EasyChair Preprint 1588

Abstract

Abstract: The performance of the magnetorheological damper is determined based on the damping force obtained which will be used to reduce the vibrations in specific application .In this paper, a axisymmetric Magnetorheological damper model is analysed using ANSYS finite element analysis to simulate a distribution of the flux density of the applied magnetic field for the SA1018 and Aluminium materials in Magnetorheological damper for a given current in shear mode operation. The model which gives the maximum flux density is taken for further study the effect of shear gap and shearing length of the damper. Then the comparative study on the effect of variation of shear gap and effective length on magnetic flux density, where the damping force which is dependent on the magnetic flux density is obtained and by using the response surface methodology optimum values are obtained for maximum flux density.
