摘要：
In this paper, a general method, for solving a wide range of parameter identification problems of rotors is proposed and described, which formulates the parameter identification as an optimization problem. It needs data of several monitoring points, not of all nodes of a rotor. According to this method, several examples are presented to idenfy oil-film stiffness, unbalance, crack location and size, rub location of experimental or simulated rotor by means of optimized method.
