Magnetorheological Fluid

What Is Magnetorheological Fluid A magnetorheological fluid is a type of smart fluid in a carrier fluid, usually a type of oil. When subjected to a magnetic field, the fluid greatly increases its apparent viscosity, to the point of becoming a viscoelastic solid. Importantly, the yield stress of the fluid when in its active ("on") state can be controlled very accurately by varying the magnetic field intensity. The upshot is that the fluid's ability to transmit force can be controlled with an electromagnet, which gives rise to its many possible control-based applications. Extensive discussions of the physics and applications of MR fluids can be found in a recent book.

Magnetorheological Fluid Technology: Applications in Vehicle Systems compiles the authors’ recent work involving the application of magnetorheological (MR) fluids and other smart materials in vehicles. It collects concepts that have previously been scattered in peer-reviewed international journals. After introducing the physical phenomena and properties of MR fluids, the book presents control methodologies for effectively controlling vehicle devices and systems featuring MR fluids. The authors also introduce the hysteresis identification of MR fluid and discuss its application through the adoption of the Preisach and polynomial models. They then describe the application of MR-equipped suspension systems in passenger, tracked, and railway vehicles; the application of MR brake systems in passenger vehicles, motorcycles, and bicycles; and the application of several MR technologies in heavy vehicles. The final chapter explores the use of haptic technologies for easily operating vehicle instruments and achieving optimal gear shifting with accelerator pedals. Assuming some technical and mathematical background in vibration, dynamics, and control, this book is designed for scientists and engineers looking to create new devices or systems for vehicles featuring controllable MR fluids. It is also suitable for graduate students who are interested in the dynamic modeling and control methodology of vehicle devices and systems associated with MR fluid technology.

This book contains up-to-date information on the state of the art of research and applications in electro- and magnetorheology. A total of 130 papers are presented in four sections. The first section is devoted to the various applications of ER and MR fluids, like polishing, microfluidics, vibration control, robots, shock absorbers and dampers, MR and ER valves. The second part deals with the experimental characterization as well as the theoretical prediction of the mesostructure resulting from field-induced phase separation. The dynamics of phase separation is also included in this section. The third section is about the material properties; it includes papers on new compositions of ER or MR fluids, polymer blends, magneto- or electroactive elastomers and gels. The last section, about physical mechanisms, presents experiments and theories on the rheology of the fluids and its connection with microhydrodynamics and the structure of field-induced aggregates.

Adaptronics is the term encompassing technical fields that have become known internationally under the names "smart materials", "intelligent structures", and "smart structures". Adaptronics contributes to the optimisation of systems and products. It bridges the gap between material and system or product, and incorporates the search for multi-functional materials and elements and their integration in systems or structures. The authors of this book have taken on the task of displaying the current state of the art in this fascinating field. The system components, actuators, sensors and controllers, technical fundamentals, materials, design rules and practical solutions are all described. Selected sample applications are also presented and current development trends are demonstrated.
