Review: Electro Rheology for Smart Automotive Suspension by Using Zeolite Base ERR Fluid
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
the purpose of the paper reported was to substantiate the capability of electro rheological (er) technology for adaptive control of suspension forces on wheeled vehicles. The shear strength properties of er fluid are proportional to an electric field applied. This change is quick and reversible. Electro-rheological fluids consist of slurries of fine hydrophilic solids in hydrophobic liquids. In the absence of an electric field, these fluids behave like newtonian fashion, but when an electric field is applied, the fluids become more viscous as the electric field increases. The process reverses when the electric potential is removed, and the er fluid returns to its fluid state. If we applied strong electrical field er fluid becomes solid. We can use this property in automobile suspension in the damper where resistive forces controlled by an external electrical signal. The device was applied in a semi active suspension system. The paper contains range of development tasks including er fluid formulation, design of an er damper. The design of shock absorber consists of a fluid filled cylinder and piston member travelling in cylinder and electro-rheological valve controlling the passage of fluid through the cylinder. The electro-rheological valve placed in piston to control the flow of fluid. And this design can be easily adapted in present size of shock absorbers.
