The future of the automotive industry thrives by the creation of a greener, more efficient and lightweight braking mechanisms. Research on utilizing electromechanical brakes have shown potential due to their superior performance and controllability. The magnetorheological Brake (MRB) is a promising electromechanical brake which can provide variable damping through variation of the MR fluids’ apparent viscosity and yield strength using the applied magnetic field. Fast response time, low power requirement and large dynamic range are among unique features of MRBs making them an ideal candidate for vehicle applications. While some design configurations have been proposed for applying MRBs in the automotive industry, the commercial application has not yet been fully realized mainly due to the existence of their zero-field viscous torque. The focal purpose of this study is to propose and develop a novel real-size vehicle model of the MRB design with absolutely no energy loss in terms of viscous torque generation. The design is achieved using permanent magnets which force the MR fluid volume to shift locations between the brake’s operating modes – ‘on’ and ‘off’ – to allow complete de-coupling. The performance of the proposed design compared with the conventional design is demonstrated on a 2-disk-type MRB configuration. The Herschel-Bulkley constitutive model is adopted for the MR fluid to derive the mathematical equations governing the systems’ braking torques as a function of the rotational speed, geometric properties, and applied electrical current. The MR fluid selected for the proposed designs is MRF-132DG from Lord Corporation. Analytical magnetic circuit analysis of the MRB design has been conducted which allows to approximately derive the relation between the magnetic field intensity and the electric current as a function of number of coil turns and the brake’s geometric variables. The analytical model is then verified using an electromagnetic finite element model developed in open source FEMM software. An equation relating densities of the materials used in the MRB and their corresponding dimensions is also derived to estimate the weight of the proposed MRB. Subsequently, a multidisciplinary design optimization problem has been formulated to identify the optimal brake geometrical parameters to maximize the dynamic range of the MRBs under weight, size and magnetic flux density constraints. The optimization problem has been solved using Genetic Algorithm (GA) followed by the Sequential Quadratic Programming (SQP) technique implemented in the MATLAB environment to achieve the true global optimal design. It is shown that the proposed MRB design provides better performance specifications under the required design constraints while having zero viscous torque generation making it suitable for application in real commercial vehicles. Finally, a simple dynamic quarter-vehicle model integrated with the optimally designed MRB has been considered to investigate the brake performance in automotive application. A PID control scheme has been designed for optimal wheel slip control over different road surface conditions. The objective is to obtain the highest value possible for the road-friction coefficient. This is possible through regulating and maintaining the slip ratio to a desired value whether driving on dry, wet, snowy or icy roads. The controller is purposed to enhance the overall braking properties of a vehicle through reducing the stopping distance and time, enhancing stability, and avoiding wheel lockup.

This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional hydraulic brake (CHB) systems used in automotive industry have several limitations and disadvantages such as the response delay, wear of braking pad, requirement for auxiliary components (e.g. hydraulic pump, transfer pipes and brake fluid reservoir) and increased overall weight due to the auxiliary components. In this thesis, the development of a novel electromechanical brake (EMB) for automotive applications is presented. Such brake employs mechanical components as well as electrical components, resulting in more reliable and faster braking actuation. The proposed electromagnetic brake is a magnetorheological (MR) brake. The MR brake consists of multiple rotating disks immersed into an MR fluid and an enclosed electromagnet. When current is applied to the electromagnet coil, the MR fluid solidifies as its yield stress varies as a function of the magnetic field applied by the electromagnet. This controllable yield stress produces shear friction on the rotating disks, generating the braking torque. This type of braking system has the following advantages: faster response, easy implementation of a new controller or existing controllers (e.g. ABS, VSC, EPB, etc.), less maintenance requirements since there is no material wear and lighter overall weight since it does not require the auxiliary components used in CHBs. The MRB design process included several critical design steps such as the magnetic circuit design and material selection as well as other practical considerations such as cooling and sealing. A basic MRB configuration was selected among possible candidates and a detailed design was obtained according to a set of design criteria. Then, with the help of a finite element model (FEM) of the MRB design, the magnetic field intensity distribution within the brake was simulated and the results were used to calculate the braking torque generation. In order to obtain an optimal MRB design with higher braking torque generation capacity and lower weight, the key design parameters were optimized. The optimization procedure also consisted of the FEM, which was required to calculate the braking torque generation in each iteration. Two different optimization search methods were used in obtaining the minimum weight and maximum braking torque: (i) a random search algorithm, simulated annealing, was first used to find an approximate optimum design and (ii) a gradient based algorithm, sequential quadratic programming, was subsequently used to obtain the optimum dimensional design parameters. Next, the optimum MRB was prototyped. The braking performance of the prototype was tested and verified, and the experimental results were shown. Also, experimental results were compared with the simulation results. Due to the lack of accurate material property data used in the simulations, there were discrepancies between the experimental and the simulation results. Other possible sources of errors are also discussed. Since the prototype MRB generates much lower braking torque compared to that of a similar size CHB, possible design improvements are suggested ton further increase the braking torque capacity. These include the relaxation of the optimization constraints, introduction of additional disks, and the change in the basic magnetic circuit configuration.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A novel electromechanical brake (EMB) based on the eddy current principle is proposed for application in electrical vehicles. The proposed solution is a feasible replacement for the current conventional hydraulic brake (CHB) systems. Unlike CHBs eddy current brakes (ECBs) use eddy currents and their interaction with an externally applied magnetic field to generate braking torque. Due to their pure electrically controllable and contact free nature, ECBs have multiple advantages over the current CHB systems, such as faster response, reduced weight and number of components, ease of implementing various controllers (e.g., anti-lock braking), and reduced noise levels. However, the torque generated by a typical ECB at low speeds is insufficient to effectively and completely stop a moving vehicle. Therefore, an ECB is commonly used as an assistive brake to the CHB system in heavy vehicles, i.e. trains and trucks In order to overcome this shortcoming, the use of AC magnetic fields is proposed to realize a stand-alone ECB system in which sufficient braking torque can be generated at low speeds. To this end, eddy currents are modeled analytically using the governing Maxwell's equations with the consideration of time varying field application. The analytical model was validated using finite element analysis. Results show that the braking torque increases with the application of a time varying field. Various forms of time varying fields have been studied. It was found that thefrequency-modulated applied field in triangular waveform results in the highest braking torque. Next, the design was optimized to maximize the braking torque and an optimum configuration was obtained using multiple pole projection areas (PPAs). Optimization results show that the braking torque significantly increases with the introduction of additional PPAs to the configuration, and the braking torque generation for an optimum four-PPA ECB configuration exceeds the braking requirements for current passengervehicles. For control purposes, a dynamic model for a novel stand-alone ECB system using AC fields for automotive applications has been successfully designed and evaluated. Also, a model-based predictive controller has been developed for the optimum ECBconfiguration. Finally an experimental test-bed has been designed for experimentation of both DC and AC field application on ECB.
