Classical hydraulic dampers are flexible devices that are used to attach a component to a mounting base. Vibration amplitude reduction can be achieved by improving the old technique of suspension by bringing in application of Magnetorheological or Electrorheological fluid in it. Due to the controllable characteristics of the material used in the classical hydraulic damper, the design and application of such devices has been area of recent interest.

Completely new design of dampers for the existing systems is a complicated process. To manufacture a new MR damper, new process needs to be developed which may become cumbersome. Considering this requirement, classical damper was modified into MR damper by using an external arrangement without any changes.
