The twin-tube dampers are more popular due to their outstanding controlling and regulation qualities in most driving conditions with cost-effective. Magnetorheological (MR) dampers are used in automotive applications to boost damping force while maintaining geometric constraints. Two significant parameters considered while evaluating an MR damper’s efficiency are valve ratio and controllable force. These parameters are used to define a geometric configuration of an MR damper. The effective damping force increases according to the magnetic field strength. The magnetic circuit analysis reveals that the damping force is directly proportional to the applied current. The proposed model can significantly improve the suspension damping effect for high-speed applications.
