Electromagnetic shock absorber using Magnetorheological Fluid

One of the main criteria of any vehicle suspension is the shock absorber which is used to absorb vibration. Description of a vehicle such as driving comfort and control over a vehicle are mainly decided by the suspension system which transmits forces between vehicle and road. In this case for controlled suspension Magnetorheological fluid is employed. Magnetorheological fluid consists of magnetic particles of micron size which are suspended in a carrier fluid like oil. Magnetorheological fluid has the capability to change its viscosity as the surrounding magnetic field changes. Like the conventional suspension systems, electromagnetic shock absorber also has no mechanical valves or small moving element that can wear out.
