due to speed of the vehicle is transformed to thermal energy via the friction between the brake disc and its pads. In our work, we presented numerical modeling using ANSYS software adapted in the finite element method, to follow the evolution of the global temperatures for the two types of brake discs, full and ventilated disc during braking scenario. Also, numerical simulation of the transient thermal and the static structural analysis were performed sequentially, with coupled thermo-structural method. Numerical procedure of calculation relies on important steps such that the Computational Fluid Dynamics and thermal analysis have been well illustrated in 3D, showing the effects of heat distribution over the brake disc. This CFD approach helped in the calculation of values of the heat transfer coefficients (h) that have been exploited in 3D transient evolution of the brake disc temperatures. Three different brake disc materials were tested and comparative analysis of the results was conducted in order, to derive the one with the best thermal behavior. Finally, the resolution of the coupled thermomechanical model allows us to visualize other important results of this research such as; the deformations, and the equivalent Von Mises stress of the disc, as well as the contact pressure of brake pads. Following the analysis of the results obtained, we draw several conclusions from this investigation. The choice allowed us to deliver the excellent rotor design to ensure and guarantee the good braking performance of the vehicles.
