This book was released on 2015 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: MagnetoRheological (MR) dampers are controllable shock absorption devices that are vastly used in vibration and motion control applications. MR dampers can provide an adjustable damping constant that can be used to generate controlled damping force for vibration and shocks control. In this research different methods of reducing the weight and power consumption of MR dampers are investigated. First, optimal design of MR dampers using a Genetic Algorithm is presented. Next design of novel magnetic circuits and damper mechanisms for reducing the weight and power consumption is investigated and a new low-power, low-weight mechanism is proposed. Experimental results for the proposed MR damper are further presented and compared with the results obtained from a conventional MR damper.

Book excerpt: Mountain biking has significantly evolved recently, thanks to utilizing cutting-edge technologies in mountain bicycle design and fabrication. In this research we study development of a semi-active suspension system using magneto-rheological (MR) fluid dampers instead of conventional oil based shocks. MR dampers are devices with magnetic field dependent damping characteristics.Low power consumption, high controllability, quick response, and high durability are among the major features of MR dampers. In this work we first investigate the damping characteristics of MR dampers to find out if characteristics comparable to the conventional shocks used in mountain bikes can be achieved. To this end,experimental tests were performed on an off-the-shelf MR damper. The results indicate that damping characteristics similar to the ones used in mountain bikes can in fact be achieved using MR technology.However, requirements such as small weight and wide dynamic range have to be addressed in designing a MR damper for mountain bikes. These considerations are studied in this thesis by formulating a simple design followed by a constrained optimization problem and designing the damper accordingly. Utilizing Finite element modeling and simulation tools are further utilized to fine tune and optimize the design.A prototype MR damper is fabricated after the above design steps are carried out.

This book was released on 2018 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: MagnetoRheological (MR) dampers have been used as reliable electronically adjustable shock and motion control devices in the past few years. Although these dampers have proven their performance in practice and the cost has decreased, their usage has been limited to high-end applications. The main drawback of MR dampers is their relatively large weight and energy consumption when compared to their passive counterparts. In this thesis, we investigate factors affecting weight and energy consumption of MR dampers and devise solutions to achieve energy-efficient and light-weight dampers. To this end, an analytic approach is presented to design and build a low-energy consumption and lightweight MR damper. It is shown that the proposed configuration can decrease the mass of MR damper significantly and reduce the energy consumption when AlNiCo alloys are utilized in the magnetic core. A proof-of-concept MR damper for mountain bike applications is designed, fabricated, characterized, and tested in the field, which meets the requirements in mountain bike industry in terms of energy consumption, compression and rebound forces, mass, size, and on-the-fly adjustability of the damping forces, by the user.

This book was released on 2015 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magneto rheological (MR) fluid based dampers are very promising for semi-active or adaptive suspension control system which is filled with MR fluid. Its huge advantages attract the researchers to use it in more advanced application. MR damper's damping force can be controlled by changing the viscosity of its internal magneto-rheological fluids (MRF). However the requirement of external power source is one of the major concerns. Self-powered MR damper is one of the recent advancement which is accomplished only for double ended MR damper. In this work an energy generated mono tube MR damper has been designed and investigated with power generation which has a huge demand in the vehicle suspension system. This damper combines the advantages of energy harvesting (reusing wasted energy) and MR damping (controllable damping force). This multifunctional integration would bring great benefits such as energy saving, size and weight reduction, lower cost, high reliability, and less maintenance for the MR damper systems. The proposed MR damper model consists permanent magnet and coil combination of energy generation. Two magnetic fields are induced inside this damper. One is in the outer coil of the power generator and another is the piston head coils. A 2-D Axisymmetric model of energy generated MR damper is developed in COMSOL Multiphysics where it is analyzed extensively by finite element method and its hardware model is tested by Universal Testing Machine (UTM). The complete magnetic isolation between these two fields is accomplished here, which can be seen in the finite element analysis and damper characteristic analysis. The energy generation ability of the MR damper model is tested by UTM and oscilloscope combination and the maximum output voltage is measured around 0.8 volts by oscilloscope. Finally, experimental dampers characteristic analysis is performed by using RD-8041-1 MR Damper. These results are compared with the hardware model experimental results, which clearly validate the hardware model damper characteristic.
