Damping and Dynamic Performance Research of Axial-winding Magentorheological Fluid Damper

To analyse damping force and dynamic performance of axial-winding magentorheological fluid damper,the damping coefficient of damper was regarded as aconstant,the simulation analysis of dynamic performance was carried out,and the relationship between coulomb damping force and current intensity was got.Real damping coefficient was regarded as equivalent linearization.the relationship between real damping coefficient and current intensity were achieved by the vibration experiment of damper.The results of simulation analysis and the results of the experiment was basically same,and the results of simulation analysis was also verified.The results show that the damping force of damper was almost provided with coulomb damping force,and it was convenient to controlled the damping force by the current.
