The automotive damper is one of the important components of a vehicle suspension system. It controls spring motion by damping energy from the spring, and it is used for the optimization of driving comfort and driving safety. Many automotive dampers have non-linear asymmetric characteristics to accommodate the incompatible requirements between ride comfort and road handling, the engineer requires techniques that can characterize this non-linear behavior and provide models of the dampers for use in ride performance simulations of the full suspension system. In this paper, experimental characterization is done by developing a mathematical model of the front wheel gas-filled hydraulic damper of Maruti Suzuki swift corresponding to road conditions. The dampers have tested under both sinusoidal and ramp excitations on the dynamic material test platform. To accurately predict damping force experimental data is used to fit the equation of curve using the least square curve fitting method in Matlab software interface and components of the mathematical force model is identified. Finally, results of a mathematical model are verified with experimental results. The results of the mathematical model show good correlation with experimental data with precision above 90%. Though some error has been found. It is mainly due to hysteresis effect which is present because of damper compliance.
