Abstract

The design method of a cylindrical magnetorheological (MR) damper is established. The viscosity model is used to describe the viscous characteristics of the MR fluids subject to an applied magnetic field. The equation for the damping force is derived to provide the theoretical foundation for the design of the damper. Based on this equation the engineering expressions for the gap and effective length of the annular MR fluid between the piston and the outer cylinder are derived. The values of the gap and length can be calculated when the required damping force, the velocity of the piston, and the desired control damping force ratio are specified.
