The hydrostatic dynamic characteristics will change with different restrictors of structure, flow rate and pressure. In this paper the hydrostatic system parameters M (system mass), C (coefficient of viscous damping) and K ((coefficient of stiffness) are identified. In general the system mass is constant, but C and K will be changed with time and displacement. Firstly, the transient response of the system is obtained. Then using curve fitting we identify the hydrostatic bearing dynamic parameters C and K.
