Nonlinear physical parameters of the docking mechanism-inertial, damping and stiffness matrices, are identified by direct parameter estimate(DPE)method with input-output data of the system.
Results show that damping moment modulus of damper with given size and liquid medium is almost constant and basically in direct proportion to square of rotor speed.
